I don't have a spare $1.2m for the laser
So am I fairly safe to assume that using a cheap Chinese 40w plasma cutter, lightweight trapezoidal screws, bronze nuts and ball bushings fixed to an extruded aluminium frame... I can build a meter square cnc table and get a clean cut through a 3 or 4mm steel plate?
If so, I'm thinking maybe I should go away and build it, then come back here so you can complete my education.
Or does past experience make that sound like a terrrible idea?
