Topic: extruder stepper
Stepper Motor - 68 oz.in (400 steps/rev) is that high enough torque?

Re: extruder stepper
How about this https://www.pololu.com/product/1209/specs for the Y axis?

I got a 60 oz in 0.9 atepper for my y axis for $11 or so on Amazon so that may not be the best deal. I don't know about the torque myself.
Re: extruder stepper
That torque doesn't look great for Y.
Re: extruder stepper
Nema 14?

Re: extruder stepper
You need a 17 for Y.
Re: extruder stepper
There must two sizes of nema 17 stepper motors, one short and one long.My current stock y stepper measures 42mm square x33deep. jagowilson , Can you give me a link to the one that you got off Ebay?

Re: extruder stepper
Here's the one I got, sorry it was $22 not $11. You will need 50mm M3 bolts to get it on the frame:

With 1/32 microstepping I have 352 steps per mm on Y. The motor definitely sounds weird with that many steps, for sure.
There are infinitely many sizes of NEMA 17s: the Nema 17 standard only defines the face plate size and bolt hole spacing. Length is not specified. Any NEMA 17 can be bolted to a Solidoodle.
Re: extruder stepper
I noticed that the color code order is different from my current order. How did you pair the wires?

Re: extruder stepper
That's weird I don't remember giving it any conscious thought. I just matched the colors on a 4 pin molex I had on hand from my RUMBA kit and it worked fine. If you are concerned they might not be the same hook a multimeter to all possible pairs. There are 2 windings so find the two pairs that generate voltage when you spin it. Pretty sure as long as you match the colors it will be fine but don't quote me on that- I don't want you to burn up a driver by mistake.
Re: extruder stepper
thanks, perhaps they just pictured the wires for effect, may not be the correct order.

Re: extruder stepper
I found that the vibration was caused by a bad stepper driver. I replaced it and no more vibration.
