If it happens on both platforms that suggests to me it is not the software which is the issue ,
I have changed both leads so they should not be the problem. Breakout is CNC4you, KK01 with 5 volt supply via usb.
I dont think it is the microstepper driver wiring cos the problem occurs on different motions, rather than any particular one.

So where do I go from here??????????
I would pull all the wiring and check the lot.
Then if it's broke fix it and reinstall. Should eliminate any possible wiring defect.

You could try another board too if you really wanted to. You can get one similar to the KK for less than £10.
Same as the one I have ran for 3 years (£5 at the time).
