I couldn't find a compact 4x GPU online that I liked so I decided to design one. I wanted this thing to be little and compact. This is going to be a 2 part series because I have allot of printing and testing to do. Right now this is for a Micro ATX motherboard but In the future I'm going to extend this out for full size ATX motherboard. Possible 6x GPU Good Entry Level Large Format Printer https://www.amazon.com/gp/product/B07QMPYBD3/ref=as_li_tl?ie=UTF8&tag=fintechcomm0f-20&camp=1789&creative=9325&linkCode=as2&creativeASIN=B07QMPYBD3&linkId=7cbde3724f80d79799e2446ca7b4545d My Favorite PLA+ https://www.amazon.com/gp/product/B081S6BMCD/ref=as_li_tl?ie=UTF8&tag=fintechcomm0f-20&camp=1789&creative=9325&linkCode=as2&creativeASIN=B081S6BMCD&linkId=444a87687c75c3df816b5e3cc212b3f4 Part on Thingiverse https://www.thingiverse.com/thing:4622563 ... https://www.youtube.com/watch?v=smGQu35fJf0

I picked up this Picco nitro engine on offer up for $200. Picco .28 engines are hard to find. This one looks pretty new. The guy said he ran a couple of break in tanks and that was it. I decided to put in some ceramic bearing to give it a little more top end. I don't have me driving on Camera but this thing is insanely powerful. The Ceramic Bearings I used. https://www.amazon.com/gp/product/B004AF8CIS/ref=as_li_tl?ie=UTF8&tag=fintechcomm0f-20&camp=1789&creative=9325&linkCode=as2&creativeASIN=B004AF8CIS&linkId=2cdf7fe8a0693e6cefdfb02e61f9f1cb https://www.amazon.com/gp/product/B004AF8CMO/ref=as_li_tl?ie=UTF8&tag=fintechcomm0f-20&camp=1789&creative=9325&linkCode=as2&creativeASIN=B004AF8CMO&linkId=9d55f52b10a6a93dfffeaa95736644e0 ... https://www.youtube.com/watch?v=g7BQHINkCFU

One of the first things that bothered me about these large printers coming out are the external control boxes. I had the box fall off my desk and rip the heated bed connector off. I want to be able to lift and move my printer as one piece. Its also easier to service the individual components now. Now the power supply and dual mosfet and control boards are separated. I never like having the power supply and board sharing the same cooling fan.

We finally gave up trying to find the oddball CR-10 max LCD. This sonic pad is pretty nice. It was meant a raspberry Pi repalcemt for klipper. I haven't restored one of these yet so I don't know if it has internal flash or cd card. If you have a creailty printer I would go this route. If you have a non creality printer I would go the raspberry pi route. https://amzn.to/3mJsUZh Sponsors http://www.oc3dtech.com http://www.fintechcommunications.com http://www.ocdatacabling.com http://www.ocdatasystems.com http://www.bloodlinefishing.com ... https://www.youtube.com/watch?v=wdVBX194IeM
