Ciao,
I have precompiled Marlin firmware installed on a printer Prusa i3 and would like to add couple of servos.
From what I understand I need to install a jumper on the 5V left pin of reset button and than the servos on right pins on reset button.
Now to test if servos works I use the following g-code:
M42 P11 S255 ; power ON servo 0 on pin D11
M280 P0 S90 ; set servo 0 to rest position
nothing happen!
My guess is that since I did not compile the firmware, servos are not enabled in the firmware and the M42 does not override the firmware configuration.
Is this the case? Any suggestions?
Thanks
Alessandro
