This is for testing Fiberon PETG-ESD filament, specified at 250-290C nozzle temperature.

If using the STL, you will need to modify the gcode to manually set the temperature changes.

The provided gcode is for a Core One Plus, using settings I've been experimenting with based on the manufacturer specs and profiles for other machines.

It's interesting to measure the resistance at each level, using a multimeter -- it decreases with increasing nozzle temp, which matches the specs.

The best temperature seems to be 285-290 C overall, with a 70C build plate. The material is not very strong & the Buddy ABS-ESD filament seems significantly better (but more difficult to feed into the extruder).
