@dc42 said in Servo on a Duet 2 Wifi + Duex5:

280 P0 S100

Ok, sorry to come back to this post so late but I had other issues and I could not test further...

Now I managed to free other 3 heater ports on the Duex, so I got rid of the buck converter as I could connect all 4 servos to 4 pwm ports on the Duet.
Nothing works anymore.

I tried also this configuration but nothing... The only visible thing that happens when I invoke a M42 or M280 command is that the corresponding heater led lights up (and remains up). So, it could be that the ports do not deliver the 5v? Before, using only the signal pin they worked with an external 5v supply...

Can you go through these troubleshooting steps and see how far you can get?

That message is coming from a user macro and not the firmware. What did you push before you got that message?

Hardware seems functional. For further help you'll have to provide some config files. config.g, homeall.g, homex homey homez bed.g and results of M98 P"config.g".
