The best way to know that mach 4 is no good is the fact that the Chinese are not bothering to clone it.
LMAO TRUE!
我也喜欢mach3
underrated comment ... lol i guess mach 3 is still the way to go for your new cnc even in 2024 ? or are there better alternatives ?
Linuxcnc. It was a learning curve, but mach 3 sucks so badly as well. Once I started with Linuxcnc everything else just fell by the wayside.
I would like to try Linux but it looks so difficult to set up. I'm using Mach3 for my plasma table but now converting a conventional mill to cnc did you find it hard to set up?
@@steveu235 Well, kinda, but I knew nothing about Linux whatsoever. So I was learning multiple things at once. Once I got it running on a machine, then just did the stepconf wizard and tried it out. There are some good walkthroughs here on youtube, but it is a learning curve. Feel free to reply here and we can figure out a way I could help you if possible. It really is so much better than Mach once you get it going.
@@steveu235 watch my videos
I'm a week into trying to make Mach4 work on my CNC router and haven't made a single cut. I'm shocked and angry I had to pay TWO HUNDRED dollars for this thing. The GUI alone looks like it was made by a CS student in 1995. In fucking believable
Try UCCNC maybe.
The GUI is rather meh there too, but it actually has a proper trajectory planner.
@@heinzhaupthaar5590 swapping one problem for another. Your getting a hobby interest group developed like product guised as a commercial ready product.
For Windows UCCNC the way. Just one tiny info. When you press stop in UCCNC it pauses immediately and you can continue from there. Try with Mach to press Stop, you can than start from begenning of program
Man I used mac3 for a CNC welder years ago, it was a pain but worked most of the time. I was just about to go down the mach4 road, but having serious second thoughts. Thanks for the reality check.
Centroid acorn unit looks to be a very affordable and nice system
I wanna build myself a CNC machine for wood using Mach3 and the CSMIO/IP-M ethernet controller to have smoother movement and less CPU-intensive stress of your pc for not having to deal with timing on your parallel port. I heard this combo is good enough and stable and reliable. Would this be a good choice?
“Mach4 sucks “ but ... not a word about your setup , hardware , motion card , there are so many things to take in consideration . If you use just a pc and an lpt port , then yes, move to Linux or whatever you think is the best .
I have to add that LINUXCNC!!!
Linux CNC my dude, it's a tuesday.
I know that you suspect the "Ball Nuts", however, did you verify that the "Ball Screw" is properly trapped? Sometimes you need to insert a "wave washer" to ensure that the play is gone.
Been running Mach4 for two years. Works great.
Try a second probe as TLO and the first one as 3d Probe, a lot of problems will occur
currently I have an hobbit machine running GRBL, I want a bit more features, do you suggest me Mach3 instead of mach4 or something else?
As a bunch of people mentioned LinuxCNC with a Mesa control board. It has a learning curve but once you get it you can do anything.
Centroid Acorn. Good people making a great software/hardware solution for CNC control. Works great and very easy to configure.
What did you use for a cylinder for the power draw bar?
This is why I went with Centroid Acorn!
Centroid acorn board here with cnc12. Happy as can be.
Is that a Clearpath motor I see? What is your opinion on those motors? I changed from steppers,,, And really like them !!!
I know you said you're more comfortable in a Windows environment and want a solution that works well in Windows but honestly Linuxcnc might just be the way to go. Same as you, I'm much happier in a Windows environment but I made the switch to Linuxcnc late last year and yeah there was a learning curve, but it's been worth it because, so far, it just... works. Might be something to try out if a better windows option doesn't present itself
Linux cnc and don't look back.
Totally agree. it may be a bit overwhelming at first but once you get the hang of it you won't go back.
How is the response time of Linux CNC? I used Mach 3 before and the response time of my commands seemed terrible
I’m currently setting up LinuxCNC for the first time using an RPi4 with Mesa FPGA cards. A bit overwhelming for a newbie but it’s really cool lol.
@@Thorhian Yes very cool. Rock solid
linux is real time response - but you need good computer
have you thought about trying Linux cnc i have herd that it has a real time kernel mode also i believe that they built a ui that is very similar to path pilot from tormach
Pathpilot is linuxcnc. I believe even heidenhiem is Linux as well. Linux is in everything. I use LinuxCNC and love it.
