Notes Before you start:

• There are 5 sections of 2020 T-Slot extrusions. Two will be slightly longer and are aligned with the X Axis which is left to right when viewing the machine from the front. The three shorter pieces align with the Y axis which runs front to back.
• Install the right angle gussets, however, do not tighten them up yet, they will be tightened after installing the Y axis and Gantry.
• The longer horizontal (X) 2020 extrusions overlap the shorter vertical (Y) 2020 extrusions by approximately 29mm
• The shorter vertical (Y) 2020 extrusions do not butt right up to the longer horizontal (X) 2020 extrusions, there is approximately 1.5mm gap
• Do not concern with dimensions and tightening up gusset joints, these will need to be adjusted when installing the Y Axis, Gantry and Waste board.
• Note: The 3 Shorter 2020 extrusions are around 958mm, this added the the 2 x 20mm widths of the longer extrusions is only 998mm, so there will be ~ 2mm gap once assembled. This gap will be set by the length of the Y rails during Y rail installation.
