According to my material selection guide, polyester CTE is 4 E-5 /F, cast iron is 6 E-6 /F. Most unreinforced plastics as quite similar in expansion to polyester. The difference in expansion works

Actually, the DanCAD pinout has provisions for limit switches (All axis's + & - are ganged together to one input) and for home switches on all 3 axis's along with 3 (if I remember correctly) relays.

I haven't heard much discussion about sources for servos. What are people using out there? I remember a Circuit Cellar column in the early days of Byte wherein Steve Ciarcia described a neat hack for

Yes, I second that, strongly! I built up a little circuit that connects up to the fault relays of the servo amps, and the fault input to and servo enable from the CNC, and also a manual e-stop

Tim, make an adapter with a male and female DB-25 plug. Sort of a pass through connector that crosses signals to fit what you need. I have made a few to adapt controllers that were using Dancam

Remember that if your machine has other than 64MB of RAM you'll need to change the 0x3F00000 to match your system: 0x0F00000 for 16MB systems 0x1F00000 for 32MB systems 0x2F00000 for 48MB
