Description

This is a lid to house the switch and harness for my low extruder temp mod for the UP printer.

Instructions

I've used a 13ohm resistor inline with the termperature probe, to trick the printer into thinking the temperature is higher than it actually is. I found 13 ohms drops the extruder temp to around 240 C. ( I found this a good compromise for most colours) Although it still shows 270 in software. The addition of a switch allows quick and easy changes from OEM to aftermarket filament.
The plugs are JST-XT.

Good tip on remembering to switch back. I've done similar and wondered why things weren't printing.....

Nice one Jamie! Ha - you beat me to it! I was going to design one myself. I have had my mod cable-tied precariously to the top for a while.
I'll print one soon! :-)

One little hint with the mod - make sure you have the two wires to the switch and the resistor in parralel. I've found if you accidentally leave the temp on the high setting during a print, you can switch down without it getting the grumbles.
