Print Temp higher than it should be.

[WyoPeeps 0]

I have the UM2+, and have recently put the most current firmware on it. When printing in PLA, the print temp setpoint is 230C, even though the set temp in the material menu is 210C. Can someone give me some insight into what is happening and how to fix it?

There are five temperature settings per material in the printers menu (not only one). The default print temperature is different for each supported nozzle size (besides some exclusions).

It seems you have configured a 0.6mm nozzle in Cura (or in the gcode-header - to be precise).

Thats it! I sliced it to use a .6mm nozzle, but didn't realize that changes the print temp. Why would you want that increase in temp? When printing that hot the PLA just turns kind of sloppy so I have been pulling it back down to about 205C where its printing much cleaner. Is there a way to change that in Cura? I haven't seen anything that deals with temp.

The configured "G-code flavor" controls this behavior in Cura. It's in "Machine Settings".

If you change this setting from "Ultimaker 2" to "Marlin" (the first entry in the list), Cura enables temperature and retraction settings and adds its own start g-code.

The resulting G-code file will "override" the printer settings, you'll have to confirm this explicitly before a print from SD card will start.

 

 

 

For the sake of completeness: the stored temperature setting can be changed on the printer as well - for anyone who likes the "classic" way better.

 

To get an overview about the stored material settings: There should be an export/import function somewhere in the material menu on the printer.
The export function generates a text file on the sd card that can be viewed or edited externally.
