- How I start my Fanuc OM based CNC Mill. How to get started or use an older Fanuc OM based mill. I purchased a used CNC mill and have been using it successfully for over a year. For DIY type operation, it's been reliable and capable. Excel VMC mills, in particular, seem to be very reliable, easy to work on and I've been able to source parts. I use Fusion 360 along with custom post-processing to my DNC to make parts. The oil absorbers I use are at: amzn.to/2CGWHbu
Zebra skimmer works great. Easy maintenance.
Good to know! Thanks!
I sometimes add / (block delete) in front of M08:
/M08
Then you can turn block delete on when you don't want your program to control coolant.
I usually just use Notepad, and Search/Replace M08 with /M08.
Thats a great idea. Thank you!
Try Notepad++. You can set the "style" to pitch black so you don't look at a white screen constantly. I made a g-code config so most commands have their own color code for ease of use. I can send you the settings file if you like?
I've been really enjoying Houghton HoCut 795MD. I don't have an RO or a skimmer yet, but I do have a fish tank aerator bubbler thing submerged in the sump and that keeps the coolant kinda agitated and aerated.
Fanuc internals are bomb proof yeah you might need to change the screen or keys 🎹 but that’s it run for 20 years easy that’s running hard 24/7
Thank you so much. It is as you say.
Welcome!
excel..ent vid, your vids have really helped me get my 810 up and running.
Having recently invested in a Tschorn 3D probe I felt it a backward step to then do calculations for working out my offsets.
below is a macro prog I knocked up for locating a corner just as you described.
simply call it from memory and move first axis ( in this case its X ) to required position by HANDLE mode then switch to AUTO and press Cycle start. The code will run to prog stop at which point you switch back to HANDLE and position the 2nd ( Y ) and 3rd ( Z ) axis switching back to AUTO running the Code up to next prog stop each time.
Start program from the N1, N2...… Line depending on which WCP your wanting to set.
Also did a similar macro for center finding if anyone is interested.

P.S. please don't be to hard on my writing style. 18 month ago I had never used G code and had no idea how it worked, now I own 3 CNC's and just have to keep learning.
Nice! I have a newer fanuc that has operator message which makes it easier to come back too running macros with manual input. I wish the older OM had it.
I’m glad I’m not the only one that writes important thing on the face of my machines lol
I rarely have seen others do it but I have done that for years. Can't loose or forget it if it's right in front of you.
I keep a China marker right on top of the control.
I bought a skimpy oil skimmer and just leave it run all the time. Also the Blasser swisslube synergy 735 has been working very well in my mill.
That's great to hear. I'm about to switch.
If your machine is on the home switch on those 0M controls you should be able to select Zero return and hit the Minus button and the slide will move off and home automatically. I would write a macro and assign it to the M6 command so you don't have to use program space to do all the housekeeping involved in a tool change. This machine uses P0737 G30 for the tool change height. de WA1AIM
Yeah, for home I just hit each axis with the + or - to auto home. For me, I just added the tool change macro into my post process. I'm always drip-feeding from the DNC so space isn't an issue. The machine does have a macro saved I did for any setup work that does the tool offset on a change. I set it up for M66.
I have a mill with a Fanuc 0md control. I tried your tip to walk off the home switches, because it would have been very handy, but unfortunately it doesn't work for me. I guess I have the poverty model mill that doesn't have this feature. Dangit.
Hello, thank you for the educational videos
I use anderson fancu cnc every day quite simple once you figure them out
Hi Shane, I have a Excel 510 with Fanuc 0-M control, it sat for a couple of years and lost its parameters. I got in touch with Kiwa and the sent me the parameter sheet for my machine but it was missing the 01-380 parameters, also on the diagnostic parameters at 300-549, the paper work they sent me shows its suppose to be 00020000 but when I put that in its instantly puts a 1 in place of the 2.
I have been able to zero return the machine, but haven't had any success on tool changes and spindle start. I feel I may be missing some parameters. any help would be great.
also my tool changer is a side mount
Thanks
Derek
On tool change do you know if it had a 9001 program macro? Most of the 510's did. Most map to M66 for tool change. Otherwise you have to manually orient the spindle and Z in post.
@@ShaneBurrell1 my parameters stop at 8399 I do not have the 1800 parameters either
can you email me what your params are right now? My email is easy to locate.
@@ShaneBurrell1 I must not be looking in the right spots. Lol. I can’t find it.
I found it, I just sent you an email. Thanks Shane
great video , a bit above my head but very good
Where did you get new screen from?
Ebay.
hello , I need your help with Fanuc 6m for tool offset and work offset
Is it a 6mb?
@@ShaneBurrell1 my control is fanuc system 6m year 1980 please send me an email maquinados@industriassim.com.mx
I'm getting a lot better on this OM control, but stuck on figuring out how to do cutter compensation with it?