@@michaelalcocer6778 haas nextgen controller has moved from windows to linux.
.@@michaelalcocer6778
If you heard Linux has a real time kernel then you heard wrong. Because Linux has 4 different real time solutions. I think LinuxCNC supports any of them too?
@@1pcfred not sure where you get your info but linux has had several versions of its real time kernel available for a long time now. A simple search will show this to be true.
backlash:: check your ballscrew bearing pre-load (try increasing it). Check that your gib is not over-tightened (either too far in, or gib screws causing it to bow). PS: using mach 4 for a couple of years now on a PM25, and don't seem to have too much trouble with it. (I'm running on a stripped down win7 instance that is not allowed to do anything else, but run the mill).
Just want to say thanks for your excellent screen set. It makes mach3 a slick, functional controller, especially with a motion controller like UC300ETH!
If you have a UC controller, why not use UCCNC?
It's vastly superior and has a proper trajectory planner.
CV mode works proper too, you can exactly set your tolerances/deviations.
What controller are you using with Mach4?
The chinese double ballnuts have an adjustment in the center of the two I believe.
To the cost of Mach4 I added 450 dollars for a Hicon integra motion controller and it was still disappointing. I switched to centroid, and I couldn’t be happier. Some of my high satisfaction may be because of my previous mach4 experience.
I just buy a mesa board, partition space on my hard drive and dual boot to LinuxCNC. Can have a basic machine up and running in 20 minutes after the wiring is hooked up 👌
Have they improved/Has your opinion changed since this video was posted?
Thank you for bringing up these problems. I was almost ready to buy a new controller for Mach 4.
Just found out you got banned from Mach.... Welcome to LinuxCNC ! :) It does have the most civilized forum, bar none ! BTW, i am tommylight there.
Came here looking for comments about this 👌😂
LinuxCNC has python escape codes and allows you to do your g-code in mathematical equations. Imagine being able to use cylindrical coordinates. Your background is just the kind of background to make maximal use of LinuxCNC. I use Atom based D510 and D525 boards with solid state hard drives. Two parallel ports. One for outputs and one for inputs. One of these days I'll go to the Mesa boards.
You accepted a axis malfunction every week or so? !!!!!! I have not had an axis malfunction in YEARS! And I do update my LinuxCNC installs. I have a 1979 CNC mill running a totally 21'st cen control system.
Am I clueless or is there no video #2? I was doing a Mach series against Pumotix and was about to test mach4 and found this video.
Linux cnc never failed me I wel not the software part
So, just to make sure that I've followed this correctly, you were using Mach 4 with a SmoothStepper and you were having problems? Ethernet or USB interface? And now you're using Mach 3 with the same SmoothStepper and it works OK? Great videos of the ballscrew conversion etc. BTW. :-) Linuxcnc seems to be getting a lot of support on here, Fagor in Spain make commercial CNC controllers and they have Linux under the skin. Linuxcnc has a proper real-time OS, unlike Mach 3, which has this "driver hack thing" which somehow allows Mach 3 access to Ring 0 in the Windows OS, very clever IMO but if you don't have access to Windows source code, how do you know this sort of thing is going to work properly ALL of the time? Or am I wrong about any or all of this?
I was going to say what do you care what OS your machine controller runs on but so many people in the comments already said use LinuxCNC that I kind of feel redundant. Anyways, just use LinuxCNC you goof.
Keyboard Shortcuts are not gone, they are still available and can be modified. The big problem with the softlimits is a big true. But you can change the ref home script for auto enabling after homing. 8:40min is she showing th-cam.com/video/IXuuGRACU1I/w-d-xo.html
Hi, What Clearpaths are you running, Thanks
I switched to Acorn a year ago because I got tired of Mach4's crap!!!
Or one of Centroid's other boards...
does acorn support xyz probing? or just z?
@@fga55 XYZ, it’s very diverse
I have been trying for about 3 YEARS to configure Mach 4 to my ESS and Gecko G540 controller mated to my Sherline Mill with ZERO luck and let me tell you, I've also reached out and emailed the company asking for help, yeah Id get better response from the I.R.S. on getting a refund on a Sunday morning. WOuld you happen to know and or recommend better easier to use software now that ive thrown $250 down a toilet?
