what version of Mach3 are you using?
(other than that I'm out of ideas).
Version R3.043.062
what is the code you are using if it`s not coded for you screen it wont work to well put it in code tag's
I'm running the 2010 screenset.
Like I said before I'm totally new to all this, especially the electronics part. A little back story here. I bought a Chinese machine with an AKZ250 motion controller card, set up the auto zero probe with an external power supply (9 volt battery) and it worked, and then one day it didn't. I swapped out the AKZ250 card for an ESS/C25 combo and the auto zero still didn't work, played around with it, re calibrated the motor tuning and it started working, just not consistently. I moved the touch plate grnd lead from the front of the table to up onto the spindle mounting plate and the auto zero stopped working. Now if I were reading this I would think that this would be a noise issue because now one of the probe leads is running past another stepper motor and a spindle however I believe there is pretty good noise suppression on the C25 board and I'm running 5v through 2 2.2k res in series to the touch plate. What I am thinking now is that there is a grnd loop issue because the auto zero macro runs as it should when the C25 probe leads/touch plate is isolated from the table, spindle, tool, and doesn't when the grnd lead from the C25 is touching the table, spindle, tool. Does this make sense? If this is indeed a grounding issue how would I go about fixing it, or even testing it beyond the test I've done?
