Not Able to Configure a 2-to-1 Mix/Switch Extruder
I have been successfully using Repitier FW in a dual extruder configuration with two nozzles/heaters and steppers. I replaced the separate nozzles/heaters with a 2-to-1 heater/nozzle and cannot get a configuration that does not result in an error with used on the printer.
I have tried about every combination of the mixing/sharing selection available and even tried to manually disable the second heater and use the extruder 0 sensor. Every combination I have tried has resulted in what must be undefined extruders and a repeating error buzzer. The extruders show up as def in the display.
I have been using the Dev version of the FW, but I've tried both .929 and Dev and get the same results. At one point it looked like a mirrored stepper would be the answer, but that results in a compiler error, flagging something that is undefined in the .H config files.
Comments
In the configurator there's no way to not set the second heater and termistor pin to -1, please fix it with something more understandable.
The "single nozzle" or "shared heater" option is missing, which should disable the whole section of the second heater.
I use the 1.04 DEV.
Extruders share same heater from extruder 0 definition (SHARED_EXTRUDER_HEATER)
and -1 is same as "Disabled/no pin assigned" which you can set already. For sensor use same pin/type as for extruder 1.
