Mini 2!

Post by reddot » Tue May 15, 2018 8:30 pm

https://www.lulzbot.com/available-soon? ... nnovation# This looks pretty exciting. I'll be happy to learn about the upgrades I can make to my Mini. There's an on-device display. I didn't watch the video closely enough to catch other visible improvements...

Quick run down followed up by the sauce :D

* Aerostruder tool head with new mounting system for easier removal and more stability
* Modular bed system standard
* GLCD with 8gb SD card for tether-less printing
* Belt driven Z axis for faster cycle times and smooth travel moves
* TMC 2130 drivers for quieter than ever operation

Will the mini be upgradable to the mini 2?

We have not made any changes to the sheet metal, so it will be doable! That being said, we have made quite a few improvements that will make it an undertaking to upgrade.

Note, this list may not be complete:
* Replace printed Z uppers and lowers
* Replace printed X end idler and x end motor
* Replace Tool head carriage mount
* New Aerostruder tool head mounting system
-- You can use the existing Aerostruder add on, but you will not get the extra build volume without changing the X motor mount, X idler mount, X motor Carriage, Tool Head Mount
* New Einsy Retro electronics board
-- Some of the connections are different on the board, and the connections are different on the tool head. Re-pinning will be required for some connections.
* Add a z brake board
-- This will require adding wiring harnesses
* Additional belts for Z axis
* GLCD Add on
* Modular Bed System
* High Precision bushings on all smooth rods
-- New printed mounts will be required for the new bushings

There are some other small changes that will not affect performance such as the 2 piece spool holder, so it can be printed on a Mini etc. This should be a good starting point if you are looking to make the upgrade!

Are the Z motors geared?

Nope! The benefit of the Z motors being geared was to prevent a drop of the X axis when the unit was powered off. We added a Z brake board to accomplish the same goal.

I’m in process of printing out parts for upgrading my mini1 to a mini2,just wondering if there are any parts that are reused so I’m not printing more then is needed. Still have the old stock bed for now, will order the new bed later on.

Your Y axis Idler and Y Axis motor mount should be good to reuse, along with the bed corners and wiper mount. Aside from those, you are going to need to re-print all of the Z and X axis components to take advantage of the new build volume.
