using BLtouch when using Duet Breakout Expansion Board
I have a Duet Wifi (3.1.1) where I added a expansion breakout board for external stepper drivers.
I have reached the limitation of missing pins multiple times right now:
- When I want to make an emergency button to activate M112
- When I want to use a BL touch.
I already have the expansion breakout board and need it for my external stepper drivers. Since the board uses a 50 pin cable, the pins within are not useable anymore.
Is there a way to combine the expansion breakout board and still have these options?
Thanks in advance
You still have access to the heater6 and heater7 pins.
@Phaedrux Can I use those for an end stop and/or an emergency button? If so, how do I put this in my config code correctly?
For the emergency stop you would configure M581
M581 P"exp.heater7" T0 C0
I think that should work.
@Phaedrux Thanks, can I use my heater6 or heater7 pins for my BLtouch endstop?
Yes you could use the heater pins for the bltouch servo control, 5v, and ground connection. The trigger signal would still need to return to the mainboard.
