Hello, quick message to tell you that the release has been published. I am preparing the announcements now ;-)
Z motor mounts and z leadscrew cap have not change since my last post here. However, you need to re-print the Z tops.

On the new Bear Z axis, to have a more reliable X axis ramming into Z tops I have calculated the width of the layer in contact to fit the number of perimeters. Like this I avoid having non reliable surface due to top solid infill.
The bigger surface of contact avoid any torsion of the X ends when they are ramming. It also solves the issue of the screws (used to stop the X ends) marking the plastic over time.

Finally I am ready to share the new Z axis for Bear 2.1. The re-design of the Z tops is now ready. The Z motor mount got some improvements since the last time I shared it with you.
This is only for Bear 2.1frame (same as Bear 2.0 MK3 frame) and it is not yet compatible with Bear 2.0 MK2S or MK2.5S frame. If you have a doubt about your frame you can check this page: 2019-10-23 19:14:53 +0000 UTC View Post

I have just published Bear Upgrade 2.1.0-alpha1, second iteration of the future Bear Upgrade 2.1!
https://github.com/gregsaun/prusa_i3_bear_upgrade/releases/tag/2.1.0-alpha1
Hi everyone, I have just pushed new files today for the future release alpha1. The release has not been created yet, will work on it tomorrow.
What's new:
Dear Patrons,
I am working on the PSU mounts and I thought about moving the silver PSU more on the back and use an M3 t-nuts directly on the v-slot (green arrow on the picture). This would apply to silver PSU only. The PSU will move back by 5-6mm only.
Adv...

Feel free to ask your questions :-)
Dear Patreons, just a quick post to tell you that I pushed the first files for the future Bear 2.1 frame.
This new version includes the new Y axis.
They are on my GitHub, dev branch. Here it is:
https://github.com/gregsaun/prusa_i3_bear_upgrade/tree/dev
This could be the future Y stepper mount. Much more stiffer and the stepper does not touch anymore the extrusion (on MK3). Doing some testing with this one right now. It will still probably need an extra support for the motor, will see what tests are going to say.
Hardware:
I am working on Bear Upgrade 2.1 and it will come with a better Y axis. This picture is a Y idler tensioner.
Some features:
Working on a thank you card to include with all kits. It will be square with a size between 80x80 to 100x100mm.
What do you think guys?
Would you be interested by some posters or t-shirts like this picture here?

New main features
Hi everyone, we are really close to release the new extruder, we are reviewing and adjusting some links and doc. But there is an important point I want to share before.
The new original Prusa extruder has the hotend placed higher up on the X carriage, it creates a 7mm longer Z axis. Unfortunately, th...

Hope to finish this week, meaning release almost there :-) . Yes it is happening :-D
I am much less present online in order to finish this! You can write me in private if you have specific questions.
We have a new guide on how to trim the PTFE tube. Feel free to comment and test it:

For now the tool is only published with the printed parts on the development version. Will be available later on thingiverse for different angles.

I recently made some investigation about the way PTFE must be cut and I am still not very happy with the answer I got, some explanation are missing to me. You can read about it in those tweets :

Here is a PTFE cutter I designed made according to Prusa drawings. The angle on the side that goes into the heatbreak is 60°. ...

I have released 1 month ago a heated bed cable clips design for exclusive Patrons. It is now available for all my patrons.
This is still not shared out of this community. Based on your feedback and interest I will decide to make it public or not.

I had to do something for my heated bed cables that were bending too much in my enclosure. I also switched to AWG14 which makes the original mount too small. Here is an exclusive design for you lovely exclusive patrons that has an angle of 55° and support 8mm sleeve for AWG14 wires.
