I am making plans for my first CNC machine and want to make it desktop size capable of cutting plexi and plastic. I have read a bunch of threads here and am a bit confused on how to determine my drive screw and motor size. Is there some documentation or articles that I can read to get more information?
The plan is to use a rotozip or dremel as my router and I want a cutting bed of about 12" x 12" x 4". I intend to use a 1/4" motion shaft with ball bushing blocks (hopefully the terminology is correct) for support. I really just need to figure out what motors and screw I should target for my first build. Any help is appreciated.
