#3006 is the same as M0 but with a message. Do you have to press cycle start twice? I use this all the time in programs, usually between tool changes, to have the operator clear scrap, fasten a part down, rotate a part, etc. He hits cycle start and program continues. #3006=1 (MESSAGE) is part of my default insert manual code in Mastercam. 👍
sooo my fanuc didnt have a internal program to do cavity type operations ... so i spent a good day at home outside of work hours..... and made this abomination. when i made it i was warking in italy so comments are in italian . not changing it for this post just google translate things :D % :0887(SVUOTAMENTO CIRCOLARE) (VERSIONE 2.0 PERL)

I watched the video for the first time and then I said, boy, this video needs a cup of tea, a notebook and a pen, there is really a lot of information in this video that needs to be jotted down, thank you guys for this video, especially the rap song at the end of the video, you made me laughing alot 😂
This is what separates master machinists to machinist GODS. I've been testing macros for a year on my turret doosan, usually for knowing how long the bar stock is before changing to a new bar, or for milling polygons as Manual Guide i doesn't have a cycle for face milling polygons on my machine. You can even use macros for calculations while in a toolpath, if you want to make an elliptical shape or anything that is not a cone or a circle with some math included without a cam software. When done right, it is beautiful, efficient and, your co-workers who probably don't even know what a macro is will think you're doing some black magic and put their professional knowledge in question. On a technical note, always prefer using conditional loops such as WHILE rather than GOTO statements to avoid some nightmare situations. One interesting book about macros is CNC Programming using Fanuc Custom Macro B, by S.K Sinha. The author also replies to emails with technical questions and is much responsive on cnc forums
Love the video. I once altered a cnc heater band cutting tool path so it could handle differing slot lengths and any kind of clearances. Commented the living daylights out of the top page explaining what the variable did on the program. Showed the boss a simulation and asked if we could try it. Long story short, less cutting time, everything matched up, and less cutter sharpening. This also freed up the cam programmers to concentrate on one off programming. And yes I got a nice raise too boot.
As a regular computer science student and certified programmer it's interesting to see how similar but also how extremely different gcode macro coding is to other languages like c++, Java, or python. It's all the same kind of logic at the base level. This actually reminds me of coding in assembly language now that I think of it.
Yes macro B uses the same kind of line by line logic as the older languages such as BASIC as opposed to the OOP approach of C++ and Python. Who knows, perhaps CNC controls will all us to write our classes one day. 😅
Busting out a nearly 20 year old book Peter Smid at the beginning; FANUC CNC custom macros, Programming resources for Fanuc Custom Macro B users And yet because of how archaic G code is(Develop around the same time as FORTRAN), that book is still relevant. On the plus side G code is still being updated which is why Marcos and conditional loops are a thing. Now if only the manufacturers would actually standardize their G code and Macros.
It's wild seeing this as a regular computer developer. This goes right back to the earliest ways of programming with explicit GOTOs and persistent global variables called macros for some reason...
You can actually do the whole tool life macro (for all the tools) in a subprogram. This keeps your main program much cleaner and shorter. There are also so many more uses for these macros, for example automatically calculating the origin point of the piece (even for both spindles if your machine has them). Also for dual spindle you can calculate where the 2nd spindle should go exactly when taking the workpiece from the 1st spindle using macro and subprogram (to keep main program clean and short). I've done a whole system like this (more stuff than I wrote here) for myself when I was in school, even tho these things are not taught in school. I wish I could have a job like these guys where I can try stuff and discover better systems.
Why can you not have a job like this? I’ve been doing this for 17 years and I can clearly see you know what you’re talking about. You don’t have to wish anymore dude.
This is control specific. Especially with fanuc controls. I highly recommend you read the machine manual AND the yellow fanuc books that come with your machine. With most fanuc controls you'll need a #3000 under your M30 or "end of record" M code.
I program at a job shop with machines that are mostly 35+ years old. Macros and Subs help me keep my programs small enough to fit in the 32k-1024k of program memory I have. Also, I make macros for simple operations so the machinists can punch in a few variables and get stuff like helical plunge operations without bothering me
helical plunging is a waste of time prefer to plunge point for pocketing dynamic. also subroutine G91 G03 I-. Z-. for counter bores much easier to identify, edit, much faster
Now that Iv mastered g code… I’m on to learning macros, and boy is it so much more difficult 😂I know 2 people that add their own custom macros for in process inspection and automatic tool changed after life expires and retouch off with tool break detect too, if you ever find guys that can make programs fool proof for lights out like that, pay them in gold and never let them go
I got a 3 axis vertical mill. Fanuc control. With very little memory. I would like to run multiple vises and run more parts without creating longer programs and sometimes you may only be able to setup one or 2 vises. With each vise being assigned G54, G55, G56, etc. Is it possible to write a macro to change the work offset in each tool block to cycle through G54, G55, G56? May make for a informative video? Great job with all your doing! Helping us all means a lot!
