    Exclamation Cannot get the right temperature for petg

    I have a xyz printing da vinci 1.0 and i am trying to use petg. the only way you can change the extruder and bed temps is to re flash the eeprom chip in the filiment cartridge. i am using this coding- (look for the code that is in red text) every time i change the material from flex to pla to abs the temperatures are all wrong for petg. i have tried canceling out the materials part of the code but when i do that the chip remembers what the materials was from the previous re flash. does anyone know of a working program or coding to completely customize all of the temperatures or does anyone know how to change this code to make it work with the correct temps for petg?

    doesn't the slicer let you change temperatures ?

    I knoiw the da vinci is ocked into stupid cartridges that have eeproms. But I also know that you can get round that.

    But even so there should be some other way to adjust the print temps, ieither direct from the control panel or via the slicer.
