These pictures show how a fixed a stepper motor onto the y axis.
The third step towards cnc.
Im trying to keep the milling machine intact so that i can revert it to its orriginal state if needed.

Turning a coupling

Checking if it fits or not.

Getting some parts together for the motormount.

The 2 identical blocks with on top 2 m8 screws. The are there to check how much i need to mill away.

Suddenly i noticed that after my belt conversion, milling went alot smoother.
I polished it and the result was a near mirror finish.

Long distance view via the mirror stays intact. notbad.

Here I mill the shape out so that I never need to allign it again.

Some minor adjustment to the final "fit".
If I would drill holes alone, they will have some play, and i would never refit them perfectly again. This "fit" autoalligns it.

Some M6 tapping

Offcourse,1 hole didnt allign.

To place this "wheel" I had to completly saw off the savety cover of the lathe.

The shape of the stepper motor fits inside this hole perfectly, again alligning perfectly later on to the axle without extra work.

Testfitting.

Making some space for the coupler

Turning a round coupler out of a square block of aluminium.

The scratched circles have the same diameter. they will later line up and make work easier for me.

Turning away unnecessary aluminium.

In the holes I will fit m3 wires.It looks like a bad way of coupling but it works fine.

Drilling the holes for the stepper motor.

Testfitting the holes.

Here you can see the m3 bolts. it allows alot of "play" on the design but it has no extra backlash.

A front view without the motor fixed.

The coupling needs to be fitted pretty tight to the axle of the stepper motor.

Mounted onto the motor axle.

The fnished top view.

Finally finished. now onto to the stepper controller and computer control.
