G31 command stops since moving to Ethernet SmoothStepper

G31 command stops since moving to Ethernet SmoothStepper

I have a z-height and center finding macro I have run for many years that make use of the G31 command. They failed when I moved to my ESS and after some trouble shooting I discovered the G31 command is no longer working. Even when entered as a MIDI command noting happens, For example, G31 Z1 F10.

I have done some searching here and found a few similar observations but without a definitive solution.

The probe LED does work via the diagnostic page as expected

Please refer to the image for wiring of my probe port.

Mach3 versions tested are below and I have also tested from a Dell Laptop and HP Thin client both running Windows 10.

Mach3 Version R3.043.062
Mach3 Version R3.043.066

ESS Version: ESS 2019_02_25 10w2a-10f1

G31 does not move and axis as a midi command however G32 work just fine.


Any help would be appreciated... Thx.

What does your code look like?

I know that several hundred ESS users are using my 2010 screenset, which uses a lot of G31 moves in macros.

I have simplified my troubleshooting by focusing on the G31 command via the MIDI interface.

Something as simple as "G31 Z1 F10", G31 X1 F10 or G31 Y1 F10 does not move any axis.

However any G32 command like G32 Z1 F10 works as expected.

What is G32?
