Easier to detach supports (PETG) - Cooling it!
I'm thinking about writing a script to post process GCODE to help make supports even easier to remove (specifically for PETG).
Here are my thoughts:
- turn on part cooling fan to 100% when printing bridges (that's easy to do in the Slicer, so that's not a problem)
- turn on part cooling fan to 100% when printing support interface layers
- Lower nozzle temp when printing support interface layers (then reset temp)
- lower nozzle temp when printing bridges (then reset temp)
It's easy enough to identify support interface layers in PrusaSlicer generated gcode. If anyone has done any of this kind of work or some gcode post processing, I'd love help or just pointers.
It's usually easier to design custom supports into the original part file rather than attempt to tweak the generic defaults created by the slicer.
Post process scripts are invoked with a bunch of predefined variables, write a test script to domp them so you know what's available.
Cheerio,

I fully agree, which is why I'm not suggesting touching the automatically generated supports, only altering the cooling or print temperature of the only interface layer.
