Open Source in 3D Printing - Copycats, GPL Violations, and China
Video Channel: Design Prototype Test
Open source in 3D printing is a contentious issue. In this video we cover the history of why the open source movement was created, and then we talk about how this relates to the consumer of 3D printer open source products. tl;dw Innovation is good, Knockoffs are bad. Don't buy clones/knockoffs.
Addendum to the video: I’m not innocent. I have purchased cloned products in the past, If you watch my early videos I even talked about my cloned products in a positive light, but that was before I gave it any serious consideration. I just thought I was being a smart shopper. I realized my error, and I’m not supporting copycats anymore. You shouldn’t either. Nobody wants to be the sucker paying too much money for a product. Everyone sees it as being in their self interest to buy clones, yet the fewer people who buy the expensive genuine versions of the products the slower the innovations will be released until they will stop coming altogether. That goes against everyone’s self interests. In effect, if you proudly support copycats, you are not yourself a thief, but you are definitely leeching off the good will and stand up behavior of those who supported original creators.
Marlin Firmware - AMA: http://clipreview.net/qnRg-hivUwE
A YouTube user named Chilternflyer gave me a list of innovations he thought Prusa was responsible for. Here I addressed each of the items in his list:
-Laser filament sensor: Not Developed by Prusa First seen in a post by a DIYer who modified a mouse sensor to accomplish this task: http://hackaday.com/2016/12/08/this-...
-Mesh bed leveling: First seen implemented in Marlin firmware not developed by Prusa. http://plus.google.com/1138259895568...
-Trimanic drivers with SPI implementation?: Are you kidding me? You put the name of the company right there in the bullet point! Trinamic (not Prusa) is responsible for this innovation.
-24V electronics: Many DIYers were converting to 24v long before Prusa. There are many posts on social media showing these hacks. He definitely is not responsible for this innovation.
-Pinda probe with internal thermistor: I personally discussed this in a video six months before Prusa released this feature on the Mk.3: http://clipreview.net/_-fAMAnn3_s?t=17m43s and then I made a video calling Prusa out on this fact and he personally responded to my video showing me a design published on reprap's website from 2015 for a temperature sensor on an inductive probe. This is a very old idea which Prusa himself admitted he did not develop.
-GENUINE E3D all metal hot end: Again, are you kidding me? You put the name of the company right there in the bullet point!. E3D (not Prusa) is responsible for this innovation.
-Bondtech gears: Again, are you kidding me? You put the name of the company right there in the bullet point!. Bondtech (not Prusa) is responsible for this innovation.
-Crash detection and recovery: This is a technology called "stallguard"developed by Trinamic not Prusa
-Power fail recovery: Not Prusa's innovation. Here is a Reddit post from way back in 2014 discussing the topic: http://www.reddit.com/r/3Dprinting/c...
-Noctua fan: Again, are you kidding me? You put the name of the company in the list. Noctua (not Prusa) is responsible for this innovation.
-Belt Tension measurement: This is based on the Stallguard technology invented by Trinamic. Prusa is not responsible for this innovation, and it's usefullness is debatable.
