I've spent a whole afternoon yesterday trying to get it work right - offset the 3mm diameter ruby tip at the end of my passive probe from Tormach. I called tormach 3 times but didn't get the problem solved. I was suggested to re-image the whole controller but i'd use that as my last resort.

I did follow the manual and set the tool to #99 in tool table and 2.997mm as the tip diameter. I also did the probe calibre with a bored hole. but the probe will always set the origin to be X-1.5 Y1.5 northwest of the actual part origin, which is the upper left hand corner.

what's more confusing, is when i restarted mach3, without selecting tool #99. the probe worked fine. All a sudden it remembered how big it is and did the 1.5mm offset all by itself, and the tool diameter DRO reads 0.0!

This is driving me crazy, can someone please point out what I've overlooked? Or is it really the controller needs a "re-image" from the DVD (which I don't have!)?

Thanks in adv.
