How much did this end up costing you?2con wrote: ↑Mon Jun 23, 2014 11:42 amCan 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,
Doing this years ago would have been cheaper than it is now, but its still doable. Here are the expected cost breakdowns:
If you have a Taz 2, it should be 24v, but you will want to check. If its not 24v, you will need a meanwell 24v 500w PSU - $90, and housing and parts (~$30-90), you will need an all metal hexagon hotend ($~70-ish) or one of the newer ones, you will need a heated bed assembly with PEI ($120) you will need the X end plates ($35 for a set lulzbot.com sells them) the leadscrews ($150 a set new, less if you can find them used, check the lulzbot facebook forum for options, the Taz 6 ones are interchangeable here) the leadscrew nuts ($35 a set) some miscellaneous hardware (the new endstop target bolts and springs, the heat set inserts, a wire harness for the limit switch that is relocated, etc. expect to pay another $50 for all that)
The Rambo board you have is fine, it will take the newer firmware, if the existing power supply is 24 you can keep using that, if you have the rubber mat under glass style heated bed you can just stick a $35 PEI sheet on top of it and use it. CHeck itworks3d.com for some of the parts. They are starting to get rare though. You may find it easier to go to 6 spec if you can find the bed base plate, but that adds $75 in costs for the bed pieces (rubber corners, washers, standoffs, etc.) but removes the need for the X end plates.
I find that a Taz 3 is the ideal conversion piece. I'm currently converting 3 of them to my Taz 5-modified spec. I think I might own most of the used parts out there not currently attached to a Taz.
