T01 S20 M3 The router is a Bosch Colt and doesn't have speed control other than the dial on the side. So the S20 is just so LinuxCNC wouldn't bitch with the M3. And for testing the code on the Mill I didn't really need the spindle going faster than 20RPM. It will do 1RPM if I want. But on MACH3 it just switches on power to the Bosch Colt. This was inches so F5 is 5 IPM. It was about the same speed I'd do with a 0.035" diameter bit using the DREMEL drill press. Speeds up to the original Z in the G81 are fast as are down to the Z. Then G81 switches over to F5 because the original G81 has a G01 in front of it. The 36 holes were drilled in about 1:15. At least according to the original video drilling from the wrong side. It's a pretty kludgy CNC router but it does work.
