DIY Moveo Part 9.1: Module 3

This week’s blog post is the second part of the part 9 assembly. We’ll start with the step 4 and finish the Module 3 in this post. If you don’t have read last week’s post, check it out here.

DIY Moveo Part 9: Module 3 – DefVar

The 3rd module does not come with bigger issues. It was quite convenient to set everything up. In the last part, I made a mistake where I glued the M3 brass inserts into the hole. Now I knew that there are heat inserts. And with some head, it is straightforward to install them. Although I have to gl…

Preparation

Step 4: 3M2 Assembly

We have edited the 3M2 parts (3M2C & 3M2CC) to fit our stepper motor inside. For the detailed changes, have a look at hit blog post:

DIY Moveo Part 5.1: Changes 3M2

As mention in part 5 we need to change some files for the new motor. The Motor is 6 mm deeper than the original. We have multiple options to get more space for the engine. First, we can lower the “basement”. Second, we could raise the “roof”. If we raise the roof, we have to […]

Because of the modification, the motor fits very well inside the 3M2C part. Note that the rod is threaded. This is important for mounting the 4th module on top of the 3rd.

So fare, it is a straightforward installation. Now thread the cable through the 3M2CC part and screw the 3MC and 3MCC parts together.

After this, we finished this step.

Step 5: The Belt

You need a piece of belt with the length of 44.6 cm. The basic strategy to mount the belt is the same as in the belt mount step from module 2. First we insert on side into the belt mount. Then thread the belt through the hole and around the pulley.

Thread the belt through the hole again and align the 3MC assembly and the end off the belt on one side

Now pull on the belt end and slowly move the 3MC assembly to the installation point. The mount for the end of the belt should be accessibly the hole time. Now insert the belt into the mount.

Insert the bearings and push the rod through the hole and through the 3MC assembly. With this, you can easily mount the parts togehter

Done. The belt should be mounted, and your result should look like the following picture.

Step 6: Brass inserts

To insert the brass inserts, you need a soldering iron. I heated my Iron up to 572 °F (300 °C). And put the brass insert on top of the tip from the iron.
