Very careful crafting of text, pictures and construction. Excellent! --Traumflug 05:41, 14 May 2011 (UTC)

The following links were removed because they are not selling the genuine article nor is what they are selling constructed to drawings specified by the developer ,what they are selling is a variant and have not released drawings , if they would like to be re-added as jhead suppliers they either need to be selling the genuine article or making what they sell according to the specifications released for the Jhead. if they would like to sell a variant it needs to be at least renamed and not sold implying it is a Jhead. thejollygrimreaper

Noticed that all useful page content (BOM, replication instructions, etc.) has been slowly deleted and replaced by spam, apparently by the original designer in a fit of jealousy over people being inconsiderate with the design and possibly in violation of the licences. I motion that, since this appears to be a widely-used and necessary component of many printers, we revert it to the version as of 08:03, 2 September 2015, or somewhere thereabout. However, I'm unfamilliar with wiki operations, and the culture around this wiki, so I'm both unsure how to do so or if it would be considered constructive. Matz05 (talk) 16:55, 4 November 2015 (PST)

I have removed the useful information and take full responsibility for it's removal. "Jealousy" is not the work I would use to define my attitude. To me, the best word would be "disgust". I spent considerable time, effort, and money developing a top of the line hot-end, the J-Head. Then, I released a huge amount of information about it's design to the community. MakerFarm duplicated the J-Head Mk IV-B or had it duplicated. They did a nice job with it and I never complained about that. The MakerFarm J-Head Mk IV-B is a true J-Head.

The chinese made a poor, rough, copy and spammed it all over the online markets. People bought the cheap knock-offs and those hot-ends failed. The result was that all J-Head hot-ends got blamed for this failure even though the cheap chinese knock-offs were (and are) very different from the real J-Head hot-end. Most of these people now buy other hot-end designs.

The closest open-source analogy that I can think of is this example: Imagine if somebody took FreeBSD, introduced a couple hundred bugs, then released it as a new Linux distribution. Because of this, people begin to dislike Linux. In my opinion, this is what happened to the J-Head hot-ends. (Please note that this is not meant to say anything negative about FreeBSD, it is just an example.)

The concept of open-source design is to take a product and improve it then release the source code or blueprints. It is not to take a product, break it, then not release any information.
