@PDBeal A note has been added to M308 regarding the limit of 32 sensors. Sorry you have to discover that through trial and error.

@felix9t said in How to free up a specific pin (RRF 3):

Ok I quickly found the solution myself: I had to free up the pin from the Y axis even though I didn't assign the endstop to it:

M574 Y0 P"nil"

I'm glad you solved it. See https://duet3d.dozuki.com/Wiki/RepRapFirmware_3_overview#Section_Default_pin_assignments for the default pin assignments.

@dc42 Thanks for the last update. It solved one issue with the BLTouch v3.
The biggest problem I had was that I needed to invert both pins from:

M950 S4 C"exp.heater4" ... M950 S0 C"exp.heater3"

to

M950 S4 C"!exp.heater4" ... M950 S0 C"!exp.heater3"

That solved all issues. I've just discovered that they needed to be inverted for PWM.. 🙂

The debugPrintf function prints message to USB. it may cause a watchdog timeout if there is no PC connected via USB to receive the message.

@felix9t I have fallen over these things in the beginning too!
