Track of things I’ve added to the Ender 3 V2 to make it work the way I want it to work.

Firmware #

• Upgraded to this firmware.
  • GitHub - Jyers/Marlin: Marlin is an optimized firmware for RepRap 3D printers based on the Arduino platform. | Many commercial 3D printers come with Marlin installed. Check with your vendor if you need source code for your specific machine. this lin
  • Used UBL with BL Touch 10x10

Added Octopi #

• Allow for remote monitor
  • could use Octopi to be the ‘host’ and send instruction, but were gonna use it for remote monitoring
• fixed under voltages with electrical tape - The neverending undervoltage error: octoprint
• decided on klipper and mailsail instead

Upgrade Fan to silent the run #

Working next to the printer is pretty loud when it is running full force

• good video to watch
  • has good links to part list
  • has good 3d parts for fan upgrades
  • used hot glue for wire management

Supplies #

• need one 40x10 for psu
• need two 40x20 for hotend - could be 40x10 if keeping stock fans
• need buck converters to get from 24v to 12v
