There are a couple of major flaws with groovemounting (or previous standard HotEnd mounting style):
Fit is highly dependent on quality of part machining
Fit can become loose from repeated removal and refitting
To fight these problems, we're beta-releasing a new, blue, screw-threaded heat sink. Threading also brings some benefits of its own:
It's reliable and repeatable to machine
Wear due to repeated removal and refitting is not an issue
It offers more versatile mounting options, e.g. through a threaded plate
It offers the exact same thermal performance as a standard V6 heatsink and is already in use by companies like Duet3D. We'd like you to try it next, and if you have any feedback then get in contact!
Ships with M12 nut, thermal paste and collet with clip.
