Is a Voron StealthBurner with Helical Gears Possible?

9/3/2022

Probably not (or at least without compromises), but I mocked up a model to see if it could work.  The problem is that the entire clockworks needs to move forward by 4mm in order to accommodate the helical gears (which are used in the Mello Libra Mini Extruder).  I think it could possibly work, but it may not really be a clockworks since it could require modification of the cover of the Stealthburner (I believe) in order to have the clearance needed.  It also requires cutting down the latch (by 4mm) due to the re-centering of the tensioner parts 4mm forward.  Even though this is just a mockup, there are numerous things that had to be modified just to get this to point, so I have to question if there will be too many compromises to make it work. I'm gonna bounce this idea around for a while, and I have a thought on how it may be possible to fit in as a drop in clockworks (would require supports to print).  Right now though, this is just an idea.  But it would be cool to get some helical gears in the Voron.  Really though, I should probably just build the printer. 

Update: After playing with the design some more, I think this could work.  I ordered a Libra Mini Extruder (full kit minus the stepper which I already have).  There may be some minor changes to the hardware required but overall I think I can make it fit as a clockwork.  I think I can redesign the latch as well to give it back some of the material I had to remove, may not be pretty but I think it would work.  It's still very much a work in progress design and will be a while before it can be tested of course.

Update 2: Somehow I got all the parts jammed in there and I think it could work.  The entire clockwork and the swing up cover (over the stepper) would need to be re-printed and I still need to verify if the original bolts will work.  Fortunately though it's only the clockwork that needs to be re-printed, and the front part / fan cover should be OK. The front cover will need two 30mm M3 cap screws now instead of the 25mm screws, and there will be a few more M3 inserts needed as well.  I won't be able to test this for some time though since I'm waiting on parts from China still (and that's just to get started building).  If it works out I will post the files on Printables and maybe Github.
