Im using replicatorg. When I run gcode a window pops up with a couple values to edit. I input feed rate and travel rate as well as nozzle temp. I always run my PLA at 200C. Then I convert the gcode to xg3. I slap the file on an SD card and print from there. HOWEVER! no matter if I print from SD or from reolicatorg via computer my input nozzle temps get over ridden and goes back up to 230C.
