There are 2 o<word> WHILE loops in this program. Each has an o<bypass> test so the whole thing will be skipped while I troubleshoot the other. The machine has beem homed and is sitting at a DRO reading of x0 y0 z0 on entry to the program. Thats near the center of the xy travels, and about an inch down from the top of the post. Inside the IF for each loop, is a G10 L2 P1 X0 Y0 Z0 (to restore the homed co-ords to G54) G92 X0 Y0 Z0 (to make sure its not off a 0.0001) G1 F40 x(center of workpiece) y(offset to put tool at center of THIS circle) Z-8.828 (which is about 5 thou above the top surface of the workpiece as presently mounted) G92 x0 y0 z0 (subsequent motions s/b absolute moves from the present location as it has moved by the line above) Next move is a g1 f10 z-0.025 Error is "move exceeds negative limit on axis 2" The machine is sitting at the homed position nearly 9" up the post and the DRO says everything is at 0,0,0,0. But while I can move it anyplace in its envelope, the code can't lower it 25 thou? ? ? Since it doesn't physicly exceed the negative limit, and I can then run it by hand, downward at least another 1.25" by the time I hit the minimumas set in the ini file for axis 2, I have no other choice but to believe that the interpreter is NOT checking the present position against the value in the machines own G53 map. No clue what its checking with, but the .ini files limits are not being hit. I can put this file, messy as it is because I've now been fighting with this for 2 full days now, on my web page if someone else wants to swing a mad cat, or a 4 foot oak 2x2 at me. Its on the Mill-stf page as 'make_spndle_lock.ngc' at the address in the sig. Thanks. Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
