one nozzle dual extruder

[Ky1duck]

not sure if this is the right place but does Marlin support one nozzle dual extruder yet.

thanks

I don't have one.... But "Yes!". I think if I had one, I would put some extra GCode to purge the nozzle (in a safe place) every time I switched colors.

yea but thr problem is I cant find anywhere to tell marlin to use the same heater and temp sensor for both extruders.

@Ky1duck You should use the MarlinKimbra fork of Marlin, which has a SINGLENOZZLE option to do what you want. We have a "mixing extruder" feature pending in our development branch which accomplishes the same thing, but it's not yet merged.

This is a feature I'd love to see too.

Is it as simple as duplicating the pin number for both TEMP_0_PIN/HEATER_0_PIN and TEMP_1_PIN/HEATER_1_PIN? It has compiled and uploaded. And T0/T1 temp readings are duplicated.

[woodsmoke]

Not quite duplicated, and the heaters won't respond. So no it isn't as simple as that.

Thank you for your interest making Marlin better.
You should re-open this topic on MarlinFirmware/MarlinDev for proper followup from the development team. We suggest you to use the MarlinFirmware/Marlin#<topic id> markdown to link back to this original topic.
