Proma THC with Mach3

[stirling]

No worries Gerry. If you'd bought one of MY THCs I'd have advised you of that before you coughed up your hard-earned

That said Mach3 is dirt cheap for what it does - go on - treat yourself.

OK..bought Mach3 and THC now working...although needs some playing with to get it right!

Quick question...is there an easy way to turn off THC when cutting small circular holes n a piece??...I need to cut a lot of 5mm dia. holes in 3mm steel and it's bobbing up and down and the holes turn out oval:-(

Quick answer... yes. You'll need to get acquainted with your scam post and with mach macros. However it's all been done before in a variety of ways so a quick google will give you more info.
"Small" hole cutting in plasma is quite a topic in its own right so you'll probably want to read up on other things you can do to improve their quality. (A lot depends on your machine's rigidity and accel capabilities and of course just HOW good you need your small holes to be).

Thanks Ian...nothing seems to be easy with CNC...starting to wonder whether it's worth all the effort (and expense) :-0

Ah but doesn't that frosty beer taste so much better when you've grafted for it?
