I have a jam that I have been unable to clear thus far. After talking with Prusa support, we think it may be as simple as replacing the PTFE tubing. I was about to pull the trigger on purchasing from Prusa last night, but ran across some technical issues on the website - maybe for the best since it does cost so much for shipping from Czech. I am in Texas. Browsing the web, I am finding myself confused with getting the same parts that originally came with the MK2. I know it is the V6, but just want a little nudge of exactly what I need and where to buy. I would like to know what options I have for the tubing, the hotend itself, the nozzles and tools that are more reasonable shipping costs. I would like to know my options. I have found the following are authorized E3D resellers. http://www.filastruder.com/ http://www.3dmakerworld.com/store/parts-accessories/hotends/e3d-v6-full-kit http://www.makerfarm.com/index.php/hot-ends/e3d-hot-end-parts.html http://store.makerstoolworks.com/3d-printer-extruders-and-parts-s/111.htm http://www.matterhackers.com/store https://printedsolid.com/collections/accessories-and-upgrades https://www.printitindustries.com/collections/e3d-1 https://www.ultibots.com/e3d/ https://www.smw3d.com/e3d-parts/ I notice a blue wrap? For some reason I am not recalling this when I built my Original Prusa i3 MK2. 12 volt? 24 volt? Bowden? Something else? Just want to make sure I order the correct parts. Also looking for community feedback of if I should avoid any of the above companies or if there is a recommendation for a certain one. Thanks in advance.
Filastruder is my favorite supplier, best customer support of anyone company I have ever dealt with. That said you can get ptfe tube just about anywhere not sure that it makes a difference. I am about 100% sure that the MK2 uses the current cartridge loaded v6 heat block, along with the heat break and heat sink, I just built two of them.
What all are you planning on ordering? If you just want to replace the PTFE tube just becareful if you remove the heatbreak as its easy to bend, also you will need thermal paste for the heat break when reassembling it. Is the fan that blows across the heat sink working properly? If you order from filastruder consider getting v6 nozzles and blue socks, you need to put the blue sock on before completely assemble the carriage as its a pain to get on in post. Considering the V6 come preassembled its not impossible that they forgot thermal paste on the heatbreak, it may not be a bad Idea to reassemble and add more past just to make sure.
Upon a reread of your question, the "blue wrap" is a fan shroud, the MK2 does this in its own way so you don't need it. I am nearly 100% certain that the MK2 is 24V, It does use a very short bowden tube a few mm out of the V6 but not sure if you need the bowden adapter. There is a brass fitting on the top of V6 with a plastic collet, I think that comes by default, I think the bowden adapter is a separate piece, you could ask filastruder to make sure they are quick to respond.
I am sorry - newbie here. I am not following "uses the current cartridge loaded" and only partly understand "heat break". I am a bit aprehensive of disassembling - especially with how delicate some of these parts seem to be. Therefore I am weighing my options between just a fully assembled unit and parts to fix what I have.
Ah sorry its all good we are all noobs at one point E3D release a new version on the V6 block, called cartridge style. It short it makes it easier to assemble correctly. the hot end is made a of a few basic parts, bottom up, Nozzel - the brass part on the bottom the plastic comes out Heatblock - what the nozzle is screwed into and where the heater and thermal resistor go Heatbreak - what the heatblock screwes into and it into goes into the heatsink above it Heatsink - the thing with all the fins Don't be afraid of working on your printer, if you think you might break something get a second heatbreak its not too expensive https://www.filastruder.com/collections/e3d-spare-parts-and-accessories/products/e3d-heat-break-v6 There is a really good wiki on how to assemble it.

Before you start ordering stuff though, make sure the fan is working that blows air on the fined heat sink, you should feel air coming out the other side. If the fan doesn't spin with the hotend heats up you will get a jam. The small fan with the bolts sticking up is the one I am talking about (Photos from Prusa Build Manual)
I can honestly say Elmoret (filastruder) has earned my business repeatedly and for the foreseeable future
