im trying to cut holes in stainless steel and need to figure out how to manage the heat to stop it from warping. piercing the material first then ablating it away in circles is probably better than slowing going to the center heating everything up until it melts away.
Interesting… using my Grbl diode the offset fill operates as shown (inside to outside) however using the fibre galvo it reverses the procedure as you are experiencing.
I do not know of a way to invert this.
There may well be a reason behind this, that others know.
