This is the third Grex controller I made for a CNC Plastic Thermal insertion machines for work. The Machine is basically a CNC router with a Beefed up Z axis with a thermal probe mounted instead of a router head. The machine uses heat to insert brass inserts into plastic bosses on parts. The first two I have built have been running 24 X 7 for the last 8 months and work great. We also use it for heat staking and trimming gates with a small router head.
This new controller has a PC built in with hard drive and even a 5 port switch, I have interfaced a DVT inspection camera to the Grex for doing inprocess insert pressence detection. It work great so far.
All the panel cut outs and engraving has been done on my full servo CNC converted X3 Mill.
I have included a link to some pictures, they are pretty big, so be patient!
