Update BOM / ease procuring of stepper motors #10

Closed dirkx closed 5 years ago

dirkx commented 5 years ago

The currently specced/linked stepper motor link in the bom has a fairly short axis (12.5mm length).

Actual round axis length can be up to 22mm to still clear the left/right feet.

So would suggest updating the BOM to allow up to 20.8mm of shaft length.

And perhaps clarify that the mentioned 20mm body/enclosure size is not that critical.

As that means there are many more stepper motor suppliers suddenly.

The stepper motor must be a NEMA14 with 5mm shaft.

The height of the body of the motor must be 20mm or less to fit the standard cover. A taller motor is fine if you don't use a cover or design a deeper one.

The motor shaft on the one listed in the BOM is rather short. I can be up to about 20mm long.

I have linked this issue to the BOM.

Closing issue.

Here is an amazon link for a motor that should work.
