Change extruders at certain layer

[slippyr4]

Hi,

I've done a few dual extruder prints with the dual extrusion wizard where I have two STL files for a model specifically designed for dual printing.

However, what I'd like to do - and I'm not sure how - is print a simple STL file and change extruder (for another colour) half way through.

I tried to do this by creating two processes, one for PLA / Right extruder only and one for PLA / Left extruder only. I then used the start print at height / stop printing at height options so that the processes only apply to certain layers. When I "Prepare to print", in the select processes dialog, I Select all and click ok. But then I receive a warning "The selected process is not configured for the number of extruders you have chosen to use"

So i've not proceeded. What should I do? This must be possible but i'm not clear on how.

thanks

Use the "Both" extruders configuration in the easy configuration area and then in the advanced settings set in each process the extruder you want to use in the Layer, Support, Infill tabs.

perfect, thankyou. I'd never noticed the extruder selector on that tab.
