I am trying to print an image on my K40 with. Cohesion laser board. When I print it the images get streaks through it, even though the preview show no issues. The streaks are repeatable an occur each time I print images but does not do it when printing text.
Any ideas what I might be doing or do I have a problem with the board.
A Ruida controller will go quite a bit faster than your K40 will. It would be like putting a Ferrari engine in a go kart.
You’ll need external motor drivers as well, so the upgrade will cost close to $400 when you’re done - Though you could find them cheaper used, or get a Ruida 5120, which is a lower level controller with only 2 axis. Ruida is very fast, and very nice.