There are a few ways to do this, but sticking with what was in the video, you could do the same format, run your program in g54, hit 601, your 1234 takes you to a g55, since that's modal, your program can run assuming you don't have 100 g54s in the way, then 602 takes you to g56. Or something like that. You can sit down and write it out
most fanuc controls can switch the work offset just by typing G54, G55 etc. (that's why they actually called G..) so the program will be as simple as G54; M98 P0001; G55; M98 P0001; ... M30;
Donnie taught me Threadmilling macros when he was at my shop while as an application engineer for a different project and now I’ve copied that macro to all our mills and we use the crap out of it 🤘🏻🤘🏻🤘🏻
@@VanillaGorilla_Machinist ohhhhh yea! I remember writing that with you guys! It was on an OKK if I recall! Glad it works out for you guys that’s so cool to hear!!!
Excellent video Donnie! I’d get in trouble if I was caught using the macro part counter back in the day because the supervisor didn’t understand macros and was afraid the machine would crash. LOL “GOTO” on the other hand, was a lifesaver for proving out programs and picking up with where I left off in general. I’ve also heard you can create your own alarms too! I never had the opportunity to ask the guy who figured it out; probably for the better because you know there would be some witty intent behind it 😆
For part counter there is M54 on fanuc controllers that does just that. On some machines there will be an alarm when you reach the number you want, some other machines don't care and keep going
Can you show a way to write a macro to keep track of time from a cycle start to a cycle start? I am wanting an easy way to track time per part including setup for billing purposes. The machine (Haas) tells cycle time but I want to easily track part to part time. Trying to stopwatch is a pain 😆
Donnie the magician introducing us into the dark arts of macro's in programming. :D Well all in all no black magic if you know what you doing, much appreciated to show a glimps of whats going on inside the blackbox for people not that familiar with it or still learning! Also really nice to throw the whole macro code in the comments!
I did a macro program for a tapered stud for a customer, they called me in to do a new version of the stud about 2 years later, I changed 3 variables and the machine was making parts.
I’ve been super curious about macros so this was pretty cool would definitely like to see more. Also Donnie I’ve said this before but you got mega ninja turtle vibes my dude
do you mean just the normal helix? you don't need a macro for that. I will write you an example of how I do it (Heidennhein) G0 X0 Y0 Z50 G0 Z10 G1 Z1 F... G43 X=50:2 ( 50 is the diameter of the hole in millimeters ) G41 G3 Z-20 I0 J0 K-1 ( K-1 means that when the tool is working, the shift is 1mm downwards for one round. in this case, the tool will make 20 circles downwards ) G3 I0 J0 ( I only do this to clean the bottom of the hole ) G40 G1 X0 Y0 G0 Z100
@@donniehinske yes. I work on a 4axis mill on FANUC. Basically I use mostly build in instructions from machine. But i'm curious if it is possible to make a macro for making a circular hole but with spiral toolpath like from cam software. Normally fanuc does it like this. Drop down in pre drilled hole or pocket then it makes a circle then adjust one step into the material and then another circle upsizing hole with each circle by that step u programmed in built in cycle. It would be awesome to do it like from cam where you have constantly increasing diameter in which tooll traverses. With macro i think you can program end diameter you want and then program step of that spiral. It would need to include that incremental instructions but it is hard for me to grasp yet. Sorry for bad english. Thanks for reply love your content ppl and all of it. Best wishes from Poland! BOOM!
@@Yamototamto I see what you are saying. Let me start jumbling that around in my mind and I’ll think of something. I’ve written circular interpolation macros before like you are saying I’ve never had it increase diameter as it does the circular movement (spiral) like you are saying. It CAN be done though. Nothing is impossible! Stay tuned for a video
Great video. I was pleasantly surprised to see that book, the very same one I got my company to buy me many years back. And I still use it today when I need to reference or refresh my knowledge. Once I discovered Macro B it was a game changer for many of my had written programs.
Excellent video guys, it's so good that you're showing it off on a Fanuc controller! There are just so many of them out there and macro stuff is super useful. It's just such a shame that Fanuc isn't producing anything similar...
Awesome Donnie, I have one for you that I've wanted for quite some time: A macro that can turn really long parts with seamless transitions, no lift just turning all the way to 35" and lets do it in Titanium, I could really use that!
