I updated my original post, but I wanted to reiterate here as well:

There is a new build of Mach3 3.043.062 on our website (machsupport.com) which includes a patch that fixes this issue. Install this version over your previous version, restart, and you should be back in business. As always, I recommend backing up your important Mach3 files: profile(s), license, and any custom macros or screens you may have. It's always better to err on the side of caution.


There is a product that we call Expert, but it is not something that we have tested or are prepared to support at this time. It is still under development but it will have the ability to run two "instances" of Mach within a single version with M code hand shakes going back and forth to prevent collisions. Such a set up would require two separate motion controllers (in this case, two Galils).


It looks like KB4054518 is an old update (December 2017) that may have been replaced by the two I mentioned before (KB4093118 and KB4103718). I'll hang on to it in my notes in case others are the same boat as you, coming online and getting slammed with updates.

Thank you,

Thank you for sharing. I will add that update to my list. So far, KB4093118 and KB4103718 have also caused the same issue with the parallel port.


Edit: June's KB284826 update also causes crashes for parallel port users.

Thank you for sharing that, Malcolm. I installed the May updates on our Windows 7 testing pc overnight and will be doing some testing today. I suspected that update would be the culprit again this month and you have confirmed my suspicion.


Someone at CNC Zone did some testing and it appears that Mach3 still works in 32 bit versions of Windows 10. It may be only 64 bit versions where Mach3 no longer works.

That's good to know! I don't know if we have any Windows 10 32 bit systems to test with, but I will find out and try it out. Thank you!

Is this update a problem for Mach4 users?

This feature update did not affect Mach4. Mach3 uses .dll files in its plugins and this new update made it so those types of files are no longer allowed. Mach4 was developed according to newer security standards and runs fine on Windows 10 version 1803.

This is a basic video showing you how to roll back the Windows 10 feature update that is affecting Mach3: https://youtu.be/KKhve2qPPCU

General Mach Discussion / Mach3 Windows 10 update -- don't do it

Hello all,

It was brought to our attention today that a new Windows 10 update is causing problems with Mach3. Microsoft is certainly causing me a lot of headaches this past month, but I hope this post will save you from some. If Windows 10 wants to do a "feature update" to version 1803 do not let it. You want to stay on build 1709. If the update goes through and you find that Mach3 will not load beyond the splash screen, the update probably went through and you'll have to roll it back. It's an easy process but it is a bit time consuming. Go into your settings and find the Updates page. Click 'View installed update history' then 'Recovery options.' That sounds a bit dramatic; you're really just rolling back to a slightly older version of Windows 10. On the next screen, you'll have the option to restore Windows 10 to an older version. Agree to the prompts and then be prepared to wait while your system un-updates.

As always, we recommend running Mach3 without automatic updates and offline if at all possible. I'll keep you posted with any new information I might have.

Happy CNCing,

Update: There is a new Mach3 installer on our website (machsupport.com) that includes a patched version of .062 that corrects this issue. Install it over your previous version of Mach3, restart, and you should be back to normal. As always, I recommend backing up your profile, license, and any custom macros or screens--just in case.
