I haven't check to see if ppdev can be nuked. ATM on my machine, all 4 modules are loaded and emc-2.6.0-pre is running fine. > > So maybe the hal is the problem.

It seems the ink on the 'in' is about worn off the paper here too.

No clue why, but it seems stepconf has always done it, so I haven't played with it. Perhaps, given that there could be after market parport cards whose address may be above the usual 0-65535 address range and therefore needing an extra byte for a 24 bit address to access them, that the room for that 24 address is reserved. One could theoretically test that by using "0x000378", which would be the same thing but supplied in 24 bit format. I'd bet a bottle of my nearly beer it would work, and if I lose the bet, you have to come to North Central WV to collect. :) > setp parport.0.reset-time 5000 Check your drivers for required minimum step pulse width, you may be able to reduce that, which means the base thread might also be reduced by the same amount. Again, not something I've played with extensively but when I was using a xylotex driver, 2000 seemed to be a great plenty. But I doubt that is whats being the showstopper now. > addf parport.0.read base-thread > addf parport.0.write base-thread > addf parport.0.reset base-thread > > net spindle-cw <= motion.spindle-forward > net coolant-mist <= iocontrol.0.coolant-mist > > setp parport.0.pin-01-out-invert 1 > net spindle-cw => parport.0.pin-01-out > net xdir => parport.0.pin-02-out > net xstep => parport.0.pin-03-out > setp parport.0.pin-03-out-reset 1 > net ydir => parport.0.pin-04-out > net ystep => parport.0.pin-05-out > setp parport.0.pin-05-out-reset 1 > setp parport.0.pin-06-out-invert 1 > net zdir => parport.0.pin-06-out > net zstep => parport.0.pin-07-out > setp parport.0.pin-07-out-reset 1 > setp parport.0.pin-14-out-invert 1 > net coolant-mist => parport.0.pin-14-out > > #net estop-ext <= parport.0.pin-10-in-not > net estop-ext <= parport.0.pin-10-in > net min-home-x <= parport.0.pin-11-in-not > net max-home-y <= parport.0.pin-12-in-not > net max-home-z <= parport.0.pin-13-in-not > > setp stepgen.0.position-scale [AXIS_0]SCALE > setp stepgen.0.steplen 1 > setp stepgen.0.stepspace 0 > setp stepgen.0.dirhold 35000 > setp stepgen.0.dirsetup 35000 35 u-secs?

But the machine has been rebooted 3 or 4 times, and lp is now showing up in the lsmod output again, AND emc (2.6.0-pre) is still running nicely right now, and I am about to carve a pocket for a fixed sized small piece of pcb in the top of a 4" x 6" x 1/2" piece of HDPE. However in this case I am going to put a hole pattern in the corners of the pcb into the HDPE before I mill the pocket since from experience, the HDPE will swell around the hole slightly when I run the tap into it for a 4-40 bolt, so I'll let it swell, and mill the swelling off as I mill the pocket. Sometimes you have to outsmart this stuff, it works for Murphy you know. :) One final comment, what mode is the port set for in the bios? ISTR mine is set for SPP ATM.
