but well, WMPG on lathe was only working with 3 axes, few days later Centroid made a new version of Acorn 4.80 working with all 4 axes usable on the WMPG. Thats why I feel very good with Centroid, fast and easy problem solving, big respect for this from me.
In this video its quite a senseless use of 4 axis simultaneous, but i think this shows off how cool and easy to use Acorn is.
G2/3 are anyway only circular interpolations of linear moves hard coded in the CNC, but if g-code processing is as fast and smooth like Acorn is, you can do this in g-code also

The manipulation possible of the CNC only with g-code (macros) is in Acorn far ahead over most "big" CNCs like Mitsubishi, Fanuc or Siemens I know from my job.
So long bla bla, here it runs :
