Mach3 & G31, again

Postby Alberto FUL » Tue Apr 11, 2017 2:09 pm

MAch 3 Version R3.043.066, UC300ETH, V1.008, C61
Still have problems with probing. It seems that G31 does not work very well at slow speed. I had a lot of problems probing at relatively slow feed-rate (let say 100 mm/min). Sometimes the axis (X and Z, not probing simultaeously) soon after triggering probe, jump at high speed few mm away, often loosing steps. I tried different speed, acceleration, debounce interval with no significant results. I noticed that the slower speed the more often I get the problem. So I tried dramatically faster probing speed, like 1600 mm/min: no more loosing steps but, off course, less accurate probing. Have now 3 machines running exactly same code and parameters, they have all same problem. I have an older machine with UC300USB and I had no problem at any probing spedd. Can You check, please ?
