Base assembly (ballscrew)

Now slide the x carriage over the x axis rail and take the side plate that you just finised and that has this orientation:

Attach it to the x axis c beam with 15mm low profile screws.

Also put in the ballscrew into this plate – with the 8mm end going through the hole that is made for it.

At the 8mm side, use the same setup as you did for the Y axis:

And at the other side, with the M10*1 thread, also mount the x axis c beam to the side plate with 15mm low profile screws and have the M10*1 thread go through the hole that is made for it.

Put in a 10mm ID 16mm OD bearing to support the ballscrew:

Now put on the little 3 printed support and a M12 spacer, to keep the pressure from the collar on the outside of the bearing:

Put on a trust bearing:

And the M10*1 nut and flexible coupler:

Now we have the structure:

At the side of the X axis, and at the backside of the machine, also add the stepper motors, with flexible couplers. Instead of the 40mm spacers in the picture below, we needed a bit extra space for this tensioning system, and we rather will put a 40mm + 6mm + 6mm + 1mm + 1mm set of spacers between the stepper motor and the plate:
