So,
After a month of printing, tuning and poking at the machine, I’m really happy with the K2 Pro Combo so far.
It already feels robust and reliable, and with a few mechanical and firmware refinements it has the potential to become an excellent platform for more advanced stuff – like the lightweight foaming-filament sailplane I originally proposed.

finally start that printed RC glider project, and see how far I can push the K2 Pro with LW-PLA, LW-ASA and HT-LW-PLA in parts that actually go into the sky.
Thanks for reading. If anyone is interested in the bed mapping, the aluminum-tape trick, or the poop chute model, I’m happy to share more details.
