I finished building a small CNC kit (mydiycnc.com) to do PCBs, engrave stompbox enclosures, and to take on another hobby that is way outside my skill set. ;D
Anyway, the machine is built and it works. Now comes learning how to use it. Are there any rules of thumb for material type/job to calculate the feed rate, plunge rate, and spindle speed? My machine is capable of 10IPM with a spindle speed of 5k-14k rpm.
I'm looking to cut pockets in MDF, engrave aluminum, mill PCBs, and possibley make some acrylic jigs (drilled holes and engravings in acrylic sheets). Any suggestions for me?
