hello,

lately, I've been fiddling with my power supply, and when i connected to the printer the first time after working on the PSU, my XYZ motion became very laggy:
I meat it seams as if its ramming something, but on all three axis, or as if it tries to skip a bunch of steps

does anybody knows what could be causing this?

What exactly did you fiddle with on your power supply ?

A video would probably help show what the issue is, it doesn't sound like the easiest thing to explain in words.