@@Jack-yl7cc exactly. Been using Unix for 32 years now I’m learning g code so at least I have all of the different language structures down. Just need to focus on some manual programming g-code.
A video I would like to see: Creating your own g codes and incorporating macro variables(like tornos G800/G900). These variables are used in other G codes or you can even create a torx head.
You can do it. I’ve written one in the past, it’s usually dependent on an added variable for the distance travelled before the chatter starts then adjusting the speed up or down as required when it reaches that point. I found it a bit awkward to use in practice because it requires trial and error for each different type of part before they can run in production.
@@Glenrok I think the top level comment is actually talking about a macro that constantly varies cutting speed based on a randomly generated (or a seed generated / function) pattern along the programmed path (whatever that is) around a base value. This should by itself alleviate some chatter issues by itself because it'd break up resonance from building up. What you seem to be implying is a cutting speed gradient along a path which is a trial and error solution but you can guesstimate from experience a bit sometimes. Something like a 50% slowdown over a 4xD distance for example. My own experience is actually more dealing with extremely long endmills, 6xD+, occasionally had to grab a 10xD here and there to mixed success.
@@xm210c yes, that’s exactly how my macro worked. Either way it would have to effect some change in rpm based on either time or distance- obviously I chose distance for mine. I like your idea of a randomly generated number within a specified range, unfortunately I neither know or can find a function in Macro B which would produce one, so a macro would have to be written just for that which would then be called by the chatter macro. I doubt the maths to do so is beyond me- but it is beyond what I could be bothered to mess around with to find out…….😏
You miss to tell about #3901's variables which is about workpieces counter. In many cases, when we have a looped workflow we need to deal with that thing
The only way to know if a macro is not being used is to do a deep dive to every program on the machine and check for macros that are being used. Reading the documentation that comes with the machine is a good start, but I ran machines where the machine tool builder book was wrong. On top of that, you don’t know if anyone had dip there fingers in the programs on the machine. I myself will program Marcos that will return the values to null when finished as a safety check to make sure those values can’t be used somewhere else. With that being said, can you go over the basic concepts to writing programs for probing? Like how to check for low battery State Calibration procedures How to find the safest max feed rate during a non contact move and the fastest feed rate that can be use for a measuring move.
That’s a good idea, but a better idea would be to read and store any value already in the variable, then return it to that value after your macro finishes. That way, if the machine is depending on an already stored variable, it’s not jeopardised from having been returned to null…..
Never use GOTO statement in any code. Yo can learn that in the first year of University. In the next years you can learn it from experience when other try to use it. Anyway, series of programming CNC I found very productive. Keep it rolling.
If you are programming fanuc cnc it is not easy to avoid GOTO. The IF statements allows the conditional execution of a single macro statement or a conditional GOTO. Therefore if you want to condionally execute a bunch of macro ans cnc lines there are little alternatives. But I agree with you that GOTO should be avoided whenever possible.
I had no idea macros were even a thing before your thread macro video, so any video on any macro will be interesting for me. Also, are macros mostly used in swiss machines and production of big quantities of parts?
Macros can be used on almost any CNC machine. Some just may be formatted differently. Any Fanuc control with Macro B will work like this. You just may only have #500-#549 to play with
Macros can be used in a wide variety of lathes and mills. I've created mill macro program to quick write center/drill/tap programs that kick out proper speeds and feeds for simple plates, a single program for making multiple simple bushings per push off our Haas Lathe w/ barfeeder just by entering the desired OD and length, and controlling stock breaks on Swiss machines when for when you find yourself swapping bar sizes every time you run a job. They definitely take a lot of upfront programming and knowledge of what your using them for, but can save a lot of time in the end for shops that find themselves making a lot of simple parts that change sizes with the wind.
@@havokwest4359 when you learn to use a macro, programming becomes easier and the program is clearer and neater when written by hand on a machin. and the advantage is that you seem like God to operators who cannot learn and understand how macro works 😄
I ran a EDM wire 95% of the time using macros. Had it from setting up a pallet of parts, calling programs to set each position, then each program per part. Even had it changing power settings and spark gap for the same program depending on material thickness. All from changing a few numbers. Macros are brilliant and simple for operators to use. I love programming them, the harder the better. Really gets the old brain working lol.
