Mach4 General Discussion / Mach 4 Probing issue - "Can't transition from MDI running to stop."

« on: June 25, 2018, 01:08:52 PM »

So I have been trying to setup probing with Mach 4 using a contact probe, but I cannot even get the calibration routines to complete without getting the error message: "Can't transition from MDI running to stop." I am using a probe from drewtronics (https://drewtronics.org/s5000led) and a PMDX-424 board on a retrofitted Bridgeport M-Head. I have confirmed that Mach 4 is seeing the probe, as the indicator on the touch module does trigger when I contact something with the probe. The probe itself also has an LED indicator that turns on when contacting something. I am seeing this behavior in both the touch module and the probing screen set. Anyone else run into this problem?
