FAQ

Isn't the head too heavy?

I assume it weighs comparably or is lighter than BMG-direct heads. With a test printhead made of ABS and Klipper firmware at 1200 mm/s^2, no difference in quality compared to K3D EHP V1 was noticed.

The cooling nozzles are aimed directly at the extruder nozzle!

Yet somehow, CPAP at 60% power can't cool the heat block with the silicone thermal protection removed 🙃

Will it fit H2 and H2 V2s?

Most likely not, but I'm not a hundred percent sure. It's probable that on H2 the airflows could have impact the nozzle temperature.

Some of the air is blowing upwards!

I thought about making an additional element for printing with flex materials to seal the hole. However, the airflow moves in such a way that the blower starts to cool its own electronics. I can't say for sure how much it needs it, but most likely it will be beneficial when placing the printer in an enclosed thermal chamber.

I printed the version for installing BTT SFS and I have a couple of questions...

I made a slight mistake with its placement, and also my SFS for some reason does not correctly detect plastic inside it (probably because I lost the m2 screw from under that weird round thing...), so I'm a bit lazy to adjust it right now 👉👈 (initially, H2 and SFS were supposed to be installed without fittings and the filament was supposed to naturally bend into the feeder coming out of the filament motion sensor)
