This one is blowing my mind. I followed the AjaxCNC / Centroid docs for tool height offsets. I did complete 1 setup on my first part ok- since then I'm just wading into the weeds and crashing trying to do this on the next part! Maybe you can see something I'm not?

Here is the post from the Centroid forum:

I have the following G code: (see below) I just pasted in the first dozen or so lines (as line 11 is the error) I believe it has to do w/ safe, tool change, home heights when tool offsets are entered.

When I go to simulate this 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. line11error_1.jpg
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 tool height offsets- No errors. I just cannot understand what's messing this up?
 
Is your controller capable of conversational programming?
 
Yes. I think I see where you are Going. I cannot import my dxf unless I pay for that ability but could do essentially the same setup and pocket routines to see if it works ok.
 
SOLVED- There is a tiny little box for setting the "tool #" when setting part zero. 1 digit wide. Just so easy to miss on a busy screen! Ahh, we are but the knowledge of our past mistakes!
 
It seems that Centroid wants to peice meal all the canned cycles in their software, and by the time you get all the features that are already there, it adds up to several thousand $ to " unlock" them.
I looked at that program and have a hard time decyphering some of that garbled up code. It would seem to me for a program that simple it would be advantageous to program it from the console.
Another thing....do you have fixture offsets?
 
I remember back in the old days before CNC there was NC. Back then tool height was set by a toolmaker using a arbor holder and height-gage set to the programmer's instructions.
