Hello.
I'm new in the Duet 3 environment and I have a problem with my BLTouch.
The symptoms are: When I turn on the printer and start a job everything works fine. But when I want to start another job, the G32 command in the startup sequence of my job does not eject the pin of the BLTouch. To start the job I have to make a hard reset of the Duet 3 board. After reset it works normal again.
I have tried almost everything I can think of, changed the IO pin, replaced the BLTouch, modified the homexyz macros and so on.
In this and other forums I found similar topics, but no solution for my problem.
Here my environment:
