Greetings all; Haveing installed a piece of pvc glued to the edge of the disk behind the chuck on the A table that came with this 6040 gantry, I thought I'd see if I could actually make it home itself. First thing I found was that to get no limits, you had to read the docs, and nuke the <MIN_LIMIT and MAX_LIMIT's from the ini file. Then it can turn at a decent rate so I told it to use 360 as the search speed. But that doesn't fly as it not a long enough switch closure (only about 4 degrees closed) to be noticed by LCNC when its all servo-thread. So it sailed right on by and kept on spinning. Had to slow it down and use some very aggressive accels but it finally stops nominally at the center of the closure, then backs away slowly to find the opening of the switch.
But I had not yet added a HOME_FINAL_VEL to the ini file, so it runs wide open to the HOME_OFFSET position, hitting about 21k degrees a minute in the middle of that 90 degree move. I've no idea if its legal, but that final snap to 0.0000 is quite impressive. Half a sec max. Now I need a 7 degree wedge, and I'll be ready to make some very sharp HSS lathe tools. Huge plus if I can find a CBN wheel of about 120 grit that looks like the $20 dremel diamond disk but a lot stiffer. But the CBN folks haven't noticed theres a niche market to fill there, yet. Their fault, my PITA. Thanks all; Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
