7075 is a stronger alloy than 6061, and as such you should scale back speeds and feeds accordingly. Anywhere from 25-50% reduction in depth of cut vs 6061 to keep things happy until you gain more confidence in your cutting recipe.

and @ydrefalk did this:

Did some work in 7075-t6 today. at 2700mm/m 4mm WOC 1mm DOC spindle at 30k. Chipload is about 0.1mm Datron 6mm 4in1 endmill. Pretty happy how it turned out. [image] [image]

but that was on a (rail-modded) Shapeoko so chances are you can push those values with the HDM.
