Steppers for RRP Mendel
October 01, 2014 05:50AM
So I'm building a RepRapPro Mendel from bits and the frame is all done, I have pulleys, ramps, heated bed etc... only things I don't have are steppers and hot end.

They sell the JK42HS34-1334A stepper which are 30oz 1.3a 1.8 degree for £10.70 each plus shipping with shipping each motor works out to be £11.30

I have also seen these [www.aliexpress.com] which are 39oz 1.3a 1.8 degree and they work out to be £10.00 each if I get done for import duty or £7 each if I don't.

Thoughts?

The ones in the link look good to me tbh, electrically 1.3A 2.4ohms 2.8mH. Exposed shaft is 22mm, better than some which have like 13-14mm and would hardly fit a pulley.
The JK42HS34-1334 found a link that said 1.33A, 2.1ohms, 2.5mH, electrically same thing or marginally improved (lower mH), shaft 20mm. I would go with these ones, but the difference is rather minor.

Thanks for that I've ordered some.
