I recently installed a BLTouch V3.1 sensor on my CR-10S pro. I used the "Tiny Machines" latest firmware.
When I turn on the printer the BLTouch self tests and turns red. When I go to "Auto Leveling" it tries to do homing and the BLTouch retracts a couple times then finally the pin pushes down and stays that way and lights up blue. From there homing stops; it seems and the Z-axis stays high up without trying to touch the bed while the BLTouch light stays blue and pin down. Every time I go back and forth between that screen the same thing happens. I've gone all the way back to an inductive capacitor and the printer still works how it should. Is the BLTouch bad?
