I’ve been running in to an occasional problem with lines showing up on my carvings. I’m still trying to troubleshoot where they could be coming from. Here’s a photo:
(this is a bronze casting from the original wood model carved on my x-carve)
There was actually another line just to the left of the one shown in this photo. Exactly parallel to this one and running the full length of the carving. For orientation, the line runs from top to bottom along the Y axis. But this makes me think it must be something wrong with the X axis for it to cause lines in the same direction like this (but maybe I’m not thinking about it correctly). The frustrating part is that it doesn’t happen often enough that I’ve found a solid trend yet. A few of the things I’ve made mental note of:
- It can happen in any material
- When lines appear, they’re always top to bottom on the carving
- It only happens during finishing pass
- The smaller the bits and the faster the speeds, the more likely it is to happen
Here’s another oddity…Until this carving, I always used “cut x only” in the Meshcam settings. Thinking it was an x axis problem, the carving in the photo above was made using the “cut x then cut y” setting (I figured that second y cut would eliminate any chance of the lines). But as can be seen, the lines still showed up. I’ve searched around for some solutions and the only thing I found was in another forum where somebody said this can be caused by debris getting in the rails or gumming up the axis wheels. I blew them out with an air compressor. Running my first carving since that photo above and waiting to see if it eliminates the problem.
