Servo for an extruder 'stepper'
-
Is it possible to use a servo to drive an extruder (Bondtech BMG, preferably) instead of a stepper with a duet? Anyone have any insight on where to look for a starting point if so?
-
Not that I can offer any help
but just out of curiosity, why a servo? -
Two possible answers, you pick:
For science!
-or-
To compare to a Stepper!

There is no facility in the standard firmware to drive a servo instead of a stepper motor. You could of course use an Arduino or similar to take a set of step/direction/enable signals from the expansion connector and convert them to suitable commands for a continuous-rotation servo.

Thanks for confirming, David.

You could use a Adruino Nano and use the Fan from the Duet.
Write a Sketch for Example aslong as the Fan is "on" turn the Servo I don't know 90° Degrees.
After the Fan is Off turn it back.Should be not to hard to wirte.
