Purchase Ender 3 at Amazon [Affiliate Link]
While I haven’t used this printer much since I purchased my Prusa MK3S. This printer can still get the job done and it is time to show it some TLC.
The first upgrade I decided to do was the main board.

Tools Required:
- Small flat head screwdriver
- 3mm Allen key
These tools should have been included with your Ender 3
First start by removing the lid to the main board case. pull the bed all the way forward. This will allow easier access to the rear screw on the main board cover, then push the bed to the rear of the machine and remove the two front screws. Lift the lid gently and remove the fan cable.
Then remove the four screws holding the main board to the case.
Next we will pull all the cables forward as possible to give enough slack to change them to the new board.
Pull the cables back through to place the main board back in the case and replace the 4 main board screws
Replace the lid and reconnect the fan cable. Pull the bed forward and replace the rear screw. Push the bed back and replace the two front screws.
Flash new firmware to Ender 3. Selecting firmware from the following URL Download Center: Ender 3. The firmware I selected was “Ender-3 4.2.7 mainboard (32bit)” since the only upgrade I have done was the main board.
Copy the firmware to the root of the Micro SD card. Insert the Micro SD card into the machine. Then turn the machine on. The firmware should automatically be flashed to the machine.
