first off, im new. my problem started with no movement anywhere! after running a small project with no issues.
my set up is a 4x4 cnc mx4660 driver rps48910 power 4- nema 23 570 oz. steppers
(2 motors on Y) 3 kw spindle.
i have replaced the mx4660 and power after burning out both. not sure how it happened.
so im looking at a shunt regulator as this seems to be the fix i keep finding? any thouhts or suggestions on the cause or solution would be great.
