QQ - why Papa Fabio? Is that the alias of the hacker or something?
I had it in mind that you might be able to do this using axis formulas (Function Cfgs). I tried it but it just produced a nonsense toolpath. A bit more diddling and either I'm doing it wrong or formulas don't work properly. Really simple ones seem to work but anything slightly complicated seems to throw it. The example on the formulas dialog implies it CAN handle more complex formulas but not here anyway. (3.43.22).
Ok, now I am really confused. I've been looking at the G-code produced by Simplify3D slicer. I sliced a simple part. At the beginning of each layer to print it positions the nozzle and then there is a line G1 E1 F1800. At the end of the layer there is a line G1 E-1 F1800. What does this code do? Is it the E (extruder) axis that moves 1 mm at F1800, then back 1mm at the end? Or is it a rotary axis that starts by E1 and rotates continuously at F1800, then stops when the E-1 is reached? Any help would be appreciated.
