I really liked the rear case designed by Teaching Tech but it didn't quite meet all my needs. The following modifications were made to his case: 1) Added Port to the left side to attach cable chains. 2) Moved electrical components around so it has the capability to hold: a.) 2x DC-DC converter b.) 3x XT60 connector c.) 1x 2-Relay board d.) 1x 30A relay e.) 4x 3-Port WAGO connector f.) 2x 5-Port WAGO connector 3) Reduced the size of the openings for the USB and network port of the Raspberry Pi for a more snug fit 4) Relocated Fans to the lids for better air flow. The intended wiring is to split the 24V coming off the power supply into two inputs into the XT60 connectors. The live end of one of these will be fed into the 30A relay. The relay will then be passed to the power of the SKR/MKS board. The return line from the SKR/MKS board will go directly to the XT60 completing the loop. The second 24V input will connect to the 3port Wago connector next to the DC-DC converters. It will then feed the 2 DC-DC converters. One of these is set to 12V and the other to 5V. The 12V DC-DC converter should run to the 3port WAGO on the the right side and the 5V DC-DC converter should run to the 5port WAGO. This will give you 12V and 5V volt busses. The intent is to run a 12V line through one of the 2-Relays and out to the remaining XT-60 to power lighting. I will try and include a wiring diagram at some point.
