Hi

Is there a way to get a signal to open and close a valve while extruding/retracting?
I want to use this with a vacuum filler (for paste extrusion) which has an remote input. I already have a lvlshifter (3,3V to 24V), but i cant find a way to get an on/off signal of the duet board.

your are great, ill try that.

i know, i am already using them

i need to use a 5th extern driver ^^

Hi

I would like to remap the driver-pins (en, dir, step) of one of the on-board driver to the expansion header.

I dont need any of the heater or fan pins.

Is this possible without much trouble to change the pins in the Pins_Duet.h?

But it is not possible to just let it run until i stop it, am i right?

Hi there

I am working at a research facility and i am responsible for a food 3d printing project.
Right now we have a running prototype of a "food printing portal" with a duet 0.8.5.

Now we need to experiment with different materials and extruder-speeds. Is it possible to run the extruder continuously and vary speeds with a digital potentiometer in the web interface somehow?
