Drill Offsets

[nat_wheatley]

I'm trying to set the X and Y offsets for my 2 drills using the 'TS' command, which then uses the 'S_Center_inHole' file.

When I try to center the rod in the hole in the zero plate, at times there's a delay when the rod contacts the plate, causing the rod to visibly contort. Other times it's fine and the rod stops quickly on contact.

I'm using the same plate I use to zero my bits, and have never had an issue with bits not stopping immediately on contact


Anyone know what might be the issue?

Thanks.

I used steel wool on the 1/4" rod and on the inside of the hole in the zero plate, and everything worked fine. I'm not convinced that that was the issue, but its working, so I'll leave it at that.

Nat:
I'm glad you're up and running... oxidization or something else hindering the flow of electrons was going to be my guess. After 5+ years of flawless Zeroing, I recently had issues that finally came down to the wire connection point on the aluminum plate.

Thanks Steve. I do have a splice in the line for my zero plate, so that was in the back of my mind, but where it has always zero'd fine, I temporarily ruled that out.

I replaced my spindle, which seemed to go fine, then tried to run the TS file, forgetting that the drill outputs are hard coded into the program, and changing them in the file has no effect. I ended up swapping jumpers at the relays to get the file to run correctly.

Nice to have it working, but it was frustrating in that it took more time to set the head offsets than it did to physically replace the spindle. Add to that a bent drill rod, gouged zero plate and cracked dust foot, and I reached some level of frustration. They need to add a note somewhere that indicates that the drill offsets can't be changed for this routine.

Minor rant, but I ended up wasting a fair amount of time chasing this.
