Hello,

I am posting on behalf of my grandfather who recently replaced his old CNC for hobbying with a China CNCZone 6090. We are trying to configure the Zero Tool, as that is the last major piece he needs before he can continue hobby workshopping, but we are having some issues with the probe.

We are using the probe that came with the machine, but are not seeing the Digitize or Probe lights show up in the Diagnostics screen when we touch them together. We have tried a multitude of pins and ports, toggling active low, run a continuity test on the probe, and even reinstalling Mach3, but none appear to be working. We have also tried multiple different variations of Zero code from sources that have shown it working.

I should note, we are using the RnRMotionControllerECO-V2.0 Drivers to connect a laptop running WindowsXP to the controller box with USB instead of Parallel.

Anyone have any ideas for how to proceed? The continuity test makes me believe it is not a physical or hardware issue, and that maybe we have something configured incorrectly within Mach3.

The China CNCZone website shows a different machine listed as the 6090 now, so their manual has been updated for the new machine over the old one.

If you have any suggestions, please let me know and I would be happy to give them a shot.

Thank you.

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?

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!
