Hello all!
I have a smaller machine that has a set of 3 Keling KL23H276-30-8B steppers on it.
I recently started doing some different machining that's requiring more speed than I usually run, but a problem that's always existed has now come back to bite me. Since I got the machine, it's always had this little glitch. You'll be jogging an axis, and as it goes along, it will suddenly make a very short 'stalling' sound, for lack of a better term. Normally the axis will continue on its way happily, but now I've been trying to ramp up the speeds and when it hits these 'spots', the axis starts losing steps (axis stops, whining noise from stepper like it's stuck)
This can happen on any axis, and in any location on the axis, however it seems to usually happen in the middle area, as if it's determined by how long the motor has been running. Unfortunately, the controller is some generic thing that doesn't appear to have brand name on it.
Anyway, I've been scouring the forums, and tried tons of tricks I've read, but can't get this to go away. As far as I can tell, it's not mechanical, everything moves nice an free, no binding. I'm running a 3.0ghz pentium desktop with nothing installed but mach and windows xp, though it's entirely possible it's the pc causing the problem I suppose, I have no proof either way.
I'm kind of at a loss here. The steppers seem to sail along flawlessly at high speed other than these glitches. I know I haven't covered all the bases as far as testing goes, but I thought I'd ask here, hopefully you guys can save me some time.
TYIA ~
