I installed a Dual Extruder (V2 and V3) so I have the second connector on the tool head mount. If I switch tool heads from the dual extruder to the single extruder without flashing the single firmware first, then I’m stuck. I have an error and the printer won’t talk to anybody so I can’t flash the firmware!
What I need is a dummy plug for the second connector with a 100K resistor across the thermistor pins so the dual firmware will be happy enough to let me flash the single firmware.
I’m guessing that I’d have to buy some minimum quantity of parts in order to make such a beast but I’ll bet the folks at the LulzBot factory could throw some together and sell them on their website for an insane markup but a reasonable price for one.
Alternatively, can someone point me to the pinout for that second connector so I can carefully insert the ends of a 100K resistor?
