Hi all,
I am having an issue with an old Techno machine that is now running off a Gecko G540. It will quite often stall during toolchanging, but jogs around happily. I have tried various Kernal speeds (using a Dell P4 2.4, 2G RAM). I've tried the Sherline mode. I've tried 0-5 Pulsing on step and dir. I've tried disabling the driver watchdog (because I do get the watchdog error occasionally - especially on the bad stalls). Motors are tuned as follows:
X = Steps/Per 10666 (pretty sure this is correct) 70 to 120 in/min, accel = 9.1 in/min
Y = Steps/Per 10666 (pretty sure this is correct) 70 to 120 in/min, accel = 9.1 in/min
Z = Steps/Per 10666 (pretty sure this is correct) 50 to 70 in/min, accel = 9.1 in/min
Interestingly, a relay box is occasionally also slow to respond. Attached is a vid of the problem - this time on the Z-axis.