Which option does you OM have?
@@ShaneBurrell1 Option? I am not sure, it didn't come with an original manual, I know the tool offsets only have the z column and no place to put tool diameter.
@@markbradfield219 The OM has a few different cutter compensation options. Most only have the H but those can normally be used as well for cutter comp if your tool count is low and you have the portions avail.
@@ShaneBurrell1 OK, thanks, I gave up trying to get it going today and went back to programming the actual cutter path! I'll figure it out eventually! Lol
Shane, great videos!
I just purchased a used Excel 510 a few weeka ago and am not sure how to do a simple thing like "Load the tools into the Automatic Tool Changer" (ATC). I have loaded a few tools into my ATC-18 by simply "snapping them into the ATC, but I am not sure that is the correct way to install tools. When I give the command to get tool 1 ("T1 M6"), it goes to tool 11. You mentioned that the tools get put back into whatever slot is available, so could it be that the previous owner of the mill put tool #1 into slot 1 but the machine ended up placing it into slot 11 "because it was available"? I have looked for a video or instructions about "How to Load an "Automatic Tool Changer" but have not found one yet. Is the "right way" to load the tools into the spindle and have the spindle move it into the ATC? If so, how should it be done?
Thanks! The best way to load the machine is to use the tool change command and do the tool change in the spindle. Pulling pots (unless the pots are labeled correctly) doesn't work normally because the tool number sticks with the pots and has nothing to do with the slot number in carousel. Really the only time I manually snap the pots in or out is to replace a broken tool. Even then I normally do that from the spindle to set tool height at the same time. The alternate way, which big job shops use, is to label slots on carousel and label pots with tool number. They they will actually go into the machine params as they manually load pots into slots and change the param table for pot to slot assignment. I have several videos on the ATC and on one of them I show the param change method. You will need to do this as well if you ever get your carousel out of index. I believe it would have been the carousel air cylinder repair video I did.
fanuc series O-M I have problem . Alarm 409 ?
ipiubelli I would need a lot more info to help. 409 is normally a servo error.
@@ShaneBurrell1 normale 409 and the servo error is 56
Any update on your 409 fix?
Great video. I have a similar Excel machine that also has the leaking oil cylinder on the drawbar pneumatic cylinder. Do you happen to have the link for the one you used as a replacement? Thanks
It should be a SMC. Grab the model number off the cylinder and SMC (orange coast pneumatics) will be able to cross reference it with current product. All my cylinders they cross referenced and matched as a direct replacement.
Great video shane, I have an older EMCO PC Turn 155 Lathe that runs on WinNC Fanuc 21 controls, what DNC are you using and how is that setup? I may want to try and connect one on my EMCO
I'm using a titan DNS. It just requires matching the baud rate and comm settings.
@@ShaneBurrell1 Thanks, ill let you know how it goes. Where is that Excel mill from btw? Germany?
Mine was made in Japan. Also BT40 tooling.
Hello I saw your video on that titandnc adapter and I got it but unfortunately I have no manual for my machine I have no tape or remote mode on my machine I have a 1998 Mori seiki fm-1 with a MSC-521 controller which is I believe a fanuc 21m series and I’m having a hard time trying to drip feed Just wondering if you have a tip for me to get it to drip feed .
Thank you
Danny Esparza If you have found a rs-232 port check you opr panel screen. There are a few other ways but normally if no rmt or tape they hide it on opr panel. If it’s not there you can find Fanuc 21 manual and set dnc mode from a param.
can I git your help with my machine or can you direct me to where I can I get help thank you much
Any CNC tech in your area should be able to help. If you have a specific question I might be able to answer it.
Where did you find the box for translating/converting the USB input to the RS232 port? What is that box called?
Maybe I found it... "TITAN DNC USB Reader for CNC Machines" ?
Thats it. There are several vendors that sell these.
Hey I can’t seem to get my okk mcv 410 to tool change. I followed your procedure and copied your tool change program but it just alarms out with cycle can’t start
My machine was built by excel. Yours is likely vastly different than mine especially in the tool change. Do you have the manual? Does it have any 9000 programs?
@@ShaneBurrell1 no it doesn’t have any 9000 programs
Great and Useful video! Do you know what format the GCODE is that the FANUC reads and what profile to use in Fusion 360 to export the cut paths correctly?
Thanks,
Brady
The standard fanuc post worked on my machine other than the tool change which is a simple edit of the post. I needed to position the Z before the M tool change in the post code.
@@ShaneBurrell1 Ok thanks! I'm using a Makino machine from the 90s with what seems to be the same Fanuc system as yours. We are using dnc4U on the computer to send the GCODE over to the machine. Just to clarify the Post in Fusion you are using is as follows, Vendor:Fanuc, Description:FANUC. Is that correct?
