Install the remaining fixed guides to the gantry.
M4 x 30mm bolt
M4 nyloc nut
Tighten the fixed guides firmly.
Adjust the Eccentric Guides to get a tight grip on the pillar rails, you should still be able to move the gantry up and down by turning the lead screw. Once happy tighten the eccentric guides firmly.
You may have an eccentric guide left instead of a fixed one, this is OK, just use one of the eccentric guides here instead of fixed. Just make sure that when your adjusting it that the gantry arm is kept as straight and parallel to the platform as possible.
Make sure that you install the eccentric guide on this spot, else the tool carriage will bump it and not reach the endstop.
