MachPro General Discussion / Re: ESS Spindle Setup

« Last post by Sunkistist on July 17, 2026, 02:44:44 PM »

Yes, sorry I assumed the MB3 which is the only BOB I'm familiar with. But either way I think all the BOBs have the 10v analog out for spindle control so that remains a viable test strategy right? Also, the plugin portion for the ESS in Machpro would be the same regardless of the BOB right? Genuine question, not a push back, I'm here to learn too. I guess we need to confirm if OP has set it up digitally in MachPro the way it was working in Mach4.

I'd be hesitant to share my ini since I'm wrestling with other problems but I'd recommend looking at your spindle tab in the ESS plugin settings. One thing I noticed right after I migrated was that the spindle settings hadn't been merged into the new MachPro profile. Mach had the default 60hz in the PWM version for spindle control and my VFD/ESS likes 260 Hz, at least for my TECO L510. Next thing I'd look for is what is the spindle speed output signal mapped to in the ESS plugin, I used the standard 0-10v analog dedicated for spindle control and it seems to work fine. After that I would check the spindle speeds in the Mach config settings... after I migrated I had to tweak the table similar to what these instructions say.

One quick sanity check would be to do an M3 S500 or something and then measure the voltage on the ESS analog pins (assuming thats how you're controlling the VFD), then change the speed to say... double what you first chose and see what the new voltage is. If the voltage doesn't follow the M3 commands then it would suggest the VFD doesn't have anything to do with the problem and it's either the ESS or Mach.

It won't be the ESS with analog pins. It's the bob attached to the ESS. I use C25XP from cnc4pc which has a analog 10v output for the spindle control. along with 2 relays for forward/reverse and a PWM signal.

General Mach Discussion / Re: Newbie trying to get Mach3 Configured

« Last post by fluterly on July 16, 2026, 12:22:40 PM »

Doesn't seem like my images attached.  And doesn't seem like I have the ability to attach images whenever I try to so I am going to try uploading them via 3rd party.





I have the xml file which I will try attaching but that doesn't seem to work when I preview.

I have mostly gotten the xyz stuff working, just got it homing.  But still have had no luck on the spindle start/stop.

Thanks.

Depends on your spindle vfd and how it was setup. I have a hungyuang vfd with for/rev and spindle at speed.. I have both mach4 and MachPro. Both work.

MachPro General Discussion / ESS Spindle Setup

« Last post by lmarti13 on July 15, 2026, 08:48:38 PM »

Does anyone have a working ESS/Mach Pro spindle setup that they would be willing to share?  I migrated from an ESS v275 Mach4 installation to Mach Pro and cannot get my spindle to work.  I know that ESS v278+ made a change in spindle configuration, but I cannot figure it out.

Thanks for the help.

Mach4 General Discussion / Re: RTCP for a XYZCA (five axes) CNC

Hi Andy,
VERY KOOL INDEED!!!

I look forward with anticipation.

Do you have any thoughts on how you would market it? Would it for instance be included as standard or would you market it as an add-on?
I imagine that releasing it into the hobby market could and most probably would garner a huge demand for support. Do you have any thoughts on how you'd deal with that?

As I've posted in this thread, and other threads on this board, I am willing to pay serious money for RTCP.

I am not especially inclined to subscription software however I've been forced to change my mind as a result of my experience with Fusion. I've come to realise that a subscription allows me
to have access to good, if not industry leading, software which I could not afford to buy a perpetual license outright. One of the corollaries of a subscription model in the the manufacturer gets
a modest but recurring income stream. I'm not overly concerned about supporting Autodesk, but for a vastly smaller organization like MachLabs then a recurring income stream could be
a gamechanger. Other hobbyists might whinge and moan about that prospect, but I on the other hand see that if an organisation or company has a steady income then that same company
with a secure future path to advance and support better products............to my benefit!  If I want Mach4 to continue to grow and evolve in capability and performance then it is incumbent on
me and others to pay for that, its just how the world works.

Craig,

We are working on adding RTCP into MachPro.  I would expect we will have it out within the next 6 months.

General Mach Discussion / Re: CNC plasma Mach 3 torch height controller issues

« Last post by historyhunter on July 14, 2026, 11:27:39 PM »

I greatly appreciate the information provided here on the CNC plasma torch height controller issues. In similar instances, I've found it helpful to double-check my machine's grounding; a poor ground can cause unpredictable height adjustments. Has anyone tried calibrating their THC settings with various materials?

Thanks Colten,

I renamed, and recompiled the file and was able to map mcTouchOff to the button. Now I get the touch off that I was used to.
