Cuts beautifully though. Decided to try the Precise Bits folk's technique: http://www.precisebits.com/tutorials/ca ... speeds.htm
and coded up a simple file:
Code: Select all
G17 G21 G90 G0 X0 Y0 Z3 G0 X6.35 Y3.175 G1 Z-3.175 F150 (20 percent of feed rate) G1 X38.1 Y12.446 F750 G1 X6.35 Y21.717 F875 G1 X38.1 Y30.988 F1000 G1 X6.35 Y40.259 F1125 G1 X38.1 Y49.53 F1250 G1 X6.35 Y58.8 F1500 G1 X38.1 Y68.07 F1625 G1 X6.35 Y77.345 F1750 G0 Z3 G0 X0 Y0
So it looks like something a bit less than 750 is the hot ticket --- 562.5 or so --- now I just have to edit / update my file to match that.
and... it looks like climb cutting is best.
