New updates announced today.
The one with the biggest fanfare is the superPINDA, with such a flat temperature response curve that it is more accurate without thermal compensation than the previous one was with thermal compensation. And the mk3s+ gets updated Y bearings, bearing mounts, and rod mounts. Think thetas were also some improvements to extruder cooling airflow design, filament sensor, and whatnot.
Apparently the update kit will be available for $50.
Also announced, a medium texture spring steel sheet, that they believe is a better all around build surface.
