the first cut is the deepest. Today installed my Makita router on my MPCNC, first run was a test for hammer-nuts for my wasteboard, came out even better than i thought. RPM-Controll by external power controll http://www.ebay.de/itm/like/272169773631?lpid=106&chn=ps&ul_noapp=true cheap, but works damn cool, however i do not know if this is good for my spindle… 1st run with 4mm 4cut flathead millbit (cheap china stuff). Also pretty well, even the surface was quite nice. I definitvely love this machine.
