Hi all, It turned out to be the end-stops micro switches causing the board to lose connection. I read up on the on "Connecting endstop switches - What might go wrong" and then I corrected the wiring and all is good with that.

Now I need to figure out what is causing my X and Y axis make a continuous "ta ta ta..." sound (like a machine gun), while jumping back about several mm then to a stop when it triggers the end-stop; only when I Home All and individually home the Y axis, but the X axis behaves normal in when I home individually.

Any ideas?

Thank you all for your help.

Jumping solved! Did a new RepRap Config at RRF, there may have been a error in my part on the first RRF config.

Please closed this as solved.

Thanks.

@Phaedrux Sorry for getting back late, I was out on a business trip.

For the Duet2 WIFI, the current was set to 1A and ran without issues, but I understand it has different drivers and beside the fact it's older, nonetheless it worked.

No issues with other axis.

I changed the motor drive current to all the axis to 80% of motor mA specs, but that didn't change the behavior, as it the extruder motor still shuddered when commanded to extrude.

Although after enabling StealthChop it is now extruding. To verify, I have power-cycled the printer multiple times and now when I run an M302 P1 it extrudes and printed a 20mm cube without issues.

Issue RESOLVED!

Thank you for the support!
