I've got an epilog Legend 32, 30 watt. Until recently, it worked fine. I've been making event plaques with it, no problem. Just now, it started not following my vector lines properly. And repeatably, too. It consistently makes the same errors in the same spots.
I tried cleaning and lubricating the bearing surfaces. I tried placing the workpiece at a different spot on the table. Same problem.
This is how this image is supposed to look:

And this is what it is doing now:

Note the E, S, and bottom left corner of the image show the problem most noticeably. Same spots, same error.
The only other thing I would think it might be is dirty encoder strips, but I've never been able to find any on my machine. The Epilog website says it is equipped with them, https://www.epiloglaser.com/laser-ma...-techspecs.htm but the manual makes no mention of them and I can't find any encoder strip to clean anywhere on the machine.
I'm really lost at this point. If anyone has an idea of what could be causing this problem, I'd be eternally grateful to hear it. Thanks in advance
