Greetings all; 2 mistakes in the gcode cost me 2 broken 1/8" mills yesterday. 1st mistake was a G0 x#<_ZUP> which left that line highlighted when I hit esc as it was exiting from cutting the line cord gland hole by cutting the side of the hole until the tool broke.
The hole pattern looked great, in the backplot, 3 holes on the left calculated from the left end, the 4 holes in a square pattern calculated from the center of the panel_len, 3 more holes on the right calculated to the left of the panel_len. But there was a 1 missing from panel_len = 11.875 when it s/b 11.1875. This time I had very carefully stayed away from the offset tweaker, instead I rehomed the axis I needed to move, but g55 and g56 both jumped down nearly 80 thou from the G54 homed position when it reached the code to do the db socket outlines. Z was not moved in the g10 L2 commands used to place the db25 socket outlines. Those commands are G10 L2 P2 X2.576000 Y1.90000000 G10 L2 P3 X9.000000 Y1.90000000 derived from the g54 home=X0.0,Y0.0 positions No z offset commanded but I sure got it. Both X values need a small tweak. So how can I nail the z down so its consistent across g54-55-56? Doesn't rehoming correct all 10 possible co-ord mappings so if no z is specified above, it does not move? Or does it (LCNC) treat rehoming different from the original home. This machine has no home switches so its homed where I click the button, only switches to keep it from unscrewing the ball nuts off the end of the screws, and this pattern uses about 97% of the tables motion X wise. Every spare i/o on parport is used. I need to get a 5i25 into it but have been busy with other stuff, and careing for Dee. I did buy two of these boxes, and if this works well on the g0704, I'll make another just like it for this mill. Thats the plan anyway. But I have got to solve the random Z offsets (its jumped both ways) that I'm not programming into my code. Today later I'm supposed to get a script for my left eye. Since they are transitions lens, hard coated, I might see better a week after I get the script. It takes that long to make them out here in the hills of WV, USA. Would I trade it for some place where I could get them while I wait? Nope, cause I'd have to carry full time too. Nope, not when I can see deer 25% of the time while driving the 3 blocks out of our little cul-de-sac, or they leave their hoof marks in the yard at night 6 feet from the house. I'm an old Iowa Farm kid, would much rather have an 80 acre front yard and another 80 for a back (both with woods) yard than this postage stamp we have, but its paid for! Thanks everybody. -- Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.
