I'm having problems with my mills spindle speed controller and hope some one might be able to help me sort it.
I have nearly no electronics experience so please be gentle
What's happing is while turning the speed up or down the revs are all over the place. In mid range settings the spindle will rev up and down and on occasions stop completely.
Its never been good from the day I got it and I should have sorted it while on warranty but it seems to be getting worse or my tolerance levels are decreasing as the machine gets closer to the scrap yard.
It does have some adjustable things inside namely (blue in pic) IR, CL, max revs, min revs and acceleration. Hopefully its just one of these that needs a tweak?
Any one?
