I've been lurking for quite awhile and decided I need to have a cnc router. I'd be doing thin plywood, wood signs and general goofing off. Thinking of going with the Hobbycnc stepper/driver board combo and cutting with a Dremel or RotoZip. I'll probably go with the free plans (may make it a bit smaller) and fab it from MDF.
My question is this, will using 1/4-20 allthread be painfully slow. I was thinking of maybe 1/2-10 acme but read somewhere you shouldn't have the screw too much bigger that the stepper shaft.
Also I've got minimal tools for this (I'm an animator and tend to be dangerous around power tools
) Drill press, cordless drills and table saw.
Any suggestions?
Thanks
Dave
