I am in the process of converting an old flat bed camera into a PC based mill.
Flat Bed Camera to Mill conversion
The mechanical aspect I feel pretty comfortable with, it's the controller and motor configuration that seems scary. I would like to build this mill as cheaply as possible. I run a small printing company and have been considering doing some engraving or pcb's. I have some motors I would like to use "re-purposed" from an old copier. All three are 5 wire unipolar and 2 of them are identical. I plan to use the matched pair for X and Y (1.8 degree step, 8.8v, 0.8 amps). And, the other (1.8 degree step, 3.36v, 2.9 amps/phase, 2 phase) for Z. I know that the motors used has bearing on the controller. Which brings my questions.
Are these motors suitable? Can the 2 phase be used with the single phase motors? I would like to use them since they were free but, I'm not married to them either.
Could anyone recommend an appropriate inexpensive controller? Should I even consider building a controller? I see kits that seem to hold a lot of promise but, that brings a list of other questions. Does this kit allow for limit/home switches? E-stop? Do I need a driver in addition to this controller? What is a breakout board anyway?
