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.
Any help would be appreciated.
Go to Edit > Device Settings and turn this back off again:
Note the bit where it says “Requires supported firmware” - You likely haven’t installed it.
Thank you. Where would I get the supported firmware?
Thanks for the fast response. Do you plan on a new board the can process faster?
I just updated my 3d printer because of this to 32 bit board. Works great.
I don’t make boards - C3D does that, I just changed the firmware because the speed limit annoyed me. 
If you want to go really fast, I’d suggest a Ruida or other DSP controller, but it won’t work for 3D printing.
Thanks. I will look into them for my k40 laser cutter. They will work faster with graphics?
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.
Thanks. The changes you recommended in the setting fixed the problem I was having. All good now.
