You may wish to reverse the electrolysis cell, and use a different electrolyte, and use a ferritic electrode you don't mind rusting away to nothing. Just saying.
Sorry Keith, not entirely sure I know what you mean.Could you please elaborate?
Or reverse the polarity to start making rust "for whatever reason" you might want rust for.

Ive not looked at the BOM on great deyail but you can get arduino uno clones for £4, stepper drivers £2 each, motors £8 each, laser diode £15 MATCHED laser driver £10, linear bearings and slides £10, limit switches £2 each, PSU £15.Honestly not looked at the BOMor buying these recently, but the main cost will be the Laser diode and driver, go for as powerful as you can get, and get googles to protect from that frequency / wavelength.
