UPDATE 19-Oct-20: I have updated config files and firmware.bin to the latest version of Marlin bugfix-2.0.x available today. UPDATE 04-Jul-20: I have uploaded compiled Marlin firmware for these upgrades, which was compiled from the latest version of Marlin bugfix-2.0.x as of 04-Jul-20. I have also uploaded the latest configuration files used for this compile. UPDATE: I have added the first draft of the installation guide for this upgrade; it's not quite complete, but I'd appreciate any feedback on what I've put together so far. These are the printed parts I used to upgrade my SUNLU S8 with the SKR V1.4 Turbo board, Micro Swiss direct drive extruder, BLTouch, and 5015 part cooling fan. All parts are original designs except for the fan duct, which was remixed from https://www.thingiverse.com/thing:3781222. The fan mount uses the stock filament runout sensor, hot end heat sink cooling fan, and LED. I replaced the stock 40x40x10 part cooling fan with a 5015 radial fan. To use the PCB mount with the SKR v1.4 Turbo board, you'll need to remove the four existing PCB mounts inside the case. I used a Dremel rotary tool with a cutoff wheel. If you plan to use the USB port, you'll need to widen the opening in the case a little; I used a cheap sheet metal nibbler. In addition to the SKR board, Micro Swiss extruder, BLTouch, and 5015 radial fan, you will also need the following hardware: 1 x RepRapDiscount Full Graphics Smart Controller LCD. The connector for the stock display is not compatible with the SKR board. 3 x M3x6mm socket head screws (fan mount to Micro Swiss plate) 4 x M3x20mm screws (filament run-out sensor and 5015 fan) 2 x M3x8mm screws (fan duct to fan mount) 2 x M3x6mm screws (BLTouch-probably included with the BLTouch) 6 x M3 nuts (filament run-out sensor, 5015 fan, BLTouch) 2 x M4x8mm screws (filament spool holder) 2 x M4 T-nuts for 2020 profile (filament spool holder) 2 x 40cm 20 gauge wire to extend the filament runout sensor cable 1 x retractable badge holder for cable management Zip ties
