Multi color printing

Anyone know how to route the temp from the thermistor to show for all three extruders in the firmware? I've got tool zero showing temp, but the others don't seem to...

Thanks!

For all three extruders? There's only ONE thermistor and ONE thermal sensor in a Diamond head, right?

Yes, there is one thermistor, but I want the 3 "virtual" extruders to all read off tool 0 for temp.

Right now I have:

Tool 0 (extruder 1)
Tool 1 (extruder 2)
Tool 2 (extruder 3)

Only extruder 1 is getting the right temp info...

I think you can't directly configure that, but you can first try editing pin_RUMBA file to share tool0 temp pin for other tools. If that not work, you should go deep into coding about LCD or temp settings. Editing like
Tool 0 (extruder 1) Temp pin:1
Tool 1 (extruder 2) Temp pin:1
Tool 2 (extruder 3) Tmep pin:1

Thanks Fixx - I had gotten that far and it doesn't seem to be working for me - I'll recheck the firmware and get back!

I am almost ready to go with dual E3D-V6 Bowden extruders. Any advice on needed firmware changes welcome

Finally got the dual extruder working. I have a couple tweaks yet to do but here is my first result
