Belt Driven Z-Axis Ender 3

For more information see Info.txt

Attention!

I’m not an expert and 3D printing is my hobby. So please be careful when you rebuild your printer and don’t just go ahead. For my printer the parts fit perfectly.

Everybody bears the risks of a modification himself.

All parts can be modified as you like.

First things first:

My Ender 3 always had problems in the Z-axis, which were caused by a bent spindle. Therefore I decided to convert the Ender to belts in Z as well.

This conversion also solves the problem of a hanging x-axis on the right side. Because of the two belts, the two sides not only run synchronously, but can also be adjusted very precisely.

So if you have all these problems with the x-axis, this is a good solution.

3d-printed parts:

The orientation of the parts is random. Please find out the optimal alignment by yourself. All parts can be printed without support. All parts must be printed only once, except 4x ‘Clamp’ 6x ‘Spacer1’ 6x ‘Spacer2’.

Wall line count: min. 5

Infill: 50% or more

0.2mm layer height

Instructions:

When mounting the X-axis on Left1 and Right1: The profile protrudes 5mm to the right, the distance to the left is 43mm to the edge.

Then mount all parts as shown on the photos. Spacer1, are the front, Spacer2 the rear spacers of the V-Slotwheels.

Three of the M5*40mm have to be shortened to fit the Carraige of the Hotend (about 25mm).

The Belts need a length of 88cm and are clamped flush.

The length of the rods depends on the position of your motor, you have to measure it yourself.

The steps/mm have to be set to 80.00 for Z. If your Ender 3 has no eprom, write ‘M92 Z80.00;’ in your start code.

Done!:) Good luck and happy printing!
