Mach4 General Discussion / Re: page up, page down for z axis not working

« Last post by PolyTrackk on August 06, 2026, 02:41:36 AM »

I ran into the same thing after moving Mach4 to a newer laptop. Everything else worked fine, but Page Up/Page Down wouldn't jog the Z axis until I checked the keyboard input assignments. It turned out to be a keyboard mapping issue rather than anything with the machine.

General Mach Discussion / Re: Mach3 Zero Tool

« Last post by cuddlysmithing on August 06, 2026, 01:45:29 AM »

Because the RnRMotion USB controller handles inputs through its own plugin, changing Mach3’s standard Ports and Pins settings may not affect the probe. Check the RnRMotion plugin configuration and connect the probe between the correct input terminal and controller GND, then verify the input voltage changes when they touch—a continuity test alone does not confirm that Mach3 is receiving the signal. If the controller input changes but the Digitize LED does not, reinstall the correct ECO-V2.0 plugin/driver and map that input to Digitize.

General Mach Discussion / Help needed with Mach 3 and spindle control

« Last post by Paladin1324 on August 04, 2026, 01:50:28 PM »

I have a Blue Elephant 1325 3 axis router and Mach 3 software. Connection to the XHC controller board in the cabinet is by USB cable and the installation came with the wrong (I assume older) version of the ncusbpod.dll plugin. I downloaded updated version from XHCs website, and now the Mach 3 software is talking to the machine, but I only really have control of the X,Y, and Z on the table. The spindle immediately spools up as soon as I open Mach 3...to what appears to be the minimum 6000 RPM (as set on the VFD) of the 6kW liquid cooled motor. I can change spindle speeds by typing, say "M3 S12000", but I can never stop the spindle. "M5" is completely ineffective. Only way to stop it is by closing Mach 3 or pushing "STOP / RESET" on the 7.5kW Fuling / Fulinn motor VFD.

I've tried getting help from various AI outlets but I get taken for a long loop that never goes anywhere or solves the problem. Is this a port / pins setting issue?

Any help would be greatly appreciated.

Hey Vandel,

Thanks for your response. We worry about cracking open the controller box, as it has a sticker that seems to serve as a marker so the company will know if we open the box.

Do you have any recommendations for generic USB drivers that we can test with?

Unfortunately, the company did not send us a good manual, so we were hoping to exhaust all possible software options before we move forward with cracking the box open.

Please let me know!

Thanks again!

Since the Probe/Digitize LED never changes, I'd focus on the controller rather than the zeroing script. The probe itself sounds OK if it passes a continuity test.

I'd verify that the RnRMotionController ECO plugin supports the Probe input and that the correct input pin is configured in Mach3. If possible, try shorting the probe input directly at the controller. If the LED still doesn't respond, it's likely a controller or plugin configuration issue rather than the probe.

Have you checked whether the controller documentation specifies a dedicated Probe input instead of using the standard Mach3 pin settings?
