Hey i understand him. I think you want a switch for the different length of your nozzles. I am searching for the same thing.

This is a good way to start. He use parallel the bltouch. So it is a second z endstop.
Thanks for all replies.
I will do it like @dc42 dc42 said. Which one do you prefere?
Sorry for the late reply. I had a lot of work to do.
Free are Fan 1 and 8. Pwm 1-4 have free sockets, but the heater sockets are used. Pwm5 have a bltouch connected.
Maybe use Fan 1 and 8 for switching the gnd or 5v of the servo and bltouch on/off. Then use the same pwm signal of PWM5? Is this possible?
Bltouch and the servo for toolchange is not often used.
Hello,
i need a Servo for my Tool0. Problem is all PWM Pins are used on the Duet2 Ethernet and the Duex5. On PWM5 is the Bltouch. Where i can get a Pwm Signal for the Servo. I thought Fan8 can have a Pwm Signal, but it is not possible.
Other idea is to use the servo and the bltouch both on pwm5 and made there powersupply switchable.
Maybe have someone a better solution?
Thanks Mo
