This is a critical part of the assembly, at the end of this the gantry assembly should be vertical
to the bed on the base assembly and in line with it horizontally. It’s worth taking the extra few
minutes to get this right!
A. Put the base assembly on its feet bed on a flat surface. B. Slide the gantry over the sides
of the Base assembly (It’s a tight fit). C. Adjust the gantry position so the holes in the gantry
uprights are over the threaded holes in the slider nuts on each side of the base. D. Place the
Gantry Alignment Tool under one of the gantries. E. Press the gantry down so it is evenly
touching the top of the Alignment tool, the holes should still be aligned over the nuts.
F. Insert the nuts and finger tighten. (Repeat for the other side.)
Place the long edge of the Gantry Alignment Tool into the slots between the gantry upright and the back of the base frame, it should just fit in both!
NOTE: Use the Gantry Alignment tool to make sure the distance from the edge of Gantry assembly at the back to the inside of the rear frame should
be 31.5mm. (Repeat for the other side.)
If there is any movement of the Gantry Alignment Tool between the Gantry and the inside of the back frame slacken the bolts and adjust the position
of the gantry, recheck and retighten after also placing the Gantry adjustment tool under the gantry and rechecking that it touches along its length.
Finally tighten all 12 bolts, quite firmly, but only using the Allen key provided. Check that all the bolts securing the stepper motor and the guide rods are tight.

mount using a wide bladed screwdriver or something
similar until it fits.
Align the top of the sleeve round the motor to the top
of the spindle mount.
Tighten the clamping bolt, do not over tighten!

the T nuts should turn to be vertical in the slots holding
it in place.
