Rev 02 @ 13.2.2021: I fixed faults and little bit modified cable holde iide of the box. Cove remai as were. Box for SKR 1.4 (Pro) logic board Raspberry Pi slim microSD to SD adapter 5VDC step down buck converter for Raspberry 3x step down buck converte for fa. All in one box, cooled by 120 or 80 mm fan. I wanted to put all electronics in to one box and cooled by one quiet fan. I also wanted to have easy access iide the box. In this case is necessary to extend horizontal profile 4040, because part of the box is over the original aluminum profile. WARNING: I have this electronic box on the RIGHT side of the printer (where the power supply is originally placed). For placing on the left side please look at the .STL files that have "left" word in the names. The design is little bit changed. The profile extender is prepared for my printer's tolerances so you may need to use the right tool (really biiig hammer :-)). Electric connection between logic board and Raspberry is made by three internal wires (GPIO14, GPIO15 and GND) connected to proper pi on the SKR board. External USB cable isn't necessary. STEP and F3D files are included for all parts. Rev 01 @ 27.1.2021 I added small box for Step down buck converter which is mentioned below. Connector is JST XH 2 pin. Box is prepared for following hw:
Logic board SKR 1.4/Pro or compatible. Raspberry Pi 3B or compatible (not for Pi 4). 5V Step down buck converter for Raspberry Pi or SD card Female to TF micro SD Male Up to three pcs of Step Down Buck Converte for : or Fan 80x80 or 120x120 (80x80 for "guardless" veion only)
Maybe will be necessary to replace original ribbon cable between board and LCD to the new one - longer.
2pcs PFL10 connector for ribbon cable (cable between logic board and LCD) Ribbon cable, 10 wires AWG28 FBK10H
Screws / nuts: Logic board: 4pcs M3x4 ISO7380, you could use screws from original box. Raspberry: 3pcs M2,5x6 ISO7380/DIN912. Could be used longer. Cover: 6pcs M3x12 (up to 25) DIN912 with or without nuts. Both variants are possible. If you prefer nuts, you have to use longer screws (ca 20 or 25 mm). Box: 4pcs M4x10 DIN912 T-nuts. 5V Step down converter: 2pcs M3x4 ISO7380. You can use for fixation of the MicroSD extender either attached SDclip or heat both pi and "melt" them on the position. Note: For better print quality all screws holes in the Cover (and also above the nuts holes in the main body) are covered by thin layer (0,24mm). For better undetanding please look at Cover in your slicer (level 24 mm). Just use drill or proper screw driver to cut it off.
