I’m experiencing this odd behavior with v0.9.11 of LightBurn when paired with my Ruida controller. For some reason, if I use “User Origin” or “Current Position” when starting a cut, the topmost x-motion cut is skipped. In an example, I tried making this very simple design (10.25-square-weirdnolinetop.lbrn (6.0 KB) which is a quilting pattern cut in 1/8" acrylic.
If I attempt this cut in user origin or current position, the topmost line doesn’t cut. I also tried “send” to the ruida and cut it that way, and the line is also missing. If I switch to absolute coordinates, the line cuts fine.
Thinking this was quite an oddity, I switched to a different design, the “wrenhouse” that was posted on facebook the other day. Low and behold, the same problem was occurring on the top two objects in the cut, but not the bottom object, all four of its sides cut as expected. NOTE: this design’s hole shapes are wrong, if you cut it, the mortises will be too loose. wrenhouse-eigthinchply.lbrn (39.0 KB)
My normal process is to make a shape, select it for cut, and make sure that it is offset from the 0-lines (i.e., upper-left corner would be (1,1) as opposed to (0,0).
I reset the ruida controller hoping that might help but the problem persisted.
I’d love any feedback from the forum on what could possibly be causing this weird issue. Thanks in advance!
