I've made some improvements to the extruder feeding mechanism, but unfortunately I cannot use them because it's not possible to set in software the steps/mm.
Can you please allow this setting? It will create many opportunities to the printer as there is an entire open market for extruder improvements. Thanks.
This would need a firmware change just to support a 3rd party extruder setup. Even given the latest developments regarding external material support I would say this is not gonna happen.
Anyway, are you sure you couldn't reach the same adjustment by an extrusion multiplier? If so, this is already possible with Z-Suite: "extruder flow ratio" in advanced settings for external materials.
Letting aside that there are other options of course (*cough*).
Nah, I have no idea. Anyway, are you sure you need the stepper parameters?
I mean, whatever you did to the feeder mechanism should affect the extrusion speed by a certain ratio and I find it hard to believe this couldn’t be compensated with an extrusion multiplier if you just knew this ratio.
And I would think you'd need to calculated that ratio based on the geometric properties of your new mechanism compared to the existing one.