Can you use EtherCat servos and drivers
Software developer here, so I can commiserate with the challenges of writing good software. But Mach4 is really awful. Flaky enough that you never actually trust it which is not what you want on a spinny metal cutter of barely-contained destruction. A few issues I've personally had in recent weeks:
- sometimes won't home correctly (homes one or two of the axis and stops, reporting success)
- slight jog sometimes makes it perform a full travel inexplicably until you mash disable
- probing occasionally drills into table after probing is done (two broken tips because of this, before I realized what was going on)
- losing or resetting tool offsets after tool change. Makes every automatic toolchange exciting!
- the list goes on and on and on
Documentation is nonexistent. Plugin and script editing is a hot mess in a proprietary built-in editor, weird global macro scopes interact with local macros in unpredictable ways, screen editor straight from 1997 visual basic, non-presence on their own forums (presumably so you buy the industrial version). Did I mention no documentation?
Sorry Mach folks, it really is trash. I tried to give it a chance since I assumed negative comments were from people who didn't like moving from Mach3...but no, it's just bad. I'm also moving away as soon as I find some time, will probably "downgrade" to Mach3 in the meantime as well. Blah
Try Linuxcnc
Try UCCNC and not having to learn all the LinuxCNC stuff...
@@heinzhaupthaar5590 He said documentation is a problem, imagine when he gets to uccnc non documentation, lol.
I have the problem with ATC also ,it goes to tools 3 for example and load it on the turret but after a while DRO show tool 8 or 1 without doing any tool change ,I wonder why
I use mach4 industrial. I do have issues with the latest versions. I just roll back to the previous stable build. Sucks youve had so many issues.
It is not great... been tuning my motors and when I go back into configuration to adjust "Counts Per Unit", the Velocity, Acceleration, and backlash values are changed to something totally different! Velocity changes from 80 Units/Min to 1000! What the f#%$?!
Is the .004 in the balls/ballscrew or dose the ballscrew need a preload between your tapper bearings, may just need an extra shim or two, you mentioned using tapper rollers in your build video, may just be a run-in issue now its had time to run and settle.
You are a spitting image of Mike from the Mike and Lauren channel. It's uncanny!
Mach 4 has been nearly ready for 15 years!
Thx for the new screen set, really appreciate the work, but I can't make a donation until i get it working. I was able to download it and actually see the new screen set, but non ofthe buttons show up. What did I do wrong, what am I missing I copied and pasted the bitmap and the PA set to the Mach3 folder, but no luck on seeing everything I need to see. Can you help my fellow cnc-er. Thanks for any help provided.
Holy cow just figured it out! Thx - now I can provide a donation.
Have you set the ''USB Selective Suspend'' to disabled?
(no idea if you even have the controller connected over USB)
The setting is under Advanced Power Options in Windows.
I use Acorn centroid CNC12.
What is your opinion on UCCNC?
Dude, while Mach4 isn't perfect, I just want to point out errors with your point of view:
1) Your very first point about macros and functionality not copying over sounded like an issue with your motion controller, or your profile plugin... but you blamed Mach4 instead. You could have mentioned exactly which motion board it was to help others, but you refrained from those details.
2) There are dozens of videos, documentation, and hundreds of forum threads indicating that Mach4 (a lot like LinuxCNC), requires a ton of customization and some knowledge of coding or scripting in order to get it to do certain things. These aren't HAAS or Fanuc controllers with machines they can use for standardizing. They left it open for YOU to have that flexibility since everybody's DIY machine is different. You could go with Centroid or Masso, but then you will have creative limitations in what you can do beyond what the developers setup for you.
3) You make a lot of assumptions about surface-level things. Mach4 being buggy and unpredictable, changing your windows OS 3 times, the interface. Just proves that this software wasn't right for you. How Mach4's core API, macros, subroutines, GUI, and LUA all tie together is deeper than "good" or "bad". It all comes down to how you manipulate the scripts. Literally people have retrofitted industrial VMC's with side arm tool changers using Mach4, because they know what they're doing, or were willing to learn.
