SOLVED Very low temperature needed

[mowijo 0]

Hi there.

 

(Temperatures in celcius)

 

I am experimenting with making my own wax based filament, and for that I need a very low nozzle temperature.

The specifications specify 170 as the lowest the UM2 can go. but I need to go all the way down to 50 degree in nozzle and 30 degree on build place. Is there any way to obtain such low temperatures? I am open to alternate firmware if nessecary.

 

Best,

   Morten

The easiest way is to add a M302 command at the beginning of the gcode file or to your start gcode.

 

If you use Cura: you can switch the GCode Flavor to "Marlin" in the machine settings. This makes the start script available for customizing.

Thanks a lot. I will see how that works once I get some wax-mix extruded.

I will mark this as solved until proven otherwise by me

The PID settings for the nozzle are tuned for around 180C to 240C.  So you might find the temperature is oscillating by 5C or more.  If so I can help you fix that.  Hopefully, you won't have to do anything as the PID system is pretty robust.
