That means expanding an already too darned big pyvcp panel to make the buttons. And I already have plans to add an overshoot tally in spindle turns at the point of the reversal at the bottom of a peck stroke while rigid tapping. That will use up 1/2" of additional space thats already being overwritten by prompt or error msgs. Its also more coding than the hardware approach. I have that working well on the lathe, but it only has one spindle encoder scale, whereas I have to scale for the backgear in use on the mill where this would also be used. The question is, which is more important information wise. I also need to find an ammeter to put in series with the spindle motor so I can more easily determine when its time to put it in low gear as I'm getting too close to its torque ability in high gear. Needs to have a fs reading of perhaps 20 amps. But that is another "nice to have" item. :) Analog of course, digital's won't catch the peaks. Thanks Andy. I may be back to carving xml code yet. -- Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
