3, Installing the top limit switches and the top frame:

Mounting the top limit switches and the top frame:

3D printer, assembling and setup

Now it's time to move to the upper part. Top limit switches and top frame. The plastic bag has a number that indentify it, very convinient.


3D printer, assembling and setup

The cables from the switches run through the pillars, do not get any bent on the cables


3D printer, assembling and setup

The cable come through at the bottom, there is holes prepared to let the cables connect to the pcb board.


3D printer, assembling and setup

I mounted the switches in the same direction on all pillars to have it symmetric, maybe good.

This didn't look nice to me. A very sharp edge at the pillar that can cut through the cable.


3D printer, assembling and setup

Looking in my boxes what I have laying around to fix this. Found plastic tubes that I could use. Cut six 20 mm tubes.

This is the top frame where the switches are located. Put on the protection tube.

At the other end, the bottom I do the same. Very limited space, don't let the cables be twisted. See how the cable go through the hole.


3D printer, assembling and setup

Same problem with too long screws at the top frame also, easy fix with washers.


3D printer, assembling and setup

With the switches in place I can mount the top frame. First I tight the top screw, it acts as a end stop for the pillar. Take care to not squeze the cable, limited space here.

Second I tight the side screw that hold the top frame.
