Z move before X and Y after tool change

Post by Brian L »

Not sure I understand your issue…. you have the Rapid clearance at 1.25” and your plunge safety clearance at .030”. I usually run .1 on both of those, but no matter. Your part origin is the lower left corner is 0,0, the first hole you are center drilling is at X4.0 Y.5. I don’t see a “random XY move, it’s going where it is supposed to for center drilling the hole, I assume line 170 would be something like G01 Z-.135 F10 or something, then it would rapid back up, move to the next hole and so forth.

All looks pretty standard to me. The post up on my machine moves XY to position first before it moves down in the Z, that way if I’m dragging across the part from the tool change position, I don’t run into a clamp or something. I modified the Mach 3 post to be more specific for my Milltronics, but I don’t think I changed anything related to moving to position first.

I loaded an old job and now every job I've created since has this issue. After a tool change SheetCam inserts a Z move then starts the spindle, then goes to the X,Y coordinate. So it winds up going to a random X,Y on that first move. Sometimes the spindle is barely on before the first cut. I do not have the Parking or Tool Change options set under Job Options.

I'm running version 6.0.1 if that matters.

Here is a code snippet. See the inserted G00 on line 120.

N0130 M07 (Mist coolant on)
N0140 S4500 M03
N0150 X4.0000 Y0.5000

Any suggestions?

Thanks,


Chris
