Hi sds2k,

I know this post is a couple of years old now but I just got the monoprice dual extrusion printer myself and am having the same issue. It seems like the firmware on the printer is incompatible with the current version of makerware. I also found some articles that said that I can damage the printer with the wrong dual-extrusion file, so I am hesitant...

Does Makerware still work for you? which version of makerware are you using, and which version of the firmware do you have on your printer?

Thanks much!
