Bear extruder and X axis (BearExxa) 1.0.0 release

Added 2020-05-24 15:19:20 +0000 UTC

Hi everyone, as you might have already seen the Bear extruder and X axis 1.0.0 have been release! To reduce the long "Bear extruder and X axis" name I have now set a shorter nickname called BearExxa.

Full release note: https://github.com/gregsaun/bear_extruder_and_x_axis/releases/tag/1.0.0

Main page: https://github.com/gregsaun/bear_extruder_and_x_axis/blob/master/README.md

What's new ?

Now compatible with E3D Hemera (BearMera)
Tighter PINDA mount
Self centering of X motor mount
X carriage reinforced
Cable guide back for extruder wires is now compatible with 2.85mm nylon filaments for the cable guide
Documentation has been improved to make things easier and cleaner to navigate and find information
Other smaller improvements
Bear calibration firmware is now in version 3.9.0 (based on latest Prusa firmware 3.9.0)

What's new for Hemera since last Patreon-only release?

The part pinda_mount.stl has been beefed up a little bit, not necessary to update.

Compatibility

Parts that needs to be replaced since release 0.7.0-beta

Here is a list of what you should replace or not from Bear extruder and X axis 0.7.0-beta:

Want to use the E3D Hemera extruder -> replace all parts
Your PINDA mount is getting loose -> replace extruder_body and extruder_cover
Your X carriage has some cracks around square nuts -> replace x_carriage and x_carriage_back
You are using a 2.85mm filament to guide the extruder cables -> replace cable_guide_back_a and cable_guide_back_b
