Hi Les - I use it all the time, never had any problems with it and don't understand why it's never been adopted as part of the release. It's a standard feature on any other controller I'm aware of, as is jog in feedhold! My tool changes are always preceded with a move to safe postion. On the router that's usually X0Y0Z50 in work coords. The router has a high speed spindle with ER collets so it's impossible to set the tool length consistently. To counter this all the tool table length and diameter entries have a value of 0. On a tool change I simply replace the tool, click on axis GUI to take focus from the tool change prompt then jog down to the surface, touch off and zero Z, jog up (see PS) to clear clamps and the click on the prompt, axis continues without any problem. I don't use G42 - CAM takes care of the tool diameter. Lathe is similar, I'm using quick change holders as I've yet to get the changer to work with EMC. Same thing, touch off on end of stock, zero Z touch off on side of work and enter work diameter. Jog out on X and Z and continue. PS - The jog away after touch off is unnecessary for me these days, I've altered my post processors to move the tool back to where it stopped before the tool change, on the router it's a two line sequence, Z first then XY, lathe is X then Z :) Steve Blackmore -- ------------------------------------------------------------------------------ WhatsUp Gold - Download Free Network Management Software The most intuitive, comprehensive, and cost-effective network management toolset available today.
