Ok, so I have done some research on these forums and a few other sites as well, and have reached the point where JGRO's design is seeming to be the most appropriate for my needs:

  • The ability to etch and drill through sheet metal.
  • Cut through 1" plastic (preferably derlin)
  • Have a workable area of 18" x 24" x 3"
  • Not cost more than $250 USD


The only questions I have are:

  • What materials would be most appropriate? (I was thinking wood)
  • What motor system, stepper or servo, should be used? (Not looking for speed, just accuracy and cost-effective)


I am thoroughly impressed by the support here and am looking forward to working on this with your help.
