This is a project to convert a CNC engraver to a CNC pcb drill.
It needs
- a little bit of a clean up.
- 3 x stepper motors (NEMA 14 by the looks of it)
- a way of connecting the steppers to the leadscrews.
- a drill of some kind.
- a way to fix the drill to the x/y platform.
- chuck for the drill.
- small drill bits.
- some rewireing to fix endstops etc.
At the moment the engraver comes with an embedded computer (386FX!), which powers up and works fine, and is connected to a control board that has 3 x stepper drivers on it.
Choices
We've got 3 main choices:
- Use the existing controller, but we'd need to give it the steppers and drill that it expects.
- Chuck the existing control board and use an arduino or something to talk to the existing drivers
- Chuck all the electronics and do it all our selves.
The first may be the quickest, but we'd need to get identical parts - the manufacturer may sell them, which might make them more expensive.
The second will involve some hardware reverse enginerring to work out the pinouts to talk the existing drivers
The 3rd might also be fairly easy - presumably we can use the reprap style electronics with it??
