Dear Patrons,
The final release for Bear 2.1 is imminent and it is time to announce few things :)
New hardware
As announced in my previous post, the official Bear 2.1 kits will come with custom Bear t-nuts and screws !
In case you missed the post, those new t-nuts are stiffer, smaller, have a quality thread, are resistant against corrosion, make the assembly easier and more importantly they do not damage the extrusions!
We h...

This is a bit boring post but important one. I promise to come with something nicer soon :)
Due to new laws passing in several countries and US states, Patreon.com will be required to start charging sales tax on some pledges starting July 1st.
Patreon.com has created a customization tool allowing creators to optimize and so reduce the taxes. We can all thanks them for that, this is a very nice idea we all appreciate.
I took time to optimize the tiers...

I am really happy to share this secret news with you :) . Those are the new t-nuts and screws that will start shipping with 2.1 Bear Upgrade frames.
The biggest problem we faced was to produce custom t-nuts at an acceptable price. We have tested a lots of different manufacturers and several in-house made versions until we could validate those. They are 100% made by LDO Motors.
T-nuts and screws are stainless steel to avoid rusting in humid countries and to bette...
I really want to thank you again, Patrons, for your precious support during the development of BearMera. I really enjoyed doing it and big part was because of you! Thank you! <3
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.

Hi Everyone,
We know that the Bear project is sometimes hard to follow and today we are announcing few things we have made to help with this.
One of the issue is that we share "development in progress" files (the "dev branch"). We think it is important to get feedback during development and to give access to anyone that want to get latest iterations. It also allows you to be part of the development which make the Bear not just our project but a community project....

Little Easter egg game... There are 10 Lego (flat, square, 1x1 and red) on this picture, can you find them?
Happy Easter everyone. Stay home, safe and strong!
For those that are curious about my setup:
As I disassemble a lot this printer and can't carry too much weight (health issue) I am using heavy rails made for servers (with self locking mechanism). When the drawer is extended the printer goes out completely.
Under the printer you have ...

Hi everyone, the BearMera is finally available on my github (dev branch for now).

Enjoy :-)
Hi everyone, sorry for my absence of these last weeks, I have been sick and it is a very slow recovery. I am feeling better but still not 100%. As they don't test everyone in my country, I don't know if this is COVID or not, some symptoms are similar but not all.
I hope you guys are all safe and strong. I wish you can use your Bear unlike me that can't touch it to avoid contamination. I send you positive thoughts to pass through the pandemic as easily as possible.
I hope to publis...

Just want to share some updates on what I did these last days on the BearMera. All those updates will be available soon on my Github.
In the mean time, you can find the new parts in attachment of this post (except the new shroud as I am still working on it).

I did a lot of testing on the shroud. Unfortunately, don't expect a huge improvement on it, once again I could confirm that the shape has only a small...
2020-03-17 11:37:43 +0000 UTC View PostThank you everyone, I am very impressed by all your support! I wish you all the best and hope you are all fine and stay fine! Take care of you and your family. I send you tons of positive vibe! <3
It is really important to stay at home as much as possible to protect you and others. This is the best and easiest way to save life.
A week ago I was in the Swiss mountains (in Valais) for some rest. While it was snowing outside we warmed the chalet with the fireplace. It was the best place to start building a new profile picture! What do you think?

We started March with more than 160 patrons here!!! Thank you, thank you, thank you for your support!!! A dream comes true!
2020-03-03 14:26:19 +0000 UTC View PostI have updated the Bear Hemera zip file to fix homing position of MK2S (gcode file in config folder). I have also added an image of the nozzle and probe offsets.
The zip file is available on the original post "Bear Hemera Files Available" here : https://www.patreon.com/posts/34201760
Thanks to Tom and Orlando for the help on MK2S homing position.

So I have few good and some less good news :D
The good:
Less good news:
Some of you have asked about the Hemera weight and here is a little comparison.
Hemera mount is at 570g and Bear extruder at 585g. The Bear extruder includes the filament sensor so I can say they are very very close.
However, the Hemera has most of the weight lower which might make it more stable compared to the Bear extruder with the stepper on top.
Note that the Bear extruder is using a genuine v6 directly from E3D, not a Prusa version (which has custom heatbreak and non g...

I have published some part of the new Bear X axis in the dev branch. This includes the new X ends and new X carriage, you can find them here:

New Features of X ends and X carriage:
Some news from the dev side for the Bear Hemera! It is going well and I will start printing with it very soon. Once the first prints are done and validated, I will share the files with all Patreons for a "beta test campaign".
The wiring is finally done (was not easy) and supports different type of wire thickness (like LDO nozzle fan, Pinda v1 vs Pinda v2, hotend fan with 2 or 3 wires and so on.).
The heated block is at 135° compared to original position. This helps to make a mo...
More pictures of the Hemera mount for Bear X axis. Here is how the wiring of stepper and Pinda will be routed to the back.
Last picture show some work on the back to let warm air of the heatsink moving up.
Sorry for multi colors print, I am finishing some old filaments :D

Hey, I just pushed the LCD cover on Github and you can download it here:
https://github.com/gregsaun/prusa_i3_bear_upgrade/tree/dev/optional_parts/lcd_cover
I am not announcing it publicly yet, I want to finalize the release RC1 before doing it.
In case of, I made few changes since the version I shared with 10$ Patrons. Not useful to re-print.
A mega huge massive thank you dear Patrons for your support in 2019! Can't imagine how it would have been without your help for the previous decade.
I wish you a success, love, happiness and good health for 2020.
I wish you a Merry Christmas to you, your family and your friends. Enjoy your holidays, eat well and have good talks.
Thank you very much for all your support, it is a precious help. I am very grateful to have you, you're the best!!!

I am working since a moment on a new LCD cover.
You have probably seen my post about the linear rail development. Here are some more details exclusively for you dear Patrons.
Florian designed a special carriage to test different rails configuration you can see on those pictures. We tested two different rails from Igus, 20x60 V-Slot and CPC (similar to Hiwin quality). We also read lots of datasheet from other manufacturers and made some pricing research. We made some calculations on lifespan and implication of belt/wagon positions. B...
Patreons, you are absolutely beautiful! I am working on the best project of my life and it would not be possible without your support, not at all! Thank you <3
