I don't use any temp sensors

Ive done a Denford Triac mod to a CS Labs unit. I can help answer a few questions.

1. The spindle drive needs to be isolated. A new sprint 1220i drive is around £250.
2. The ATC needs that Z is set roughly at Z + 30 from home. This is set for me via my macro for M6 in Mach 3.

You do not need a new sprint card, ignore that advice. You just need to use a v4 or v5 board, they work perfectly

Gents,

Been away for a while, just catching up now. Thanks for all the input been very useful, especially Andy. Think I have enough to be getting on with now, sure I will have more questions down the line.
