BLTouch + additional servo

Computiger

I´m trying to set an servo for my tool changer (something like Prusa MMU) but the config for servo isn´t that easy for me.

My Setup:
Duet Wifi
Duex5
BLTouch
miniServo

BLTouch is running for Z-probe and connected to Heater 5 of duex5
the servo I´d like to control is connected to Heater 4 of duex5

The BLTouch is running in z probe w/o any issues but the other servo doesn´t move if I want

M950 S0 C"duex.pwm5"                    ; create servo pin 0 for BLTouch (default from Config Tool)
M950 S1 C"duex.pwm4"                    ; additional servo

I guess my thinking isn´t correct. Please help me to understand how it works

How are you trying to command movement of the additional servo?

Computiger

like this over command line:

M280 P1 S150

using that servo
Savox SC-0254MG

Do you really mean Heater 4, or do you mean PWM4 ?

I mean PWM4

I´ve just tried two other servo´s, these ones run fine like accepted.
They are much cheaper than the 1st one. I have to check the wire.

Thanks
