I decided to buy myself an early christmas present and bought an Ender 3. I found that the build process was mainly straight forward but tricky when it came to squaring the x axis against the z axis – I found using the top 2020 extrusion as a guide to get both sides level was helpful.
I think the first three things i will print will be the Z axis motor spacer from here as the alignment out of the box isn’t ideal, the fan guard from here and the filament guide from here.
Here’s some of the videos i used to build and level it.