I will admit. The technical support for Hobby License is horrendous. They are only willing to offer in-depth support for Industrial License users, but hey, that's what the community is for. How you ended the video is more appropriate. "I didn't ask for help because I got discouraged", is something you should lead with. It's easier to publicly trash something and claim it sucks instead of admitting that you don't understand it. I know it's an old video but you came off really condescending here and it's not a good look.
You really should check out UCCNC from cncdrive.
Using Mach 3 for years It just sucked so much, that I ended up buying a stand alone offline controller. It works great. It’s an SMC5-5-S-S
I switched to UCCNC wit a UC300ETH and UB1 board.
Not the cheapest possible solution but it's been working great and having an actual CV mode with exactly definable deviations is worth a lot if you're using a faster linear guide machine.
What settings does the trajectory planner got in those stand alone units?
Can you slave an Axis to a master one if one axis has 2 motors ?
Did anyone mention linux cnc yet?
This post does not make a mention of the motion controller used.
exact comment I was going to make..
Backlash on the Z axis. Seems impossible. Specially with all that weight. Probably a bigger issue.
U r possibly missing the. 004 from the motor not being set right or drive train.
look intoo the centroid acorn
the driverboard is pricey (300 dollar for the kit with power supply all the cables and gubbins ) but the software is free or 160 dollar for the pro version , both versions are based of professional software made for people running cnc machines in a factory setup and run under windows
they allso have great support and a dedicated forum
i cant belive tis wrong video is suggested when searching mach4
I found it hard to connect any controllers to my computer without a serial port. So instead I use a smoothieboard. It costs about €100 and you can hook up steppers to it directly if they are small. Otherwise you connect big stepper drivers. It reads and executes G-Code files and you can control it over USB using the free software Prontr Face. So the smoothieboard actually handles all the cutting.
Its very simple, but it works. You only need to remember a few commands like @abort G92 for setting 0 and /playSD:toolpath.txt You can also create Macros. So instead of typing 10 lines of text into the command line, you can save them and just enter “MakroToEjectPart” for example.
All the machine setup is saved on the smoothieboard. Like acceleration and maximum feeds. You cannot loose that stuff.
They recently had a Kickstarter for Version 2 and I ordered one already. They will ship in a few months. You can also build 4 or 5 axis machines and hook up sensors, endstops, pumps or heaters for 3D printing.
One of the best ways to go is to get a Mesa FPGA board or two and use LinuxCNC. Smoothie isn’t terrible though.
Mach 4 sucks, ended up moving to mesa + linuxcnc and haven't had any issues yet
I wouldn't blame Windows as opposed to Mach 4. Using Mach 3, I had a cut with over 300,000 lines off code and did it with Windows 7 just a few months ago.
Can you adjust the backlash compensation in mach 4? I can do this on my tormach.!!
That's as basic as it gets, everything can do that.
"did that, 3 times"
Dang!
Linux cnc and you be happy.
I'll add another plug for Centroid if anyone is thinking about going down the CNC conversion route. I just finished doing a conversion with it and it's been incredibility hassle free.
If you are trying to track down where that backlash is coming from, don't discount the bearings you are using. Or the other components in the system. Put a 10ths indicator on parts and see what's moving. If the motor is turning, that energy is going somewhere. Axial play in the whole ball screw could indicate slop in the bearings. Movement in things like bearing blocks or radial movement in the ball screw could be acting like a spring in the system. They will have to be unwound and tensioned again before the axis moves in the other direction.
With my Deckel Fp41 with cnc2301 ......... I have NEVER had an axis stopping during machining ever because of software problems in 15 years......
Friend of my had an Aciera fp550 with Fanuc ,year of build 1987....that was programming HORROR...... The whole software / programming needed all kind of rules , when not applied it would not run without error codes given why not. He once used 3 hours figuring out that you could not mill a hole of 10mm diameter with an 8 mm end mill...... Why not??? Because the Fanuc cnc was programmed needing at least 1 mm or more to move from center of the hole to the outside.....But that was nowhere written in the program manual.....If death penalties would be there for CNC machines...that one would be sentenced ...... Or if you would not have a desire commiting suicide ...that old Fanuc cnc would get you there despite the shiploads of Prozac taken each day!!!!!
why not acorn cnc?
To many glitches for me, I have mach 3 on a plasma table and would never attempt to try and run it with a cnc mill.
