In Carbide create pro 7 I created a stock size of 50.800mm width (x) and a hight (y) of 25.400mm In the job setup.
When I export the Gcode, Candle and UGS both will see a stock size of x=48 and y=35
Why? is this a bug or am I doing something wrong?
Thanks
Are you machining all the way to all edges?
Stock size isn’t a formal part of a G-code file.
Carbide Create adds a comment:
(STOCK/BLOCK,133.35, 368.30, 22.73,0.00, 0.00, 22.73)
but it’s just a comment.
If the software doesn’t read that, then it’s probably calculating based on tool movement, which would probably remove the diameter of the tool in addition to any uncut material or adding any overcut material.
Yes, I am going to the edge.
What I did with this project is just trim down some stones to about 2mm or so thickness.
They were glued onto a sheet of copper 2" X 1"
Here is a project file where the stock is just about equal to the rectangle I drew within the stock size.
When the project started to cut, the spindle was going outside the 1" (25.4mm) boundary (set by the stock and the drawn rectangle) to the 35mm height. Luckily there were no clamps in the way.
I cut in UGS, but double checked it in candle just to see what the sizes were (same as UGS but different from carbide create.

Your rectangle is 51 x 25.4. The extents of the toolpath are 48 x 22.4
For Candle or UGS to report 48 x 35, your path (including radius of cutter) would have been cutting 51 x 38
here is a snapshot of UGS
it is cutting outside the boundaries set in CC.
the 6mm bit cut 1/2" or so higher up (from zero than it should have)
Can you display the G-code in UGS?
yes, I am on a mac and saved it to .txt… if you cant see it, let me know
Level.txt.zip (1.8 KB)
here is another project I ran with mismatched sizes, this one was all 3D. I didnt get to run the finish tool-path, but the rough came out OK, but still the sizes are off
On that indian chief however, I ran the rough from the offset vectors, not from the outside square where the measurement comes from
A thought I had was the machine type that is chosen. I do not have this machine, just a 3018. Not sure if that would matter but I haven’t tried selecting others and I am not sure what a default choice would be.
Machine selection is an artifact from when it limited working area and calculated feeds and speeds — it’s just a note/reminder now.
UGS visualizer is somewhat deceiving, the indian chief project measures correctly… UGS is measuring from the zero lines out to what it needs to cut, not the entire stock or boundary size. This dont explain however why the first project I mentioned cut out of bounds set by CC
Your G-code doesn’t match what I get if I post the toolpath from the .c2d file

Thanks… So if I understand you correctly, something changed from CC to UGS?
I didn’t do anything to the Gcode (I dont really understand it too well to try and mess around with it), I just saved it from CC then opened it in UGS
Thanks again for looking at this
