Rewired Printer, Stall homing no longer works

Fickert

So I am a bit confused but at the same time I think I can guess my problem. Curious on other peoples' thoughts.

I finally got all my parts printed and began to rewire my printer and fully assemble it (Please ignore the huge power leads, have new wire coming for that). Before this everything was working perfectly fine. Stall homing, in particular was working great for the X and Y.

I shortened the wires and repinned them, now with the printer fully assembled everything is working just like it should, EXCEPT the stall homing on the X and Y. When I home it immediately stall detects its position.

My guess is my crimps are either better or worse than before (The stepper wires were the standard JST connector originally I plugged into the board to get the setup running, now it is with the Duet connectors and pins)

I quickly messed with the S value in my script, bumping it from 4 to 5 and changed the jog speed but that did not do anything. I didn't have time to diagnose more unfortunately.

I won't have much time to be around the printer but just looking for suggestions to try when I get back Monday.

Photos below because its finally just about all together (PTFE cable chain is all that is left)

Cheers!

Two things:

In your homing files, use G1 H2 commands to move the axes at least one full step away form the physical endstops before you execute the homing move. This resets the status to not-stalled if they were stalled to begin with.
If that doesn't help, try increasing the S parameter (stall detection threshold) a little in your M915 commands.