Thanks again,
Brady
That is correct.
@@ShaneBurrell1 Cool! One last question. Is there a way to set a custom home position instead of just the zeroed out position?
@@bradybrother100 My machine zero is not adjustable.
Does that 232 usb dnc adapter work fast enough for HSM programs?
Generally, yes. It generally comes up as a limitation on the control side not having the higher baud options.
@@ShaneBurrell1 I am looking at a 18m machine with a highest baud rate of 19,200. Is that fast enough?
Vince Dahl I do 3D hsm at that speed with the fanuc. A lot depends on the controller. If you want to test prior to buying a dnc there is software on the internet you could use to act as a dnc.
How to view the program line in dnc mode
You have to look at it on the DNC or file editor.
whats that box on the side that you're plugging your usb drive into?
DNC Usb / Serial
DNC? Is that something you added?
@@shaunybonny688 It is a add on.
Hi. Maybe someone could help me. I need Fanuc Ladder II program but cant find that. Maybe someone could share if you have it? Thank you.
You will need to get that from a Fanuc tech.
Thank you for answer. Already done. Still nothing . One more question. I have Leadwell TDC-510 - Fanuc O-M RoboDrill Tool Change CNC milling machine. And seems that part of code is missing cause tool change is not working. I need tool change macros I suppose. Maybe you have one and could share please? Best is to have the same, but in worst case I could use other macros as basic and write new one
If your machine is like mine it needs to be oriented prior to the tool change. You can do this in a macro on in your post processor.
@@ShaneBurrell1 yes, I understand about macros and tried to write it manually but failed cause I have no idea how it should be written right. Some samples what I found are totally wrong in my case. Looks like from model to model there were used very different codes. As I had no backup and have no manuals left for this machine I have no idea how it should be. Without any sample it is very tricky business. Of cource trying different options will work after some time but it will take long time...
@@user-ws6bm2ri1d Leadwell seems to still be in business. Have you tried contacting them? Also if that's you asking in the CNC forums, that also a good place to happen along someone that has the same machine with macros. www.leadwell.com.tw
Does Fanuc O-M support the DNC mode? Because the ROM memory is too low that I cannot upload G-Code above 16 kb.
If equipped yes.
@@ShaneBurrell1 I sent you an e-mail. Can you check?
I did receive your email and posting response here so it may help others.
I have several videos on it. I'll post those in the comments at youtube as it may help others. If you have a tape mode and a working DB9 or DB25 serial interface a DNC will work. If not, you would have to likely add tape mode to the machine (if possible).

Hello
Can I get some help with my fanuc 0m
I will help if I can.
Yes the Parameters are very important. I have a Fanuc OM as well and the parameters were erased. I have re entered the Parameters and Diagnostic numbers and the machine is working but the ATC does not. I'm wondering if you can send me a copy of the Ladder diagram? I'm willing to pay for them for your time. I do have a service book with most of the ladder diagrams but there are a few pages missing, i suspect some of the ATC ladder diagrams are missing.
To program the ladder you would likely need the fanuc ladder program.
@UCE8e-YGXqHRrKl0ejJSjwGg I would love to know which post processor you are using in Fusion for the Fanuc OM control. Is it the generic Fanuc post processor? Have you tweaked it at all? I am having trouble with the post processors Fusion provides.
I added tool change to the stock Fanuc post processor.
@@ShaneBurrell1 Shane you beautiful bastard, can you post that? I'd love to have a copy of a working post processor. Thanks.
@@joels7605 Autodesk doesn't allow posting of there posts but it's pretty trivial to edit the existing Fanuc post. Just open with your favorite editor and look for tool change. It's pretty simple to add the command steps for your particular machine.
@@ShaneBurrell1 I'll have a look. Thanks.
Can i go in MDI and punch in M6 T4 ?
Yes you can.
@@ShaneBurrell1 thanks Shane. You've been very generous with your help.
This is probably a bit of a dumb question but, I just recently loaded a simple command from my pc to my Leadeell mill. M3 just as a coms test.
Question is how do I pull up that program or command on my machine?
@@toranacar You will need to select / open the program in edit and run in auto once selected.
@@ShaneBurrell1 thanks Shane.
I'll have to back up a little because the program doesn't seem to be loading onto my cnc.
So it's a Fanuc OM.
I thinknfirst I need to ask what comms cable you're using, Null modem or full handshake?
I thinkni need to look at Baud rate on the CNC ?
Just wondering what else I need to look at to load programs.
I can't even Punch a peogram to PC.
I do have LSK flashing.
@@toranacar You will need a cable that has RTS/CTS .
