Circle and Peg joints

[Gman62912]

I am attempting to build my daughter a blanket chest and I am having problems getting the machine to carve the joint pattern consistent for the full 48". the carving is consistent for about 36" then offsets for the last 12". I have meticulously measured every part of the design and haven't found any discrepancies in the software! I am new to using a CNC machine! Please can anyone help me figure this out?

“Joint pattern”. What joint pattern?

“Inconsistent” and “offset”. How is it inconsistent? How is it offset?

Pictures and a file sample would be helpful to allow us to help you.

Can you post the CRV3D or CRV file? That will eliminate a lot of guessing.

Although I would probably use a profile rather than a pocket toolpath to cut around the outside of the circles, I don't see any particular issues with the file. If it's not cutting as shown in the preview at your machine, then there's a machine issue. Could be losing steps or something is loose. Is it going off-track in the same place each time? You might try contacting Legacy.

CORRECT --- POST PROCESSOR being used to save the g-code for machine???

If it were a post-processor error I wouldn't expect it to pop up towards the end on a very repetitive design like this, but it's worth a check I suppose.

[Gman62912]

I ran the code three times and it did the same thing on all three!

Your material is actually a bit smaller than your design so your pins are getting a small flat area (on the top and bottom pins). If your board is not exactly parallel to your X axis on the CNC machine that might exaggerate this issue on one side or the other.

I see No Problems with the File either.
