I am currently testing different printing materials to find out the advantages and disadvantages.
While it is relatively easy to use third party materials like PLA or ABS, there are no presets in the firmware for PET-G for example. I can add this to Cura and set necessary settings there, but I can't export them to the printer.
The main problem is that when I want to load "unknown" materials the printer does not allow me to enter custom values for temperature etc.
It seems the UM2 firmware allowed custom material profiles and also importing and exporting for manual editing.
Will this be added later or is there a workaround?
