Hi all,

I apologize for asking what is probably a basic question. What are the steps and parts for upgrading to Taz 4?

In particular I am looking for info along the lines of, “too many things have changed, you can’t upgrade earlier models to it” - or, here are the things that have changed (or are the same). And by this I mean, here are links to the Aleph parts store for things you don’t have, here are links to the particular printed parts that have changed.

I have been searching this forum (although “upgrade” can’t be used as a search, so this is tough), using various terms in Google, and examining the Aleph website and source files, but haven’t found the info yet. I happen to have a Taz 1, though any specific info on upgrades to v4 would be useful. What I have found so far about changes between Taz versions seems to be:

- Taz 2.\*: LCD (easy upgrade with parts on sale, instructions here: [http://ohai-kit.alephobjects.com/project/8e9dc2a9-2373-400e-9efc-bc7e24ded7fb/](http://ohai-kit.alephobjects.com/project/8e9dc2a9-2373-400e-9efc-bc7e24ded7fb/))
- Taz 3.\*: 24v/bed (doable upgrade with parts on sale, instructions here: [http://ohai-kit.alephobjects.com/project/taz\_12v\_to\_24v/](http://ohai-kit.alephobjects.com/project/taz_12v_to_24v/))
- Taz 4.\*: Y-axis mounts? drive rod system? power supply?

…is this right so far?