Mine freezes, stops doesn't fire and other stuff about 4 times a day. Most of the time I can just start over and run over the old cut but sometimes I lose a sheet of steel to it. I don't think it's so much mach 3 but the compatible to different computers. Lot of it is my fault but then you add the glitch mach 3 and 4 are known for and its hard to keep things going and make money.
I think I'm going to go with Masso next. Right now my biggest problem is my torch will follow the steel fine with the thc and go below the touch off point to catch the warped steel, but if it's a long cut at some time it stops Going below the touch off point. So if a thin piece of steel warps below the water level I will miss the cut.
i like the retro look of Mach 3
Funny :) I wish you've tried Linux CNC :(
What do you guys think of Acorn CNC from Centroid? The controller and software it comes with seem interesting to me
sounds like an electrical problem , maybe a loose wire?
MACH3 was REALLY bad, there was some two button keystroke for jogging...and WHEN u did it in the wrong order it would jog and keep jogging til it crashed or hit a limit...That is inexcusable,I don't have faith in a provider who would not fix that.
Oh, but that's a feature lol.
Never saw that... There's the arrow keys for jog and shift+arrow for jog at maximum rapid speed (which I guess is what you mean for "two-button keystroke"). If messing with the shift key makes the arrow key stuck then I'd blame the keyboard before the software. The only thing remotely similar to this is that if you press the arrow key before shift then it won't suddenly start rapiding when the shift key goes down, which is completely expected behavior for a modifier key.
@@johanstrom8473 I have my jog set to 5 or 10% so without shift it moves slow; you have to deliberately hold shift to fast jog, so no mistakes (Mach3). But I like it, but appreciate all the input against Mach4 and toward LinuxCNC and Acorn.
vondeliusc that's exactly how it works normally, I'm not sure what problems people have with it!
Here is a fun example of what at least one controller lets you do, and some other controllers don't. If you can run custom code in a realtime thread, using the live spindle position as input, you can do things like this:
th-cam.com/video/PtD9w6lp8n8/w-d-xo.html
Last weekend I used the same principles on my lathe to thread a tap with the proper radial relief angles.
naaaaaa!!!! incredible stuff!!
UCCNC is the way to go!
So *that’s* where the dev team from Quark Xpress ended up...
I’m not a software developer and don’t ever want to be. The latest build is 4612 and needs a lot of attention when you get it. Mine was just terrible. Then I thought what about other versions. So I downloaded AVID CNCs version. It worked immediately out of the box lots of stuff fixed in that version for me anyway. It might help someone else. Now Mach 4 just might stay. Thanks AVID.
I switched from Mach to UCCNC I can automate many peripherals (unlimited really) with it because of serial modbus capability, great value and great support. Interface is via windows but real time tasks are handled by the controller. It's not like the (VERY) old days where some systems tried to do real time within the PC. I recommend the UC300EHT and UB1 combination.
running into hard stops, call technic, im 99% sure you can set soft limits in the clearpath servo software , if you crashed the cnc it might be why you have backlash.
Huh..... my Mach4 machine runs awesome..... maybe it's the operator
I believe I downloaded the SDK for MACH 3 10 or 15 years ago. I would search for it in my pile of hard disks and usb drives if someone like Physics anonymous would work with me to fix the issues that cause me problems. I like MACH 3 but the pendant interface sucks. Ive never got it to work right. I know everyone hates LPT ports. I am old! They work just fine for me and I just wanted to get my simple projects to work in MACH 3...Its simple...I like it
it is illegal to both sell a beta version and sell unstable software ( unstable software is technically classified as a potential a virus)
Get Acorn CNC12 from Centroid and you will run your machine in few hours!
RE: Soul Searching: Typically, the "Stable Version" of software is NOT the latest version. It's the version that's been proven to be stable with few if any critical bugs.
But generally it's not 4 or 5 versions old. It should at the most be two 0.0.1 versions back. Otherwise it means you are ignoring known bugs when you build new versions
Why can't the unexpected stops be a hardware issue?
