Hello community,
I have encountered a problem that i simply can not get my head around. I have tried multiple solutions and the step by step guide; https://betrue3d.dk/bltouch-on-duet-wifi-duetreprapfirmware/.
The BLTouch i acting strange. I can perform a G29, a probe-test; M280 P3 S120 I1 and the BLT works as intended. However, when I want to print a part, with the following start g-code (after successfully doing the Auto Delta Calibration);
G28 ; Home
G29 S1 ; Load mesh from previous
I does not work. The effector moves towards the bed followed by a BLTouch that "clicks" (needle touches the bed). The probe does not retract and ends up going into alarm mode. I have checked the wiring twice and everything is fine. I do not know what is wrong i have tried different modes (Mode/Type of probe) P3, P5 and P9. White the same problem.
I have cleaned the pin in the BLT.
I have attached the following settings:
