I have been using my CNC 3 Axis Router successfully for several years, but now I want to experiment.
I currently run Mach3 with Aspire software and now want to try Laser engraving.
I do not want to build a complete new machine as I have one which is perfectly adequate.
I want to go gently gently and start off by replacing my spindle motor with a 15W 450nm laser head of the type shown.
Question are
  • Is there a freebie software to control my 3 axis system, recommendations please!
  • Will the laser head I have chosen be able to cut 5mm plywood? If not what are my options ?
  • How is focus achieved
  • How is depth of cut achieved

Hopefuly someone can help.

Thanks

George
