I have been trying to figure this out for hours.
I have been searching this forum, google and cnczone, and have found no answers.
I have a renshaw probe set up on my 3 axis bridgeport, i have it running through a SS breakout board, a Smooth stepper and in to mach 3. The probe is functional. I can get the diagnostics "digitize" led to light when i manually touch the probe.
first I tried the wizzard for digitize and the Z never drops (with G31) to touch the item im digitizing. Then I tried the digitizing plugin, but I get a strange error. much searching has led me to believe that the plugin cannot be used with current version of mach 3.
So, I went back to the wizzard thinking it was the settings I was entering into it. no such luck. more googleing led me to test if G31 was working in MDI. I tried it a dozen times in MDI and the machine and mach DRO does not move with the G31 command. i tried it for x, y and z, G31 does nothing. no machine movement, no dro changes etc...
All this leads me to believe that for some reason G31 does not work. I have searched for hours, checked my settings over and over, and I cant figure out how to get G31 to work.
I hope someone here can help. I sure could use it.
