 G201 Opto-Isolator problem, Missed steps | |
I replaced the bad opto-isolator in the Y axis (Z opto moved to Y during last test).
It went both directions after the replacement, but missed steps.
I replaced the replacement (had bought 10) and it still was missing steps (and growling). I replaced bearings on either end of the screw drive, because it sounded like a bad bearing, even though I could not believe a bearing would wait and go out right then just to make my day miserable.
Nope, still missing steps and growling.
Set the pulse width in the motor tuning to 4 us, works fine now.
hmmmmm, could the 512 in front of the 512-HCPL-2531 mean it is only good to 512k instead of 1024k (1mhz)? |