Can you show how you would input the same macro "tool life" for multiple tools that have various tool life. Say od turn rough has 20pcs tool life. Od finish 40pcs. Cutoff 40pcs etc. I feel like your greater to or equal to main count say od turn rough of 20 would have to be in a different area. Or do you just create those macros in tandem with start at say 400 finish 401. But with all tool life? Thanks in advance
What’s the repeatability of that specific tool holder? In the past on various Swiss machines, like a Star, you’d have to pull the whole holder out, touch off, etc m, then make an offset. Just curious
I don't understand the GE line wouldn't you want that to be a LT so that the machine keeps running while it's LT ten and then when it counts up to ten have it go to m30 or m00 etc Would this work? #601=10 #600=0 N1234 Main program #600=#600+1 If[#600 LT #601]N1234 M2
Dude!! I have guys with me that can barely write G-code. They are so afraid of it and make it harder than it is. My 1st supervisor left me to go to the mill dept after 2 years operating experience. He said you're the new lathe supervisor, G1 is feed, G0 is rapid and walked away forever!! 35 years later I'm running a CNC division at a large manufacturer, and I can't get these guys to get it!!! I'm literally here watching TITAN'S of CNC on my own time!! They won't do it!!!
Really nice and informatic video im currently on a DMG Morie NLX3000, with a Mapps II OS, is it Possible to do it in a Maschine like this with the same macro code or do i have to search for the macro code for my machine?
Your machine will have #500s and up. Just find them in your offset page and make sure they aren’t being used before typing away. I know on older Mori machines the macro menu is harder to find. It’s annoying but it’s there
@@donniehinske Thank you for youre reply, i found the macro page but i never used it cause im just a trainee and for our Programm wen dont really use them
@@donniehinske I first need to ask for permission to make something like this cause it takes time, and if the machines not running the company losing money
@@donniehinske when we use the macro, we use it so that there is no problem even if the macro is used. for example: if I use #500 to define the offset at the beginning of the tool and another operator overwrites that macro with another variable, it's not a problem because when I start my program, macro #500 is set again to the value I defined. you mentioned that you have a macro of that thread stored next to it. if you defined those macro values in that program, you can later delete or change them without any problem, because the next time you start that threading program, your values will be written again in the macro you use.
cute video, you can also use GOTO to skip over a tool or tools in a program, just in case you have to change the order without bugging your programmer.
Wait,,, I have a program running in a loop, the machine increases the tool count at the m30 so it's not counting. Would I have to write a macro for each tool? Or, does anyone know how to make the machine count the tool usage while in a loop? Mazak 510c nexus mill, thank you for any help or assistance!
when I use a macro, I use it for each tool separately and I don't define the macro at the beginning of the program, but after changing the tool. I define F with a macro and then use that macro. if the operator needs to correct F, he corrects it immediately at the beginning of the tool and then he does not need to look for it in the program where everything changes the offset ( Milling )
The book is written by Peter Smid, called FANUC CNC custom macros. It's nearly 20 years old, so you can find some used copies floating around somewhere online. It's also still in print if you want to buy it brand new.
I would enjoy and make great use of a video that could probe a bore populate a work offset. I have some parts in my shop that need reworked. The swimgarms for Polaris slingshots lol.
Can you write a sub-macro where it can calculate the amount of travel a particular tool made while cutting and add that up to calculate actual tool wear? Then add that to any similar tool when programming it so you can change it out when it has reached its limit. Very cool stuff though. Similar to robotics programming, which is my field. 🤙
i'd love to see a macro for siemens, i have a siemens 840d sl controller, and the machine is automated with a robotic arm from ABB, however the camera that sends the coordinates for the part to pick to the robot is not that good. when i use marposs probe i want to be able to limit the probe if i have a part sticking out on the one side for milling it so i don't have to machine my jaws over and over again
Great video..and in fact we really need more tutorial videos about macro program..when I was working in milling machine I tried to understand macro programming many times but I failed...not because it hard..it because I didn't find any one can explain that in easy way and further more there are really few videos in TH-cam talk about this type of programming.
Great Vid .... Brings back memories of the 90's when I was punching G-code into my Haas VF 1 and VF 2 Anywho, Don, a question .... Kenametal or Valenite. And what about Boron Nitride ,( CBN ). Stay Safe

wait what if the macro variable number 600 was used by the machine manufacturer and it just happens to be 0 by chance at the time you're checking it, how to figure that out ?
Hi. We are trying to make a macro that indexes a horizontal table (B) 15 degrees . We have tried : #1=[#1 =15.] it only works for the first index. Can any one tell us what are we doing wrong?
I'm a software engineer. and looking at the Macro programming guide I can see very chaotic style of programming ther. Global variables, goto statements, implicit semantics. AKA a nightmare...
Here is the Macro used in the video for any of you that are interested.

