[Swansea Hackspace] Stepper Motors

[Graham Owens]

If noone else is interested, I'll go halfers with you Ceri, but it would have to be on/after 28th as that's when I get paid. 5 motors each?   I'm not fussed about the feedback, buzzing motor usually means bad config.  Look at the Gerrit's motor, and he sorted that, was just configured wrong when we had the attempt at it.  I believe its working fine now since he looked at it again?

They don't have the same number of steps per rev as yours! ;-)

Wow, that’s a third of what I’m currently paying for NEMA 17 stepper motors:

Unfortunately my little university grant doesn’t allow me to buy equipment off eBay :(

Is anyone interested in getting some stepper motors,


I have found:


http://www.ebay.co.uk/itm/Promition-nema17-stepper-motor-48z-in-1-7A-RepRap-DIY-3D-Printer-CNC-machinery-/321307263813?pt=UK_BOI_Electrical_Components_Supplies_ET&hash=item4acf67c345



£66 for 10


£6 each !!


I want 4-5 for my next printer,


Any one found a better deal - I am fairly sure more than 1 Amp is needed for good positioning.


Cheers




Ceri