Because I have had none of these problems with Mach 3, same hardware, same windows install.
lol. I found this video while trying to fix some issues I have with MACH4, let me tell you guys starting out. spend the money on good software and hardware, smoothsteper and mach3 got me started for sure, but its limited, its was old, so I upgraded to mach4. Well that was a waste of 200 and hours of aggravation, no support, forget the forums, people on there seem to be programing experts that just reply like it's normal for MACH4 not to work and you are supposed to find a work around yourself. It's absolute garbage. working on getting hardware now for linuxcnc, or maybe another professional level app.
7:34 Could use my A-hole to crimp sleeves onto cables
So how much money was dumped into that crap?
I dumped $6000 once into a used Deckel CNC with glass scales and nice control and it's working ever since, without much work. Just don't understand how one could spend that much money/effort into something like that and get shit results, if you can simply buy a really nice secondhand machine and have a mostly problem free time afterwards, along with the excellent quality that most professional machines have.
If you find a good one, not some worn out pile with electrical gremlins :)
Did your Deckel have a Grundig or Heidenhain control?
I've had nothing but issues with Mach 3 and was going to tell New Fangled to give me Mach 4 but now listening to you I may just piss all MACH's in the friggen garbage bin. That's where it belongs. Anyone know of a highly reliable alternative that can run with Fusion 360 and CNC Controller NOVUSUN I'd be a very happy man
Lol... I know this is an old post but
you're complaining about running Mach4 off of a NOVOSUN controller off of F360? NOVOSUN is complete and utter garbage. Use a smoothstepper for reliability. I haven't used many functions on my CNC router, but once Mach3 (which is what I use) was setup, I have never had to do anything for it to run smoothly (except I use windows 10 so sometimes an update screws me over). I probably shouldn't have updates going but meh. I'll take the risk.
So maybe mach has some problems but seriously, Its been incredibly stable for me.
Are you sure it is backlash and not end float?
Exactly my centiment
Use a custom windows install. Strip out all the bullshit . Use msmg toolkit and remove just about everything. Especially and including updates. You don’t need them on a dedicated machine pc. Just don’t open any email attachments or visit shady websites.
u can try eding cnc
i use it, it just works.
Used Eding a bit on a router. It is stable, but the interface is poor and fonctions are not easy to set up and require macros. Plus, the pendant os very expensive.
2:35 - Oh god lol 🤣I already knew these hyped CNC softwares are only for hobby people but not for processional minded.
I want to decide what should I buy Mach3 or Mach4. I got a SmoothStepper controller, so I have to chose one of MachX.
I wanted to buy Mach4, because the Mach3 looks really aged SW and most probably it is indeed. Then I've found this video on youtube.
OK but this is actually just a rant, you show us nothing, you tell nothing specific, you tell no details. In the next part you don talk about Mach4 anymore, you show us your Mach3 interface. Hmmm.
Can you show me another similar rant, or an angry Mach4 user here on youtube. Are you alone ? I tried "Mach4 fail", "Mach4 error", "Mach4 problem". Would you please recommend a better search term. Or maybe nobody else can see the truth only you ? I want to believe you just I need more proof.
PS: your Mach3 UI is very nice.
OK, you don't need to answer. I insvestigated the theme. I've found the opposite what you are saying. Most of people think that Mach4 is much better than Mach3. I've found even a toppic about it www.machsupport.com/forum/index.php?topic=42891.0 .
Here is an answer to my question:
"Mach3 was an intuitive to use piece of software, that was aimed at the hobbyist and as such was incredibly popular. Mach4 is a functionally improved piece of software, that is written to allow much greater versatility than Mach3. Mach4 follows far more of the conventions that are associated with commercial CNC controllers.
Sadly using Mach4 involves a steep learning curve from Mach3, which many users do not want to undertake."
So not the Mach4 sucks but you. You can't set something without reading the manual, and then instead of reading the manual you start cursing on youtube. You don't want to learn it, you want it to work without that. I don't understand why was so hard to set soft limits, they have uploaded a video about it th-cam.com/video/IXuuGRACU1I/w-d-xo.html
+78 for Linux
I moved to uccnc network control and no problems I ran match 3 for years but match 4 is crap
Customer service by the vendor is atrocious. That alone is a good reason not to use the product.
Centroid acorn cnc.
th-cam.com/video/IXuuGRACU1I/w-d-xo.html at 8:40min you can Copy the script and mach4 enables the softlimits after homing automatically!
