Step 20 Setting the Platform Position

Step 20: Setting the Platform Position, image 1

Note: With the platform still able to slide left and right, adjust its position so that it lines up to the centre of the printer.
The distance between the edge of the platform and the 3d printed carriage should be approx. 47mm.
Note: When happy it is approximately central, tighten down the remains loose bolts:
- Front platform bolts
- Bracket bolts
