Arc Moves + Absolute E
-
Hi DC,
Question 1) Working on my tangential cutter. The gcode includes lots of G2/3 arc moves. However, my slicer(ish) solution works with E in absolute mode (as it's a tangential axis the steps/mm are such that the absolute position of E = the degree its facing to cut 0-359 degrees). As best I can tell my extrusion in arc moves, seem to be in relative mode even with M82. It looks like straight moves G1/G2 do work in absolute mode. Has anyone ever used controlled arc moves with absolute extrusion?
Question 2: For controlled arc moves, can a different axis be used in place of E and have it 'pro-rated' across the distance of the arc like E does? For instance, would G02 X# Y# Z# I# J# F900 U128.366768 move my U axis from wherever it is (in absolute) to 128 spread over the distance of the x/y arc move?
Thanks as always,

Weirdly, I can't reproduce this now. Earlier I had the typical relative code in my config, which I tried to overwrite by running the absolute E code as a macro and it seems that it doesn't take. Once I put it in config.g, it seems to work fine. At least I think that's what happened, anyway, all's well that ends well!
