thanks for making this incredible open source project, I am occupying the AR3 robot in a coffee machine however, J6 performs the calibration without touching the limit switch and does not return to its rest position. This problem does not always occur, it happens every 2 or 3 calibration routines. I have already checked and replaced the limit switch, check teensy's connections, and disable de encoders but the issue is still there, so any help is welcome again thank you very much
