Case for Ramps Full Graphics and Raspberry Pi Zero for Octoprint with ATX Power Supply Control
Description
15/01/2018: Added Cover Option Without Frame Holder ----- I Developed This Case To Be Able To Use A Raspberry Pi Zero To Run The Octoprint. My Goal Was Also To Control An Atx Source With The Octoprint. For This, I Used An Npn Transistor (General Purpose) That Is Controlled By The Gpio Of Raspberry. The Transistor Switches On / Off The Ps_On Cable From The Atx Source. Anyone Using Another Type Of Power Source Can Use A Relay Or An Ssr To Turn The Source (S) On/Off. Raspberry Is Powered By The 5Vsb Cable (Usually Blue) From The Atx Source. This Cable Always Has Power, Even If Ps_On Is Off. I Did Not Make A Circuit Board Specific To This Circuit Because It Is Very Simple. The Reset Button Is Connected To The Ramps Reset Button. The E-Stop Button I Solded In The Place Of Ramps Stop Push-Button. As The Buttons Used Are Too Tall I Drew A Small Ring To Complete The Space Between The Top Of The Button And The Case. This Can All Be Changed In The Igs File That I Am Making Available. The Box Design I Adapted From This Case Found In Grabcad: Https://Grabcad.Com/Library/Lcd-Case-For-Ramps-1-4-3D-Printer-1. Thanks Grzegorz Treter For Saving Me Some Time: D Anyone Who Wants More Information About Controlling The Source (Or Using Relays) Can Check This Page: Https://Github.Com/Foosel/Octoprint/Wiki/Controlling-A-Relay-Board-From-Your-Rpi. I Used The "Psu Control" Plugin Of The Octoprint To Make It Work. I'Ve Attached A Plugin Settings Screen. The Design Of The Holder Is Different From The Photo. After Printing I Realized That The Stand Should Be In Front Of The Cable Entry And Not Behind.
