Yes it is. Easier with RRF3. Use E0stop or E1stop as the second z endstop pin.

@matt3o said in Power supply power:

If you have 2A motors even setting them at 1.4A that's over 100W just for the motors

Typical motor drivers act as switching power supplies so multiplying the stepper motor by the supply voltage over estimates the power consumption.

I think that the Duet document that was posted here discusses how to compute the power budget of a stepper motor.

What exactly are you asking?

Do you already have a camera?

I use a RpiZeroW with the Pi cam module running MotionOS as a wifi camera.

@Sindarius Thanks! Something new I've learnt today.

When the printer retracts the filament, does the filament at the location you want to place the sensor go backwards?

If I understand your image, it looks like the filament will not go backwards.

That means that if the sensor measures retraction, it will not properly measure retraction.

I don't know anything about this sensor, so I don't know if it measures both extrusion and retraction.

That's just a text tag from when it was created. You can update that text yourself if you wish.

If you want a truly fresh config for RRF3 you can generate one here:
