Sorry to get back to you so late, but it’s been a busy day catching up with everything that piled up since I’ve been gone.
It’s my guess that your problem probably comes from the fact that in the DXf files the grooves are drawn only to their real lengths. If you are routing with a rounded bit the bit this makes the grooves with rounded ends and so shorter.
To compensate for this you can add extra lengths to the DXF grooves using the “Recess of non through grooves” and “Through grooves over laps” parameters:
the negative value of “recess of non thro…” makes Polyboard draw the stopped grooves on sides longer (a positive value makes it shorter).
The “Through Grooves…” parameter make the grooves that go up to the edge of a panel longer so that the machine goes over the real groove length.
It’s a good idea to give these parameters at least the radius of the router bit.
I hope that I have understood and answered your question.
If not, or if you need more details, please feel free to ask again.
All the best,

We’ve encountered this cutting problem recently and I’m not sure if I need to adjust a setting in the polyboard or Vcarve.
We decided to create a groove on all sides of the back panel in the cabinet. I added a groove of 5mm in the Back’s links and it was projected perfectly in the exploded view. I converted the file to dxf and set it up in Vcarve after. All the panels with the grooves came out in Vcarve’s screen as expected. During the cutting process, the CNC machine didn’t completely execute the groove on the left/right side and bottom panels. Although the top panel was cut from end to end. Is there a setting in VCarve that I need to adjust to allow the CNC to cut the entire groove length?
