Which it turns out, has been excised from the new users pdf, pointing us at a header file in the source tree, which I of course do not have. Really now? 9 out of 10 of us are running the binaries from the buildbot, so remarks about genius's come to mind. So please, put that data in the ini file DEBUG = 0xnnnnnnnn format back into the users docs so we can at least submit meaninbgfull terminal snapshots when stuff goes aglay. > Thanks Andy. > > Cheers, Gene Heskett After posting this tirade, I went back out and redid the z axis homing so it thinks z=0.000 is about 2mm's from the top of its available travel. This means I have to pre-position it above the switch or it runs the wrong direction looking for it. Is there some way to make that initial search direction automatic? And somewhere in all the restarts to play with that, the program exceeds z limits errors went away. So now I am fine tuning that program I wrote for the toy mill to run with the slightly different offsets that moving the jig from the small machine to the bigger one needs to do its jig locations on. Marching along, adding more global vars so there is only one place to change when something needs changed, the ER20 let go of the mill and dropped it into the jig, digging a slot about an inch deep in perfectly solid white ash. And it was tightened about 1/4 turn from broke when the spindle was started. This hex nut on the adapter has an eccentric internal ridge that may not be properly engaging the groove where the two angles meet on the outside of a collet, and the only reason I can see to explain its existance at all is to engage that groove on the collet to forcibly disengage the collet from the taper when the nut is loosened. If that is the reasoning, I don't think this nut is working as it was designed to. Once today I installed a mill and snugged it up pretty good, only to have the mill display a 1/8" run out at the end of the mill because this eccentric internal ridge apparently didn't drop properly into the groove in the collet, but was wedging it crossways. Should I ask for a better nut, or will this one break in given enough time? You fellows are the ER-8/16/20/32 experts. I never saw one of them in person until about 16:00 yesterday. Anyway I am back to making progress, if I can keep a tool solidly mounted. Thanks everybody. Shuteye time in WV.
