Changing extruder temp with xyz advanced

Won't work on the Jr. The RFID chip in the filament sets the temp. Thats why there is a group trying to figure out how to override the chip.

Also please delete your other two post to avoid confusion.

The extruder temperature can be changed in the software.  But, it's not quite as simple as pushing a button.  You need to go to the "Gcode editor" tab in advanced mode.  You'll need to add a line containing M109 XXX  where XXX is the temperature you want in degrees C toward the top of the file.  If I remember correctly (not sure if it changes with different versions) you should see an M109 that's commented out within the first 20 or so lines of gcode.  You should be able to uncomment and change the temperature there.

I know this was tried and proven to work in another thread.  I believe someone used the internal monitor along with a temperature sensor to confirm.

I had the wrong M-code.  Should have been M109 not M104.  109 is extruder temp setpoint.  104 is bed temp setpoint.

In your code, uncomment (i.e. delete the ";") on the M109 line (line # 25 in your listing).  Replace "S0" with "Sxxx" where xxx = temperature in degrees C you want the extruder to run.  For example M109 S220 should have the extruder running at 220degC for the print.

After you make the change to the code, save the .3w file.  I don't have the application in front of me right now.  But, I think there was a "save" button toward the top of the window?

I'm going to guess that delay is the extruder coming up to the new temperature.  I'm still using some old firmware that came originally with my printer.  Maybe the function has changed in later versions.  But, I can't monitor extruder temperature via the LCD screen during a print. 

People who have tested this previously used an external temperature sensor to confirm things really were changing.  If you don't have something like that, I think the next best thing would be to try multiple identical prints while increasing the temperature (and, maybe reducing the temperature?) to see how the print quality changes.  In general, there has to be a value so cold that the filament starts to jam up and not lay down so well.  I'd imagine there's also a point where the extruder is too hot to print well, too.  Like a lot of 3D printing things, you'll have to tweak and play with settings until you get what you want!
