Prusa Mini extruder jam due to wrong PETG temperature?

Being new to 3D printing, I was not sure why my new Prusa MINI+ kept stopping mid-way during a print when using PETG. Turns out that just setting the material to PETG was the issue, as the firmware equates PETG to 230 degrees celcius while the Prusa filament requires 250 degrees.

I'll refrain from commenting on just how stupid it is that the machine and the filament from the same company is not aligned - that should be obvious! However, I WOULD like to know how to change the default temperature of PETG so that I don't have to remember to encode it during slicing or manually tweak during print - which I often forget. Is this possible?

Small side-note; I see other posts/threads about filmanet getting stuck in extruder. This appears to be a natural effect of the PETG being at too low temperature, as it clogs up at the nossle and then the filament gets grinded without having anywhere to move.

Hi,

There is no problem loading Petg filament at 230. I use prusament and it works fine on my mini.

Also, I print some Petg at 210 and I have went down to 235 with prusament with no issues.

250 (+/- 10) is a recommended settings but you can go higher or lower than that. 

Hope this helps.

Which filament profile did you use in slicer? Selecting the Prusament PETG should use their recommended temp settings.
