Octopi Changing to my second extruder on a single color print

[cruzinbill]

Have had this happen twice now and not sure what is causing it. I loaded a print I've done before and it is definitely cut as a single color. After about 2 hours in it just randomly changed to my second extruder and began using it instead.

Anyone know why this is and how to fix it?

Known bug when using Octoprint to control a Rostock over usb with dual extrusion enabled. We're crazy with out move right now, but the short fix is to print from the SD card and shut down the PI. It'll print right every time.

Ah ok thanks, I'll simply disable dual extrusion then enable it when doing that type of print. That makes sense then since it didn't happen until I told octopi there was 2 extruders.

Does anyone know if there's a potential fix for this issue? I love Octopi and my dual extrusion adapter, and would love for them to play nice together!

Afraid not - there's just not enough memory on an 8 bit board to do all the things Repetier is doing.

On a 32 bit board you won't be running Repetier. Running DC42's Reprap on a Duet has no problem doing dual extrusion.
