I've been trying to make a paste extruder and I came across StoneFlower3D. In their site, they mentioned about a feature called Infinite Printing. Please see page number 25 of this document.
They're only using Step
, Dir
, Enable
and GND
from main controller and there's not a serial connection with the controller.
Anyone have idea about how they're doing it?

The extruder is connected to 3d printer mainboard as a stepper driver
. That said it is not using standard stepper motor output, but it is fed directly from CPU digital pins.
Please see OP reference manual.
The extruder has theability to self-feed (load filament) - so that is the reason of kit/printer switches - see pic 1. Then pausing a print to feed the clay tank need to be executed from printer (pause print) and then operated locally in the kit
mode.
