Z height exceeded w/ Tool Height offsets in place.

Post by countryguy »

Sorry to keep posting. I simply am not sure how to figure out what my issue is guys-

I have the following G code: (see below) Just put in the first dozen or so lines (as line 11 is the error) I believe it has to do w/ safe, TC, home distances I setup in dolphinCam. Not sure what the relationship is to Safe,TC,Home's w/ a tool height offset and how the heights are managed?

When I use F8 with tool height offsets & ref tool values below I get an error that "Z axis travel exceeded Line 11"

In DolphinCam I set TC, Safe, and Home values to the same Value. Tried 2", then lowered that to 1.5 and then 1.25. All issue the same Z error.
The Tool height offsets are: ref tool= 1.589 , T6= -2.262 T3=-1.925
Part Zero is 0,0,0 / 4.5 inches of Z travel. , Machine distance to top of part is -2.88" down from 0.0

Man... Sorry to keep posting on this- Maybe this way can help figure out why I'm messing this all up?

I removed the offsets and then I hit F8 - No errors. ?

Try this for illustration:

1) Set up for the job as usual (set Z Reference with reference tool; measure all the tools you plan to use, including, in this example, T6; set Z axis part zero at the surface of the part using any one of the tools, being sure to specify which tool you are using on the Set Part 0/Position screen).
2) Put Tool 6 in the spindle
3) Press F3/MDI
4) Enter the command: G43 H6
5) Verify that "H6" appears in the status window
6) Jog the Z axis down until the Z axis DRO reads +0.1750, and the tool is 0.175" above the part surface.

Can you really jog Tool 6 that low, or do you run out of Z travel first?

Does the DRO display, when it includes H6, accurately reflect the height of Tool 6 above the surface of the workpiece?

Ohhhh Man- I feel like a tool myself now! so so stupid a user error. I simply was overlooking the "Z" tool ID blank on part 0 set. Duh! We're good now. I had set it once - a week ago and simply forget to ever go back to it as it was just not something I was used to inputting. Flew by that screens spot.
