Description

I've made changes to Klipper on my SKR Pico according to instructions herein and checked the wiring and the probe deploys and stows but never shows as triggered. The probe deploys using the Probe_Delpoy macro but doesn't retract when touched lightly with a fingernail. On attempting to home the probe does nothing and the carriage crashes into the bed.

All previous efforts with the BL Touch, CR Touch, 3D Touch and IR Differential probes all failed. So I switched to the Microprobe as it is from the same manufacturer as my Pico, in the false hope that they should work better together.

After weeks of messing with hardware from this manufacturer I'm not inclined to do carry on doing testing they should have done and will just return both the Microprobe and Pico as unfit for purpose, if this issue is not resolved quickly.

Research direction

No files or tests are named. Start by reproducing the setup with the SKR Pico and Microprobe, then inspect the Klipper configuration and Probe_Delpoy macro alongside the stated wiring and homing behavior. Done means the probe reports triggered when touched and homing stops safely.
