Here's a slightly better video of our VSD-XE powered mill. Cutting acrylic again, this time with a much more appropriate cutter!
Feedrate is 160 ipm, 1/8" single flute cutter, DOC 1/8" at 20,000 rpm.
The pulse smoothing feature in GDTool is giving us really nice smooth curves and a great finish - the edges of the shape in the third photo are quite transparent.
Best regards,
Jason
