Hi guys, just received licence so now can test extended programs, kool! Have encountered some issues tho... I have experimented with individual axes and find I can run
them pretty damn hard, 1500mm/min at 1000 pulse per mm. Steppers get hot at that speed. Backed off the motor current to bout 3/4 rated and slowed rapids to
600mm/min, ie 10kHz. Because I am using 10:1 reduction have got torque to burn, dont stick your finger in it, will rip it off and look for the arm!
My problems start when I do coordinated moves.
Sounded initally like a bad bearing or tooth off a gear, had me worried. I stripped down and checked yet again. The screws and rails etc are all second hand but all
originally top spec items and no mechanical issues I can detect nor any pattern to the intermittant glitch. Occassionally the glitch would precipitate a stall.
I beleive now my computer is at fault, ie occasionally the pulse train goes offline, 'glitch', and if when pulses return the accel is too steep, stall.
Can anyone suggest likley programs or processes running on my computer that are likely culprits? I dont have antivirus installed, reckon the antivirus stuff buggers up my
computer worse than a virus!
