Had a successful calibration of 0.70, but was stuck with an error regarding the SD card code not starting.
In another thread, Bar mentioned this could have to do with the yaml file.
I grabbed a fresh copy, put it on my machine, went to calibrate, and now the bottom right arm is giving slack when pushing in rather than when pulling out.
Retract All ran just fine.
This persists after restarting the circuit board.
Going to try replacing it again and seeing how that goes.
