Hi all - I’m new to CNC, although dreamt about it for ten years 
I set up my Shapoko 3 XXL and it is working nicely.
I encountered an odd issue while cutting my spoilboard today.
The design has two toolpaths: one for the screws to attach to machine, and the other for the bolts.
The bolt holes get all cut, and then the Y-axis moves up about an inch before the next toolpath starts, so all the indentations are off.
You can see the screenshots with the final cut piece.
Any help shedding light would be super appreciated!

Did you size your design for the specified Y-axis working area (16 or 32 inches), or for the Y-axis working area less the overhang cutting area at the front?

Thank u Will!
The design is 24x32, the board extends back a bit further back, buy the two toolpaths share that same CC design file.
But… I now realize that one set of holes was from an SVG file and the other was added in CC… maybe the issue is there?
Regardless, it should not happen unless there’s a way to use CC to redefine the zero point for each toolpath.
If that’s not it, lost steps most likely.
My money is on @WillAdams’s bet : it is possible that that upper row (x4 holes for screws) is moving the gantry past the mechanical limit on Y, while the first job would not (because the topmost row of holes in the first job is lower…). Did you observe/listen to the machine during the cut, especially while cutting that topmost row in the second job ? Any weird clicking noise ?
If it did crash against on the back plates, then you lost Y steps, and the rest of the job will be shifted in Y.
EDIT: you can check if you can jog manually up to that top row, it should give you the answer.

Ah!! Very possible. Thank you, I’ll create a simpler version and run it to test.
Big help, very appreciated.
update - Tried to cut beyond range hence the 1"(+/-) shift.
