I know Astroprint is not yet set for dual extrudes but I think there is some bug in the current implementation when dual extruders are set in the printer setup.
I can set the second extruder as active then adjust the temp from the control page but the temp is never reported on the display. I would like to see two sliders one for each nozzle plus ones for fan and bed but if there is only one for a single nozzle then I expect it should display the active nozzle temp.
Edit: I might have been unclear, I can set the temp either from the control panel or on the printer itself…either wait the correct nozzle heats up but astroprint doesn’t indicate the temperature…I suspect it reads a reports only nozzle one…no mater which nozzle is selected on the control page.
