General Mach Discussion / Re: Motion controller with analogue outputs

« Last post by Charlie_M on December 20, 2025, 06:37:26 AM »

Have a look at CNC drive motion controllers. I have the uc100 and the eth400 and have not had issues with either. you can use the uccnc software or there  is a plugin for mach3. you can ask questions on the forum to make sure it will do what you want.

General Mach Discussion / Re: Motion controller with analogue outputs

A lot of drives have both 10-0-10 volt input called analogue and also TTL step and direction input you need to find or check the manual for the drives you have.

If the drives can take TTL(0-5V) then any mach3 breakout board can drive the machine.

Sometimes you need to tell the drive the input type but some detect is automatically.

General Mach Discussion / Re: Spindle trips limit switch on every Gcode start

« Last post by Graham Waterworth on December 19, 2025, 09:53:08 PM »

Turn off safe Z move and make sure your initialisation string is something like "G20/G21" inch/metric plus " G40 G00 G90 G99 G43 G80 G54"

 This should be a safe start.

General Mach Discussion / Spindle trips limit switch on every Gcode start

« Last post by alchantelois on December 19, 2025, 04:37:46 PM »

I'm trying to get my machine up and running again after replacing the computer.  I have it mostly set but still have an issue.
Every time I try to run G-code, the spindle moves up (in the Z-axis direction) until it hits the limit switch and then it stops.  There is no code in my G-code telling it to do that so it must be a machine configuration setting, but I don't know what setting needs to be changed.  Any help?

Is it better using a touch monitor like 15.6"? Any problems with Mach4 UI?

Thanks,

Third party software and hardware support forums. / Re: Replacing my Novusun controller with other brand

Thank you Tweakie and Arturo for your replies. I will do my researches to see which one would be best for me.

I didn't know mach 3 was obsolescent, I thought it was a program that was older but kind of "works good so we keep it like that", guess I'll do researches to learn mach 4 too.

Thanks again!!!

Mach4 General Discussion / Re: Need some guidance on Mach3->Mach4 conversion

Well, I figured out both problems and I now have a working configuration.

I am still dumbfounded by this, but somehow (and I am sure it's my fault and I am missing something), the slave axis is configured as "Motor 3" in the pins config menu, but I have to select "Motor 4" (which is not configured in the pins menu at all!!) and it works.  Somewhere I have something crossed I am sure, but for now, it's working.

As for the WHB04-4 pendant.  I removed ALL the third party/extra plugin files.  I enabled JUST the native XHC plugin that came with Mach4.  Once that was enabled, configured, and setup right, the pendants worked fine (both my wired and wireless). Tried that originally but I couldn't get it to "see" the MPG.  I must have done something wrong the first time around as it's all good now!

I now have a fully functioning machine, so off the convert all my VB scripts to LUA and I'll be set.  Thanks to all that looked over my post.

General Mach Discussion / Re: Mach3 stops the CNC, loses origin, don't run again...

« Last post by ben_mtl on December 18, 2025, 11:11:26 AM »

OK, if anyone has the same issue I think I found the problem : the vacuum system !

When I had the issue, one thing I didn't realized instantly is I just installed a new cyclone, the Oneida Dust Deputy 5".
At some point I had to move it and I took a shock.. static electricity. It never happened to me with my old DIY vacuum setup.
I didn't know how to get rid of that static so I just installed my old system.

After hours of research it looks like it's almost a classic with the Oneida but I don't know what I will do and when... even if the Oneida thing was ways more effective than my DIY setup.

Since I went back to my old setup : no static on the hoses, nor on the DIY cyclone, no issue.

The nice thing about what you are doing is that you can install both systems simultaneously and slowly set up and test each feature until all is good.

The issue you are reporting about the MPG appears to be related to the USB drivers or installation, but it seems to be working ok in Mach3, so it has to be the Plugin not talking to the unit.  I understand Brian Barker wrote that plugin and also that it is not working well with the units that are currently being shipped, and the plugin may need an upgrade.