I watched the video for the first time and then I said, boy, this video needs a cup of tea, a notebook and a pen, there is really a lot of information in this video that needs to be jotted down, thank you guys for this video, especially the rap song at the end of the video, you made me laughing alot 😂
This is what separates master machinists to machinist GODS. I've been testing macros for a year on my turret doosan, usually for knowing how long the bar stock is before changing to a new bar, or for milling polygons as Manual Guide i doesn't have a cycle for face milling polygons on my machine. You can even use macros for calculations while in a toolpath, if you want to make an elliptical shape or anything that is not a cone or a circle with some math included without a cam software. When done right, it is beautiful, efficient and, your co-workers who probably don't even know what a macro is will think you're doing some black magic and put their professional knowledge in question. On a technical note, always prefer using conditional loops such as WHILE rather than GOTO statements to avoid some nightmare situations. One interesting book about macros is CNC Programming using Fanuc Custom Macro B, by S.K Sinha. The author also replies to emails with technical questions and is much responsive on cnc forums
Love the video. I once altered a cnc heater band cutting tool path so it could handle differing slot lengths and any kind of clearances. Commented the living daylights out of the top page explaining what the variable did on the program. Showed the boss a simulation and asked if we could try it. Long story short, less cutting time, everything matched up, and less cutter sharpening. This also freed up the cam programmers to concentrate on one off programming. And yes I got a nice raise too boot.
As a regular computer science student and certified programmer it's interesting to see how similar but also how extremely different gcode macro coding is to other languages like c++, Java, or python. It's all the same kind of logic at the base level. This actually reminds me of coding in assembly language now that I think of it.
That’s interesting to hear!
Yes macro B uses the same kind of line by line logic as the older languages such as BASIC as opposed to the OOP approach of C++ and Python.
Who knows, perhaps CNC controls will all us to write our classes one day. 😅
One thing I noticed is the GT LT type statements. I'm used to >, < and = (also => ,

Busting out a nearly 20 year old book Peter Smid at the beginning; FANUC CNC custom macros, Programming resources for Fanuc Custom Macro B users
And yet because of how archaic G code is(Develop around the same time as FORTRAN), that book is still relevant. On the plus side G code is still being updated which is why Marcos and conditional loops are a thing. Now if only the manufacturers would actually standardize their G code and Macros.
It's wild seeing this as a regular computer developer. This goes right back to the earliest ways of programming with explicit GOTOs and persistent global variables called macros for some reason...
You can actually do the whole tool life macro (for all the tools) in a subprogram. This keeps your main program much cleaner and shorter.
There are also so many more uses for these macros, for example automatically calculating the origin point of the piece (even for both spindles if your machine has them). Also for dual spindle you can calculate where the 2nd spindle should go exactly when taking the workpiece from the 1st spindle using macro and subprogram (to keep main program clean and short).
I've done a whole system like this (more stuff than I wrote here) for myself when I was in school, even tho these things are not taught in school.
I wish I could have a job like these guys where I can try stuff and discover better systems.
Why can you not have a job like this? I’ve been doing this for 17 years and I can clearly see you know what you’re talking about. You don’t have to wish anymore dude.
@@cloudriz because nobody gives me a chance to prove my skills. Maybe one day I'll also get lucky
I have to say I have watched a ton of your videos but this is the first one I have saved .
Great content
That book is the best thing ever for learning macros!!
Read it cover to cover 10 years ago and I haven't programmed the same since!!
Thanks for helping make understanding macros so easy. Great video! Great job!
This is control specific. Especially with fanuc controls. I highly recommend you read the machine manual AND the yellow fanuc books that come with your machine. With most fanuc controls you'll need a #3000 under your M30 or "end of record" M code.
A lot more simple than I thought it would be! Very cool!
Donnie my favorite guy at titans by far
I program at a job shop with machines that are mostly 35+ years old. Macros and Subs help me keep my programs small enough to fit in the 32k-1024k of program memory I have. Also, I make macros for simple operations so the machinists can punch in a few variables and get stuff like helical plunge operations without bothering me
helical plunging is a waste of time prefer to plunge point for pocketing dynamic. also subroutine G91 G03 I-. Z-. for counter bores much easier to identify, edit, much faster
Awesome video Donnie, I'm still recovering from my workout!
Macros are super useful -keep teaching,it is always good to review
Have fun in Switzerland, I went to Tornos over 20 years ago and bought a couple Decos.
Great video Donnie. Keep ‘em coming
Very interesting video!👍
Great for using same program for multiple sized parts.
Or things like circles or thread mills
GREAT ideas! Thank you!!!
Exactly this. We use this at my work for varying sized parts. Soo much easier having one program to make 20 sizes than 20 programs!
