BTT SKR V1.4 Turbo BLTouch non-responsive #412

Open bsg6867 opened 4 years ago

bsg6867 commented 4 years ago

The setup I have is: Machine: Ender 3 Pro Main board: BTT SKRV1.4 Turbo Accessories: BLTouch Smart Firware: Marlin Bugfix 2.0.x (downloaded ~15 days ago)

Sensorless homing works perfect in X and Y, but the BLTouch does nothing to stop the Z axis from crashing in to the bed.

I swapped 2 of the wires on the 3 pin connector, tried the probe and z axis end stop ports and nothing changes. I've used the probe port and the z axis stop port, as well as swapping the wires in both of those spots.

I've tried reading through other issues that seem the same, but none of the fixes have worked for me

Attached are my configuration.h and configuration_adv.h files

Any help is much appreciated! Marlin_Configs.zip

A quick question, you mentioned that you use sensorless homing in x and y. So my question is did you maybe also left the pin for stallguard intact (uncut/unbend) on the z axis driver? If so the endstop connector is bridged for sensorless homing.
