The first part of the build sequence it to assemble the Y-Axis

Select the bags that contain the parts to build the Y-Axis. There are aluminium extrusions (bottom), some black aluminium plates, some round rods, various orange and black printed parts, nuts, bolts and various fixings. These are all in marked bags, showing their size, the number of each part in the bag and are easy to sort out.

Having cleared sufficient workspace it was time to begin. The instruction book was very clear and led one through each stage in minute detail.

Having selected out the parts required - all the Y-Axis bags of components…

Lay out the parts - the upright part of the frame showing the PRUSA name, the longer and shorter extrusions and the 16 10mm bolts.

Bolt the short extrusions to the back of the frame and the longer extrusions to come out the front.

Then the front and back black painted plates with their bolts.

With the base of the printer now in place it was time to check that it sat firmly and squarely on the desk and did not rock around. All seems good.

The Y-Axis rods support brackets, front and back. Fit the square nuts into the parts as shown…

Y-Axis rod supports fitted

Now to assemble the belt-idler pulley

The Y-Axis motor holder

The Y-Axis motor holder fitted

The Y-Axis motor is now fitted to the printer chassis

Below:

The four stages of assembling the Y-Carriage. Clockwise…

Mounting the three linear bearings and the Y-Belt holder, then carefully inserting the rods through the bearings and mounting it onto the printer chassis.

Below: Fit the Y-motor pulley, then fit the toothed belt and gently tension it.

There it is, the Y-Axis section is built. The test is to slide the Y-Axis bed back and forth to check that it runs freely and smoothly. That took 1 ¼ hours to build