Now that Iv mastered g code… I’m on to learning macros, and boy is it so much more difficult 😂I know 2 people that add their own custom macros for in process inspection and automatic tool changed after life expires and retouch off with tool break detect too, if you ever find guys that can make programs fool proof for lights out like that, pay them in gold and never let them go
I got a 3 axis vertical mill. Fanuc control. With very little memory. I would like to run multiple vises and run more parts without creating longer programs and sometimes you may only be able to setup one or 2 vises. With each vise being assigned G54, G55, G56, etc. Is it possible to write a macro to change the work offset in each tool block to cycle through G54, G55, G56? May make for a informative video? Great job with all your doing! Helping us all means a lot!
There are a few ways to do this, but sticking with what was in the video, you could do the same format, run your program in g54, hit 601, your 1234 takes you to a g55, since that's modal, your program can run assuming you don't have 100 g54s in the way, then 602 takes you to g56. Or something like that. You can sit down and write it out
most fanuc controls can switch the work offset just by typing G54, G55 etc. (that's why they actually called G..)
so the program will be as simple as
G54;
M98 P0001;
G55;
M98 P0001;
...
M30;
extremely informative video, Great episode
Thank you so much for this its really helping Me fill in the gibberish after starting my job as a cnc operator.

yes. marco is very useful. as early as the 6M series, i myself have created quite a variety of marco.
Can we also see some mill applications for macros? I used them on 4 axis mills in a aerospace shop on tombstone type fixtures
Good idea thank you! Will be a great way to show system variables
Excellent video Donnie!
I’d get in trouble if I was caught using the macro part counter back in the day because the supervisor didn’t understand macros and was afraid the machine would crash. LOL “GOTO” on the other hand, was a lifesaver for proving out programs and picking up with where I left off in general.
I’ve also heard you can create your own alarms too! I never had the opportunity to ask the guy who figured it out; probably for the better because you know there would be some witty intent behind it 😆
For part counter there is M54 on fanuc controllers that does just that. On some machines there will be an alarm when you reach the number you want, some other machines don't care and keep going
Can you show a way to write a macro to keep track of time from a cycle start to a cycle start?
I am wanting an easy way to track time per part including setup for billing purposes. The machine (Haas) tells cycle time but I want to easily track part to part time. Trying to stopwatch is a pain 😆
Very useful my knowledge of cnc program
Can we please get a video on how a Swiss machines collet system works so well and clamps well enough to

Great video. Next video you should use the machine time to do an auto power off function!
Donnie the magician introducing us into the dark arts of macro's in programming. :D Well all in all no black magic if you know what you doing, much appreciated to show a glimps of whats going on inside the blackbox for people not that familiar with it or still learning!
Also really nice to throw the whole macro code in the comments!
I'm not a machinist nor do I intend on becoming one, yet I still found this highly enjoyable. ☺️
I did a macro program for a tapered stud for a customer, they called me in to do a new version of the stud about 2 years later, I changed 3 variables and the machine was making parts.

@@donniehinske yes. I work on a 4axis mill on FANUC. Basically I use mostly build in instructions from machine. But i'm curious if it is possible to make a macro for making a circular hole but with spiral toolpath like from cam software. Normally fanuc does it like this. Drop down in pre drilled hole or pocket then it makes a circle then adjust one step into the material and then another circle upsizing hole with each circle by that step u programmed in built in cycle. It would be awesome to do it like from cam where you have constantly increasing diameter in which tooll traverses. With macro i think you can program end diameter you want and then program step of that spiral. It would need to include that incremental instructions but it is hard for me to grasp yet. Sorry for bad english. Thanks for reply love your content ppl and all of it. Best wishes from Poland! BOOM!
@@Yamototamto I see what you are saying. Let me start jumbling that around in my mind and I’ll think of something. I’ve written circular interpolation macros before like you are saying I’ve never had it increase diameter as it does the circular movement (spiral) like you are saying.
It CAN be done though. Nothing is impossible! Stay tuned for a video
@@Yamototamto also… thank you! I am glad you enjoy our videos!!! 😀
Great video. I was pleasantly surprised to see that book, the very same one I got my company to buy me many years back. And I still use it today when I need to reference or refresh my knowledge.
Once I discovered Macro B it was a game changer for many of my had written programs.
Excellent video guys, it's so good that you're showing it off on a Fanuc controller! There are just so many of them out there and macro stuff is super useful. It's just such a shame that Fanuc isn't producing anything similar...
Love this guy. Natural vlogger!
Fan and work, make the production a million times smoother! just cool to be seeing this sessions and love it. Just killing it all the time.
