Hey all! Hoping for some help in diagnosing an issue we have, specifically where to actually begin with figuring out how to address this issue. I’ve included a picture to help illustrate the problem that we have. To give some background, after assembling our used x-carve a few months back, we began to notice that is we squared our to-be-carved boards to the front and left rails, the actual carve would be skewed and not square to the sides of the carving material. We started skewing the boards slightly to alleviate how off-square the final carves would be, but eventually I realized that if I took a small 1/16" bit and set a carve up to draw an L-shape on our actual waste board, this would give me a true representation of the y-axis gantry and how parallel it was or wasn’t to the front of the waste board edge, which we had previously been using to judge how to angle our boards for square to the cutter.
So the illustration is a little over-emphasized, but it does illustrate the point that the y-axis is not carving parallel to the front/rear rails. On our actual waste board at home, the left side of the carved y-axis line would be, say, 3 inches from the front rail, whereas the right side of the carved y-axis would be 4 inches from the front rail. The y-axis gantry carves along the x-axis more or less in parallel with the sides of the x-carve, but it’s the left-to-right y-axis carving that doesn’t carve parallel.
Now that I’ve written a novel to flesh out exactly what the problem is, how exactly do I begin with even figuring out where the issues are that are causing this? With those guide lines physically carved into our waste board, it does make it manageable to carve boards and carve them square to our material, but I’d prefer to have things work the way they’re supposed to and not have to resort to temporary fixes like this.
