Taz 2 evolved to 4

Post by 2con » Mon Jun 23, 2014 11:42 am

Can you guys send me in the right direction as to where I can purchase all the parts to upgrade my taz 2 into a taz 4 (mostly heated bed upgrade) as well as a bill of materials (parts to print/STL files to download via links) for the various changes made to the Z-axis hysteria. I want to do it all and make sure i'm not missing anything. I realize i cant upgrade my rambo holster, but that's ok.

Thanks a lot,

The LCD modules are available in the lulzbot store if the 2 didn't have them. I can't rememeber if it did or not. The 24v electronics you are on your own for.

Thank you so much! this saves me a lot of time searching and questioning!

How come lulzbot does not sell a 24V Replacement bed? Where would I go about finding one potentially, or can I just "replace" the power supply to my current bed?

You're welcome!

I dunno why they don't sell those, they probably don't have excess beyond what they need for their own production at this point, but thats a guess.

Another thread suggests CPSX16-5-5 is a suitable replacement for GSASL16-5-5 but was not confirmed. Can you confirm that CPX16-5-5 couplers will work in place of the GSASL16-5-5?


Here are some links to purchase on Misumi for anybody else asking the same question as I am:

Lead Screws: http://us.misumi-ec.com/vona2/detail/11 ... E0-FW7-FY1
Lead Screw Nuts:http://us.misumi-ec.com/vona2/detail/11 ... de=MTSRR12
The GSASL16-5-5 are discontinued on Misumi but here is its brother?

They should work fine. A 16-5-5 coupler is pretty much standard. I've only tried the other ones personally, but they shouldn't be a problem.

Thanks for posting the question and thanks to the folks who replied! Sort of on the same topic, is there a list somewhere of the changes between the various TAZ releases? Just picked up a TAZ3, I've been searching for all the differences but this was really the first post I was able to find that listed some of the specific changes :)

Here's A changelist for TAZ 3 > 4: http://devel.lulzbot.com/TAZ/Guava/prod ... _guava.odt The biggest change from your TAZ 3 to the current 4 is the Z axis drive system.

I'm ordering some cheap sfu1204 ballscrews to try and adapt them to the TAZ3. One question though. Normally ballscrews are fixed at one end with two angular contact bearings. That's a bit overkill in this case, looking at the pictures, are the taz4 leadscrews fixed to the lower bearing at all? Looks like it just goes through a 608zz bearing, so what's keeping it in place axially?
