https://youtu.be/iwWsHzd8Bbw Note - The LCD Screen and Knob are re-works of the Prusa LCD mount which is open source. Thanks to Prusa for this open-source design. Now added a filament sensor mount, get it from https://www.thingiverse.com/thing:3526524. Here are some upgrades I've made to my CR-10S 3D Printer. I bought a damaged one with a blown motherboard so decided to upgrade rather than just replace the entire printer. My shopping list includes: MKS Gen L 1.0 Motherboard 2 x TMC2130 Drivers 24v heating element 24v CR10 Pro Heated bed Magnetic Bed 5v Noctua 40x10 Fan I'm running Marlin 1.1.9 with mesh bed leveling enabled as the heated bed I received was far from flat. The printer is now a standalone version as I hated having the control box separate. I designed a motherboard / mosfet case and also a new PSU case that accepts the original socket and switch. I needed to do some soldering on the heated bed as I wanted to keep the original connector, but it wasn't necessary. However, it was just the route I took. I also needed to connect both Z motors onto the same connector, so more soldering was required. I've made lots of little tweaks in the firmware as I'm running the original 12v cooling fans for the extruder connected to D7 (extruder 1 output) and I've throttled the pwm output on the cooling fan to 70. Then I connected the motherboard housing fan to pin 5 (servo), which then turns it on and off with the stepper drivers. The best thing about all this is when it's not printing, it's silent - not a single fan is running at all. If you want to download the firmware I'm currently using to have a look at, you can get it from http://diyrc.co.uk/images/CR-10_MKS_Firmware.zip.
