In the wake of two days of failed prints, an update on the Taz:

PLA & The Budaschnozzle:

Do not let the Budaschnozzle idle at temperature unnecessarily
Make sure the extruder and the hot end are perfectly alligned
- Slide filament through both holes as you bolt them in. The filament should move without much resistance.
Install a fan pointed at the heatsinks but blocked from the heater block

I learned those things the hard way yesterday.

Bed adhesion
On my first print a glass bed at 70C was used with no problems. My second print would not stick until I used an elmers glue slurry. 4 Parts water to 1 part glue painted on when the bed is warm.

The last week was basically spent rethinking our decision on 1/3 to use 3 smaller barrels and designing a way to use 2 55gal barrels. This required cutting of the old saddle and building/mounting a new, much larger, heavier one. I have my doubts but am otimistic. I want to see some testing with the 1000lb payload on there. Gabi is almost finished the waterwheel lift mechanism. There is no video update because of technical difficulties.

Here is a video of my first print on my Taz!

Nice coverage in The New Yorker.

Completed my first print. Video is rendering at home. I will upload it another day. For now I have a video of stopping a leak in the Budaschnozzle.

We decided to use two 55gal drums. I cut off the saddle and will begin workign on the new one on Friday.
We are making three 25" wheels from laser cut 11ga mild steel. Here are the files we sent to the machine shop:

A fun way to navigate this wiki is to use the random page tool. You can put this link: http://opensourceecology.org/wiki/Special:Random in your bookmarks toolbar if you are in mozilla.
This is from the other day:

I started to look at the budaschnozzle. It needs to be cleaned. I started that process but ran out of time. I will document it with a video when I finish.

We decided to add 3 15 gallon barrels to the sides of the 55 gal barrel to give a total capacity of 100gal. We also lengthened our shelves. I'm ready for a day off, which is coming.

So Christmas happened and then other stuff and it's now apparently 2014 and I haven't finished the Taz or the Water Wheel...

Ordered a part for the nozzle and then it should be 100% operational after a cleaning. Haven't had any time at all to work on it other than to build a more permanent space for it in my room.
The water wheel is coming along. I will post some videos from youtube below. It is now day 9 but they haven't really been full work days. Nothing like a production run at FeF as we are using rusty material which is not square and we don't have a complete design going in to it. It does look pretty good, though.

Finished

Main Frame
Wheels
Barrel Mount
Seat arms
Seats

To Do:

Water Wheel Welds
Lots of Grinding
Plumbing
Water Wheel Axle
Water Wheel Lift Mechanism

We are also considering adding another barrel for 2x water capacity.
