For some reason, I’ve been struggling with my Shapeoko since right around the Christmas rush for my shop. I have been trying to mill some pockets in maple, which I have done hundreds of times before, and am seeing some very strange results where grooves are not being milled straight, and the machine seems to be tailing off when cutting pockets. So far, I’ve squared the machine, checked tension on all belts, adjusted wheels, and thoroughly cleaned all tracks. I have two examples to provide and really hope someone can help!
First, on some of the games I do, I simply mill a 1/8" groove over and over for game pieces to fit in to. I do three boards at at time on my CNC. You’ll notice that on the first board, the grooves are milled at weird angles and not straight, but farther down on the second and third boards, the grooves are fine.
I don’t know what would cause this to not work properly on the first board, but then work fine the rest of the way down? No idea what to look at to try and fix.
The other issue is when I am cutting pockets to store game pieces in the back of a board.
It seems that the bit is not hitting same spot as it goes through the cut cycles, resulting in ridges and totally off center cuts compared to a normal cut.
Pocket not right
Ridges in pocket
Again, not sure what would cause this in just one of the three boards it’s cutting pockets in.
Any help would be tremendously appreciated!!
