Stepper Motors

Hi guys,

Wally calls for 40mm motors, but I can only seem to find them in 48mm (with reasonable shipping to Canada). My question is: how difficult would it be to make the parts work with 48mm motors?

Alternatively, does anyone happen to know a place that carries the correct motors and will ship to Canada?

Thanks,
Jeremy

Stepper motors Overall Dimensions 42mm x42mm x 38mm

http://www.ebay.com/itm/5-Nema-17-Mineb ... 27d28c692c

only 38mm but that works

I don't know why Wally needs 40mm motors
they just hang down below motor mounts?

Use whatever size you like. I have very specifically places holes to let the wires go from the front to the back and then down guides in the back board. It would be a simple matter to drill a hole and use any size that you want.

Just wanted to verify a few things about stepper motors -

Prototype uses the QU-BD NEMA 17 extruder motor for all four motors?

If this is true, then my understanding is that the motor is a WANTAI with custom windings, higher voltage rating (less current) and more torque than the typical stock motor of that size.

Does Wally X/Y or Z benefit from the extra torque?

There are motors from WANTAI or ROBOTDIGG with same frame length but lower voltage/torque that are available on ebay or aliexpress for about half the price, if you can wait for shipping from China.

Those should all be great.

Is there a specific shaft length that we need for the X and Y steppers? I feel like I heard something about a longer shaft needed but haven't been able to find that information again.

I can't imagine the shaft length ever causing a problem.
