Hi!
I can’t seem to get the BLTouch sensor to work. My custom wiring for the BLTouch sensor seems to be fine since it worked well with Marlin.
Powering on the machine the bltouch does the self-test fine dropping the probe needle twice, then sending the following commands:
BLTOUCH_DEBUG COMMAND=pin_down
drops the bltouch needle and the bltouch becomes blue
pushing the needle up it locks the needle in for a few mS turning on a red LED in the bltouch, then it drops back down. But if i hold the needle in and sending a QUERY_PROBE it shows triggered in the console.
If I home all axis, after the x and y axes have homed and are positioned at the middle of the print bed, the z axis starts travelling upwards and when I push the bltouch needle up nothing happens, the z axis keeps travelling upwards, it doesn’t stop.
Also, when I click home all axes the z axis moves down a bit when the bed is already at the lowest point, which leads the z axis stepper to miss steps as it cannot go down any further, but this already happened for some reason when I had Marlin flashed on this printer’s board before..
I attached the klippy.log as well as the printer.cfg
I’m fairly new to klipper and don’t know why klipper isn’t being triggered by the bltouch..
Thank you in advance for any help!
