This small interface board has taken me a few weeks on and off to get perfected, it performs a few duty's like prime and suck. But in the big picture it will enable you to remover all the
extruder filament detection systems from the CubeX . including Flow detection so you can install any drive system you like.
I have 2 versions. A full on version that the user can make readjustments to on the fly. Or a standard fixed version for just pre tuned to standard setting, for Kisslicer gain set to 1.
For 3D Touch users you can get rid of the 3 mm filament system and go for any extruder direct drive or gearbox of your own design. With out needing to think about converting the hole thing to Marlin open source. the same goes for CubeX users. no need for Arduino
I took a while to fin tune the software, but buy making it user tuning on the bigger board.
