Here are examples of the issue I am facing. The machine will randomly shift the location of the engraving. As you can see on the navy tumbler, the whole engraving shifted up in one spot, and went back to normal after.
The other examples are when it is cutting, it will randomly cut wrong. No there is no hidden lines I am not aware of. The machine just does it. I moved to a new house, so I know something is off after moving the machine(as carefully as I did it), but I have no idea where to start.
I can engrave the same design in the same spot 15 time, and on the 16th time it may do something wacky. Its random when and where it happens. I am not sure if it is a belt issue, or leveling issue, or something even bigger.
Assuming it’s a Ruida controller, delete all the files stored in its flash memory.
If it’s connected with a USB cable, that’s always good for random communication errors. One way to diagnose this is to Send the file to the controller’s flash memory, then run it from the controller without involving LightBurn. Lay down some cardboard, run the same job until it either misbehaves or you’re convinced it won’t.
USB cables are always the last thing:
Using the Ethernet connection eliminates communication problems, with the caveat that you must ensure the router on the LAN cannot assign the controller’s fixed USB address to another device using DHCP. This long discussion gives some background:
