Found some screwups by putting in a better bunch of debug's, and got it to where the backplot looks good. But someplace in the hal file fixins I seem to have lost the lowpass.0.out effect on the spindle enable, so now its busy ripping cross bars off the pulley and belt on the spindle startup. Sounds like its stripped every gear in the head, but its the belt hopping the pulley. Nasty rattly buzz. So I shut it down as it may be days before I get back to it again, they are going to put some nerve blocks in my back tomorrow, and I've been advised to have a driver along. No clue how I'll feel after that. I have got to figure out how to put some jackscrews into the countershaft mount, I have those bolts not more than 1/8th turn from broke now. And figure out where the lowpass got lost, I just # signed the lowpass.0.out in the hal file which should have disabled the motor, but didn't do a thing. I am about to start another reward fund for that Murphy guy. ;-) Cheers, Gene -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
