We've purchased the TEP PC interface for the machine, unfortunately it only works through the bundled software TechCAD. This software has severe limitations and also encounters problems importing dxf files from other CAD packages. I've tried some test cuts in 1mm styrene and all appears well until suddenly the machine loses comunication with the PC and it tracks off in a straight line in either the X or Y axis!

Seems a shame as otherwise the machines could be a useful addition to our workshops. Probably it would benefit from a complete new controller and new steppers but then there won't be much of the original machine left!
