Can we PLEASE get a page on the touchscreen that lets us do the common calibrations without connecting a PC and remembering the magic incantations and magic dance steps?
I’m observing that even similar filaments can have different calibration values! If you want to really get it right, that means re-calibrating on every roll change.
For example, under the extruder calibrate button:
While !Head_At_temp do Heat_Head
Prompt user to mark 100mm above the print module
Extrude 100mm at nominal speed
Prompt user to measure unextruded filament of the 100mm length.
Prompt user for error (- numbers are too much extruded, positive are too little)
Calculate correct setting and apply.
This is somewhat of a pain in the ass to do with a PC, and would be dead easy from the touchscreen.
Some common shapes for X and Y calibration could also be included.
