Hey guys I have a custom M6 macro which has been working for about a year, i recently upgraded Mach 4 and ESS (likely not following best practices) and now the same M6 does not work the same, my Z does not even move and Mach 4 gives message "ESS Starting Probe 0" and system is stuck at this point.
I also had the functionality to adjust the X & Y location along with feed rate for probe move and probe thickness offset easily by going to Mach 4 top left menu -> diagnostic -> Regfile - New fangled Solutions and a popup would pop up where the above variables were listed with the option of editing, now when i do the same nothing opens up... i feel like i shot myself in the leg.
M6:
