First off I want to thank JJ from seemecnc and Geneb for all the help debugging while I was building this printer kit. Also thanks to all those that walked this path before me for Version one and Orion and helped make the manual easy to follow, full of pictures and extremely thorough.
I'm going to break this post into a few sections to help you jump around since this post is much longer then originally anticipated:
Build Me My Rostock The Journey Begins:
Our hackerspace has an Ultimaker and a PrinterbotJR both of which have been ok but pains to maintain. A friend of mine though converted one of his printers into a Delta and has raved about it ever since. After much research I decided on a Delta printer since we didn't have one of those at the lab and my friend referred me to SeeMeCNC. Now the really hard choices came down to Orion vs Rostock MAX 2 ,aka build your own huge printer

So on to the build pictures :
The build took about 20hrs. I was not in a hurry and took my time enjoying the build. https://www.dropbox.com/sc/72wfgav0x96d ... 7gmtjwOyaa" onclick="window.open(this.href);return false;
I had a few small questions while following the manual here and there but for the most part smooth sailing. My printer parts were much newer then the manual though. Thankfully most of the changes were common sense and the new manual is inbound (i'd love to help if i can).
Arghhh melted my PEEK, failed at my shroud and Improved my second hot end
Melted PEEK: https://www.dropbox.com/sc/d3i7ds722azb ... 0-lCgD-b0a" onclick="window.open(this.href);return false;
So finally got to AutoPid tuning and I got a little bit of smoke and then the PEEK melted off. Tech support was super helpful and I bought some spares and got a spare PEEK. Seemed all the connections were there, the sealant was done well and the wires were solidly connected. I dissected the piece after but to no avail. In any case Kudos to support and Geneb for walking me through how to debug and the help.
Waited a week my replacement parts came in and I improved the hot end design a bit with better cable management extended some wires and added some connectors

So I printed the fan shroud. https://www.dropbox.com/sc/85b6cdgpsrv1 ... pPsJRWWpva" onclick="window.open(this.href);return false; sadly even after some grinding/sanding of the plastic the fan broke. Ordered replacement fans but i don't really need the fan for ABS as far as I can tell. My friend with the delta told me that with PLA I should just use a desk fan so I'll probably go that route.
Pretty Pictures of my orange ABS Pumpkins, the shroud and my first prints.
Now the fun prints with little to no tweaking

That big pumpkin took 38hrs and I still have not maxed out the height the build diameter.
I also finally got OctoPi and camera installed but still have a million questions about proper settings.
Questions Mucho Questions thoughts, ideas and did you make it this far
![Smile :)](./images/smilies/icon_e_smile.gif)
1. Are there any good guides, tutorials or collections of posts on ABS/PLS/T-glase for Repetier and Slicer configurations? Anything that might help me minimize trial and error and get a better understanding of my filaments.
- I have PLA and T-GLASE but i'm afraid of switching over yet since i'm still trying to master ABS. What does the FLOW % setting on the printer actually do? Same for the Speed of print which i've safely brought to 150%. There are also many options for filament flow rates, infill speeds, layer heights etc in slicer and repetier. Anyway links to forum posts or blogs with concatenated info would be awesome. Feeling of being overwhelmed

- slicer settings (lots to read) http://forum.seemecnc.com/viewtopic.php?f=13&t=17" onclick="window.open(this.href);return false; or http://forum.seemecnc.com/viewtopic.php?f=13&t=5413" onclick="window.open(this.href);return false;
2. Nozzle sizes: So I think a .5mm nozzle shipped with my printer. Does decreasing nozzle size just makes for smaller layers and better detail ? What settings change based on that.
3. NOISE: That 38hr pumpkin print drove me insane as the printer is 2ft from my bed and really loud. I heard that it's possible to put these http://3d.grabercars.com/?product=vibra ... 7-astrosyn" onclick="window.open(this.href);return false; Astrosyn dampeners on the NEMA-17 motors? If it is possible how much of a noise reduction do you get and is it worth it?
4. More Noise Help. I'm also considering building some sort of sound dampening case with plexiglass windows. I think this would be ok with ABS as heat is less of an issue then cooling fast but with PLA and these other quickly cooled plastics I would probably need good ventilation in and out of the box? Does anybody have a sound proofing box and if so what material and constraints did you use?
5. ABS failures on Dalek: I actually lowered the print speed on the actual Rostock to 80% https://www.dropbox.com/sc/ewbfv1qxxma3 ... Nz60I1jLoa" onclick="window.open(this.href);return false; .Can somebody help me EXTERMINATE all the filament fuzz that's being extruded? I decided against support structure but might not be able to get away with it. Or I should have printed faster to let it cool. Not sure but I'd love to re-print for my friends kid
6. OctoPi: How do you translate your Repetier ABS/PLA settings to more Cura like settings for the octoPI. https://www.dropbox.com/s/ds39wwnwayrr5 ... 6.png?dl=0" onclick="window.open(this.href);return false; https://www.dropbox.com/s/86pn84lzrlhw2 ... 9.png?dl=0" onclick="window.open(this.href);return false;
7. All Metal extruders. I saw the E3d extruders and the rostock http://micron3dp.myshopify.com/products ... mm-hot-end" onclick="window.open(this.href);return false; all metal hot ends discussed on the forums here. I was wondering if anyone who has these metal hot-ends wanted to comment on advantages/disadvantages they've seen or thought. I would imagine less thermistor shorting and probably better temperature distribution. I'm far away from deciding on this purchase but wanted to hear some thoughts. I'll keep reading on the forums.
8. Dual Extruders: I'm also pretty far from this decision. I'd like to learn my way around the hot ends and the filament
Well I'm sure i'll get many of these answers by digging through the RepRap site and the forums but any help appreciated. I also wanted to share my experiences while building the printer and hope it helps others in the future.
Thanks
