Two things stand out from this thread.First the machine is taking tiny cuts,is it because its a tiny machine with corresponding tiny power?Because the obvious way to speed up the job is to cut a bit deeper.Second the reliance on only the software listed.There should be any amount of software that will import ,dwg or .dxf files however the challenge might be finding something that will have a suitable post processor.Take a look at DXF2CNC for instance.

Is the machine running it's own control or is it Arduino based?