Wow! Great video Donnie! Looking forward to more 👍
Love that book.
Nice job with this video.
Awesome Donnie, I have one for you that I've wanted for quite some time: A macro that can turn really long parts with seamless transitions, no lift just turning all the way to 35" and lets do it in Titanium, I could really use that!
Great video. I'm looking forward to more on this topic. Thanks a mill
How does that work without having end1 and do1 statements? Never seen it done this way. Awesome video thanks
Those statements go into a WHILE statement. This is just IF and GOTO. They work a little differently
Looks like Unix bash shell scripts 😁. Much love and gratitude.
If only G code had the same level of flexibility as BASH but unfortunately it can't even compare to POSIX Shell.
@@Jack-yl7cc exactly. Been using Unix for 32 years now I’m learning g code so at least I have all of the different language structures down. Just need to focus on some manual programming g-code.
Is there any post processor which generates these type of macro logics if commanded
A video I would like to see: Creating your own g codes and incorporating macro variables(like tornos G800/G900). These variables are used in other G codes or you can even create a torx head.
Thank you for the lesson you’re a great teacher!
I'd really like to see a macro that can vary the spindle speed during a cut on a lathe to prevent chatter.
You can do it. I’ve written one in the past, it’s usually dependent on an added variable for the distance travelled before the chatter starts then adjusting the speed up or down as required when it reaches that point. I found it a bit awkward to use in practice because it requires trial and error for each different type of part before they can run in production.
@@Glenrok I think the top level comment is actually talking about a macro that constantly varies cutting speed based on a randomly generated (or a seed generated / function) pattern along the programmed path (whatever that is) around a base value. This should by itself alleviate some chatter issues by itself because it'd break up resonance from building up.
What you seem to be implying is a cutting speed gradient along a path which is a trial and error solution but you can guesstimate from experience a bit sometimes. Something like a 50% slowdown over a 4xD distance for example. My own experience is actually more dealing with extremely long endmills, 6xD+, occasionally had to grab a 10xD here and there to mixed success.
@@xm210c yes, that’s exactly how my macro worked. Either way it would have to effect some change in rpm based on either time or distance- obviously I chose distance for mine. I like your idea of a randomly generated number within a specified range, unfortunately I neither know or can find a function in Macro B which would produce one, so a macro would have to be written just for that which would then be called by the chatter macro. I doubt the maths to do so is beyond me- but it is beyond what I could be bothered to mess around with to find out…….😏
Donnie is such a vibe
Can you please explain to us the principe of ssv spindle speed variation
You miss to tell about #3901's variables which is about workpieces counter. In many cases, when we have a looped workflow we need to deal with that thing
I would love to see a multi tool change based on Useage. Is parts 1-10 on t1, parts 11-20 on t2, … parts 51-60 on t6.
The only way to know if a macro is not being used is to do a deep dive to every program on the machine and check for macros that are being used. Reading the documentation that comes with the machine is a good start, but I ran machines where the machine tool builder book was wrong. On top of that, you don’t know if anyone had dip there fingers in the programs on the machine. I myself will program Marcos that will return the values to null when finished as a safety check to make sure those values can’t be used somewhere else.
With that being said, can you go over the basic concepts to writing programs for probing?
Like how to check for low battery State
Calibration procedures
How to find the safest max feed rate during a non contact move and the fastest feed rate that can be use for a measuring move.
That’s a good idea, but a better idea would be to read and store any value already in the variable, then return it to that value after your macro finishes. That way, if the machine is depending on an already stored variable, it’s not jeopardised from having been returned to null…..
this was actually very educating. thanks a lot.
Yes more videos about macros please
Is 3006=1 work for all the machines or I need to look on manual which one it allows the message not alarm.
We run a ton of macro programs at work it's super convenient
Never use GOTO statement in any code. Yo can learn that in the first year of University. In the next years you can learn it from experience when other try to use it.
Anyway, series of programming CNC I found very productive. Keep it rolling.
If you are programming fanuc cnc it is not easy to avoid GOTO. The IF statements allows the conditional execution of a single macro statement or a conditional GOTO. Therefore if you want to condionally execute a bunch of macro ans cnc lines there are little alternatives. But I agree with you that GOTO should be avoided whenever possible.
WHILE [YOU WORKING] , [ WE ] GOTO [ DRINK A COFFEE ] !
Love to see more information about using macros to interface with the ERP systems.
I had no idea macros were even a thing before your thread macro video, so any video on any macro will be interesting for me. Also, are macros mostly used in swiss machines and production of big quantities of parts?
