I'm very interested in your machine, Ricardo. I implemented a very simple coil winder earlier this summer, with just an X and A axis. I set up the scaling such that the units of A were "turns" (1.0 = 360 degrees). Do you have any more information on your machine available? Photos or videos?

But have to remove all the F words by only at the beginning and change to units/min the feedrate mode, for this. (i asume units dont correlate any more to the actual movement) Seems that my original gcode´s F´s (inverse time) doesnt have a CV continuity or the EMC2 doesnt like that!? I dont have look at the code, but theres a chance that blending isnt working nor implemented, or something else. I think nature of the spatial move come into this If you will run the code for testing, remember to put in AXIS GUI display section GEOMETRY = AXYBC to plot the actual geometry (surely you already know this!) Do you know where to look at the source code? I will look for the hal offset, surely i will find a use for that at time.
