Without a long backstory, I modified my TAZ5 to use 1.75mm filament (new hexagon 1.75mm head, .35 nozzle). I had it tuned in really well printing with PLA, at 193 degrees.
I wanted to print some larger items (15+ hour prints) that didn’t need to look pretty, and I thought I could really up the speed by using 3mm filament and a larger nozzle (.5), but the thought of swapping the original head back in (and out agai8n every time I wanted to change filament) sounded terrible so I bought a new extruder, now I can simply swap the 2.
I put the 3mm/.5 in and readjust some settings. I find that my prints are terrible. After much messing about, I turn to temperature. By pushing the temp from 193 to 210 it solves a lot of issues.
So 2 questions:
Should 1.75mm and 3mm filament need different temperatures? I know it takes more energy to melt the 3mm - so a higher initial temp will keep the temp balanced? Am I correct in assuming that?
Second: This 3mm is from a different manufacturer. Should different manufacturer PLA be that different of a temperature requirement?
