Now try to reduce the temperature gradually.

BambuLab PLA Tough suggested temp setting is 190 to 230. So why my Mini tried to print I slowly adjusted the temp. When it reached 235 it the filament finally started to flow.

I had set it to 200 so in a way it was my mistake but it never occurred to me when the range is 190 to 230 that I had to go up to max and even beyond.

Thanks for your help.

When cleaning, use a temperature PETG (240-250 degrees).

When exchanging PETG > PLA, it is necessary to first insert PLA at the PETG temperature and only after all PETG residues have been extruded, insert the PLA again at the PLA temperature.

Would actually have never expected it as almost every filament is having 0.02 or o.o3 accuracy these days.

Cheerio,

I had been printing without any problems using SUNLU PETG. Today I received a roll of BambuLab PLA Tough which I wanted to try. I unloaded the PETG, loaded the PLA, tried to purge (just to be sure) but nothing happened. I increased the tension of my Mini, decreased it but again nothing.

Could a 1,75mm filament be so different that it requires different tension or what could be the reason?
