Prusa i3 MK2S Print Server
Description
**24 Dec 2018 Update:** Modified Camera Mount Including Camera Housing To Accommodated Prusa'S R3 Canted Cooling Fan. This Required A Longer Standoff From The Print Bed Which In Turned Required Stiffeners To Dampen Out Vibrations During High Speed Printing. Also Modified The Way The Camera Housing Mounts To The Standoff. The *Prusa I3 Mk2S* Is A Great Printer Especially For The Hobbyist Or Light Industrial Desktop User. That Having Been Said It Is A Raw Printer Without A Lot Of Accessories That Would Make It A Great Printer. The Is The Forth In A Series Of Accessories That I Designed For The *I3*. The Others Are: - Enclosure Https://Www.Thingiverse.Com/Thing:2396990 - Hepa Filter Https://Www.Thingiverse.Com/Thing:2394452 - Spool Holder Https://Www.Thingiverse.Com/Thing:2398480 The *Prusa I3 Mk2S* Printer'S Primary Input Is Via A Standard Sized Sd Card. The Card Supplied With The Printer Contains A Number Of Utilities And Sample Prints But The Logistics Of Moving Designs To The Printer Is Cumbersome At Best Particularly If The Printer And The Workstation Are Not Close By. Also Provided Is A Standard Usb Printer Port That Can Be Connected To A Print Server. Although Full Size Pc'S Can Be Used To Host A Print Server, There Reliability As A Print Server Is Less Than Desirable Unless They Are Dedicated To That Task. A Better Solution Is To Use A Small But Powerful Computer On A Chip Board Such As The *Raspberry Pi* (*Rpi*). The *Raspberry Pi Zero W* Contains All The Necessary Interface To Provide Wireless Print Serving Along With A Camera Interface Which Supports A Low Cost 1080P Pin Hole Camera. This Design Includes An *Uninterruptible Power Supply* (*Ups*) For The *Rpi*. While This Is Not Absolutely Necessary, It Is Good Practice With *Linux* Based Computers. Much Like *Windows*, *Linux* Can Corrupt Files If Not Properly Shut Down Before Power Is Removed. The Ups Has Enough Capacity To Operate For Several Hours After Power Is Interrupted. This Is Very Useful In Areas Prone To Power Outages That Would Otherwise Destroy Long Print Runs. At Idle The *Octoprint Server* Consumes 0.230 Amps. During The Average Print Run *Octoprint* Draws 0.350 Amps. Peak Consumption (0.450 Amps) Occurs During *Time Lapse Movie* Generation At The End Of The Print Run. An Alternative To Using An On-Board Ups Would Be To Use An External Unit. *Octoprint* (Octoprint.Org) Is A Free *Linux* Based Print Server Designed For The *Raspberry Pi* Computer, Among Other Platforms, And Is Licensed Under The *Affero General Public License*. The Latest Version Can Be Downloaded And Executed On The *Raspberry Pi Zero W* Without Modification. See The Octoprint.Org Site For Details On Downloading And Setup. **Note:** Be Sure To Order The *Raspberry Pi Zero __W__* And Not The *Raspberry Pi Zero*. The "*__W__*" Version Includes A High Speed Wifi Adapter Which Obviates The Need For A Usb Bridge And External Wifi Adapter. **Warning:** This Design Requires The Builder To Have Some Soldering Capabilities And Skills. Please Review The Construction Steps Carefully Before Proceeding.
