Tesselation and Arcs

[duisenberg]

When printing a Model having arcs or circles, Mattercontrol cuts them into parts, depending on the models tesselation and prints them using G1 commands.

Though the translation of an arc into lines or steps has to be done somewhere and at least it shouldnt matter so much if its done by slicer or my the firmware, the effect is - depending on radius it leads to a very high number of G commands per mm, even more for a model that comes in "high resolution".

Together with line numbers and checksum, small arcs handled this way lead to a lot of load from communication handling and a stuffed planner, resulting in not well predictable, "uneven" and too slow print speeds - in other words a ruined print output.

Wouldnt it be more applicable to print arcs and circles with G2/G3 commands? This would take a lot of load from the printer and enable to print even smaller circles in a defined speed, so the model would look like coming from a printer and not from a pen.
