BIQU MicroProbe V2.0 on Spider with Klipper?

General Discussion
40

Klipper does not detect a toggling pin. It seems that the pin is always triggered and does not change.

If I understand the working of this probe correctly then the process should be:

  1. Probe pin is reported open
  2. Probe_Deploy is called → The probe’s tip gets extended
  3. The probe touches the bed
  4. The probe pin toggles “triggered” → Klipper notices the endstop signal
  5. Probe_Stow is called and the tip gets retracted again
  6. Probe pin is reported open again

This is run twice. When either #1 or #4 or #6 does not work correctly then you will either receive No trigger on [X / Y / Z] after full movement or the error in your screenshot.

This could be due to some wrong wiring / wrong pin assignment or due to the “pull-up” topic discussed above.
