Maximum and Default Axes Speeds in MM/Min for MK3
I'm working on creating a profile for the MK3 in a plugin I'm working on, and am searching for some answers about axis speeds. Can someone tell me what the maximum and default (from slic3r prusa edition) axis speeds are for any/all of the following items:
travel speed for X and Y axes (do these differ?)
travel speed for Z axis if it differs from X and Y
travel speed for Z axis for a lift operation, if it differs from normal z travel speed
extruder movement speed for retract
extruder movement speed for detract if it differs from retract
I know there are lots of settings that affect the above, but I just need a good default case, and I'd like to know the theoretical maximum as well, for the profile description.
Also, out of curiosity, do any of the axes speeds change over the duration of the print? I recall hearing someone mention a printer that moved the bed more slowly as the print gets heavier, but maybe this is not true.
Thanks!
