I have tried this car for at least four times and it seems like each time my ex, and Y axis gets messed up. With this most recent carve, I don’t know what happened and why it has created two outlines of the flag as seen in these pictures also, the stripes don’t even line up even though they line up in the simulation picture.
Is it mechanically sound?
I don’t know what that means but it has worked fine for 3 months and whenever I do anything else. It has only been with this cut.
How deep are these slots which you are cutting?
Are you sure the stock isn’t shifting? The clamps are being used in a way which minimizes their leverage.
I don’t think it is shifting…I mean I sat there while it cut and I never saw it move…maybe I need larger clamps
A. Check the setscrews for the drive pulleys on the motors, those are notorious for loosening up after a while.
B. You really need to work on a better clamping strategy. You are using those green clamps incorrectly.
They work best when the hold down screw is closest to the workpiece. In your case, you need longer bolts, and a spacer to so that the clamp is at least parallel to the table.
There are various YouTube videos on different methods to hold down your workpiece.
Look at the clamps for the belts on the gantry. The belts are installed wrong and the belt looks very lose. in the assembly manual look at picture figure 4-5 tiles 1,2 and 3 for the proper assembly method. I believe your belt is slipping and causing your z assembly to track off its mark.

Be sure and check all other belt clamps and correct as needed
