Hi +Ray Kholodovsky,

I rewired my bltouch signalpin from pin 2.4 to pin 1.20 and everything works as expected if motors are disabled (M18).

But as soon as i turn the motors on (M17) nothing happens, when I send M280 S3.0 (push pin down) on the bltouch until I send (M18), then the pin deploys.

It looks to me as if the bltouch does not get signal when motors enabled.

Here is al Link to my config.txt:

Can you try a different pin also?

+Ray Kholodovsky I will go with an rc servo and endstop now to get finished with the machine. This combination works even when motors enabled.

I will give the bltouch another try some time in the future. I want to see the machine running now;-)
