A little present for you:
https://github.com/gregsaun/BearExxa-V2/releases/tag/2.0.0-beta.6
Trevor Battle@bear_lab I just reprinted and rebuilt my old bear hot end!
The failure points were the PINDA mount and the cable stiffener attachment. I had been surviving on glue and hope for a while.
I'm back to running again, but this would be an upgrade.
@trevorbattle Hey, sorry to hear you hasad an issue there (it's already reinforced compared to stock Prusa). Was this on Bear extruder V1 or V2?
@bear_lab v2 I think, the same as images attached here except with the "big arm" mmu2s filament sensor on top and the front fan is angled...
The aperture for the SuperPINDA kept deforming so it was angling in at the bottom. It worked but kept slipping and losing Z offset. I jammed all sorts of wedges and kapton tape in but eventually bit the bullet and did a reprint.
In the back, the little stub that accepts the long screw from the stiffener just broke off. No big deal but now fixed.
@trevorbattle This is V1. BearExxa V2 has a gearbox, smaller stepper, E3D Revo hotend and a different filament sensor.
Here is the repo of the V2:

The Pinda mount and the cable guide on the back have been reinforced even more on V2. Make sure to not print those too fast as it reduces layer bonding which is important for the cable guide.
For MMU it's entirely different now on V2 and is an official optional part designed by myself.
@bear_lab Much appreciated I'll get shopping.
@trevorbattle Do not hesitate if you have questions!
@bear_lab Am I reading right, that if I wait a bit the stepper will be custom and better?
@trevorbattle I have serious health issues and I had to slow down drastically. It took me 2 years to publish this and while many things are ready for a RC/final release I don't know when I will be able to make it. For sure not in the 4 next months.