Macros can be used on almost any CNC machine. Some just may be formatted differently. Any Fanuc control with Macro B will work like this. You just may only have #500-#549 to play with
Macros can be used in a wide variety of lathes and mills. I've created mill macro program to quick write center/drill/tap programs that kick out proper speeds and feeds for simple plates, a single program for making multiple simple bushings per push off our Haas Lathe w/ barfeeder just by entering the desired OD and length, and controlling stock breaks on Swiss machines when for when you find yourself swapping bar sizes every time you run a job. They definitely take a lot of upfront programming and knowledge of what your using them for, but can save a lot of time in the end for shops that find themselves making a lot of simple parts that change sizes with the wind.
@@havokwest4359 when you learn to use a macro, programming becomes easier and the program is clearer and neater when written by hand on a machin. and the advantage is that you seem like God to operators who cannot learn and understand how macro works 😄
I ran a EDM wire 95% of the time using macros. Had it from setting up a pallet of parts, calling programs to set each position, then each program per part. Even had it changing power settings and spark gap for the same program depending on material thickness. All from changing a few numbers. Macros are brilliant and simple for operators to use. I love programming them, the harder the better. Really gets the old brain working lol.
Can you show how you would input the same macro "tool life" for multiple tools that have various tool life. Say od turn rough has 20pcs tool life. Od finish 40pcs. Cutoff 40pcs etc. I feel like your greater to or equal to main count say od turn rough of 20 would have to be in a different area. Or do you just create those macros in tandem with start at say 400 finish 401. But with all tool life? Thanks in advance
You guys produce great content!
What’s the repeatability of that specific tool holder? In the past on various Swiss machines, like a Star, you’d have to pull the whole holder out, touch off, etc m, then make an offset. Just curious
Is it possible to have the screen automatically go back to the program screen when cycle start is pressed after user defined message appears?
Very nice i like your guidelines
Awesome! Excellent video. A macro for compensating work offset with touch probe would be very interesting :D

@@donniehinske I first need to ask for permission to make something like this cause it takes time, and if the machines not running the company losing money
@@donniehinske when we use the macro, we use it so that there is no problem even if the macro is used. for example: if I use #500 to define the offset at the beginning of the tool and another operator overwrites that macro with another variable, it's not a problem because when I start my program, macro #500 is set again to the value I defined. you mentioned that you have a macro of that thread stored next to it. if you defined those macro values in that program, you can later delete or change them without any problem, because the next time you start that threading program, your values will be written again in the macro you use.
cute video, you can also use GOTO to skip over a tool or tools in a program, just in case you have to change the order without bugging your programmer.
Wait,,, I have a program running in a loop, the machine increases the tool count at the m30 so it's not counting. Would I have to write a macro for each tool? Or, does anyone know how to make the machine count the tool usage while in a loop? Mazak 510c nexus mill, thank you for any help or assistance!
Yes you have to add this logic for each tool if you want to do it correctly. Lots of typing at first but when it’s all done it’s worth it
when I use a macro, I use it for each tool separately and I don't define the macro at the beginning of the program, but after changing the tool. I define F with a macro and then use that macro. if the operator needs to correct F, he corrects it immediately at the beginning of the tool and then he does not need to look for it in the program where everything changes the offset ( Milling )
Cool, really well explained.
Where can i buy that book?😊
The book is written by Peter Smid, called FANUC CNC custom macros. It's nearly 20 years old, so you can find some used copies floating around somewhere online. It's also still in print if you want to buy it brand new.
Could download the pdf
I would enjoy and make great use of a video that could probe a bore populate a work offset. I have some parts in my shop that need reworked. The swimgarms for Polaris slingshots lol.
Can you write a sub-macro where it can calculate the amount of travel a particular tool made while cutting and add that up to calculate actual tool wear? Then add that to any similar tool when programming it so you can change it out when it has reached its limit.
Very cool stuff though. Similar to robotics programming, which is my field. 🤙
i'd love to see a macro for siemens, i have a siemens 840d sl controller, and the machine is automated with a robotic arm from ABB, however the camera that sends the coordinates for the part to pick to the robot is not that good. when i use marposs probe i want to be able to limit the probe if i have a part sticking out on the one side for milling it so i don't have to machine my jaws over and over again
Great video..and in fact we really need more tutorial videos about macro program..when I was working in milling machine I tried to understand macro programming many times but I failed...not because it hard..it because I didn't find any one can explain that in easy way and further more there are really few videos in TH-cam talk about this type of programming.

I'm a software engineer. and looking at the Macro programming guide I can see very chaotic style of programming ther. Global variables, goto statements, implicit semantics. AKA a nightmare...
