Re: Heidenhain Programming

Hi Randolph

M25 - Home Z axiis, turn off coolant and stop spindle ready for a Tool change
M03 - Start spindle clockwise.

The TNC145 I use is fitted to a mill, hence some of the diferences in codes,
but the basics should still be the same.
I'll fire up the beast tomorrow, and check out nesting calls.
I would have thought that 20 - 30 quantities would have been viable on full
blown CNC. I just do model making so the numbers are low, yet CNC makes some
tasks so much easier. ( no axe to grind here ).

As for the teach in mode, I'm afraid I can not help you there - it's not a
function I have.

Regards, Paul.
