Prusa Bear 2.1.0-beta0 released
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.https://github.com/gregsaun/prusa_i3_bear_upgrade/releases/tag/2.1.0-beta...
Z tops design detail
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 the...
Bear 2.1 Z axis
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 fr...

New Z Tops
Here is a view of what the new Z tops will looks like. Both M5 screws are now in front to allow better alignment and improve print quality (reduce warping). Stiffer holding of the Z smooth rod thanks to deeper hole. Several improvement in the geometry to improve stiffness. More precise surface to im...
New Z Motor Mount
Here is a view of what the new motor mount will looks like. Now use M3x10mm screws. Better holding of the Z smooth rod. Stiffer structure achieved by smaller center opening and proper support of the back of the stepper. Avoid bad alignment due to 90° plates that could be over the Z vslot. Easier to...

Need your advice for silver PSU mount
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.Advantages Simpler, no more part to print and ass...

Bear Upgrade 2.1.0-alpha0
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
Future Y stepper mount?
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: 1x M5x12mm 1x M5x16mm 2x t...
Bear Y idler tensioner
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: 3mm of adjustments like on X. Use a single tensioning screw to keep the mount straight and make adjustments easy. The movement use a small rotation but the height of the belt va...

Heated Bed Cable Clips
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.
