Printer steppers dead, looking at replacements from Digikey

Here's a Minebea Astrosyn 23LM-K255-01 unipolar, 8-wire, stepper motor from Alltronics. From what I can gather the motor is NEMA size 23, 1.8 degrees/step (200 steps/rev), and rated at 1 amp. All that for $7.95 US each plus shipping/handling/tax. Given the additional information you provided, I would steer clear of those stepper motors you were contemplating from Digi-Key. They all appear to be 2-hole, flange mount stepper motors with various steps/rev from 20-100. And they're a lot more expensive, to boot. IHTH,

wow. thanks so much haytay. just sent an order for 3 of those.

again, thanks so much.

now i gotta go kick my friends a$$

I hope that those Astrosyn stepper motors from Alltronics work out for you, otherwise you'll be wanting to kick my butt, too. LOL

Find, beg, or borrow a digital camera, Rance and I would like to see some pictures of your PCB router. We need before and after shots of the stepper motors on your machine. Some pictures of a couple of PCBs you've milled wouldn't hurt either.


Your welcome,

And thanks,

ipod,

HayTay is right, pics would be great. In fact they are required. For some inspiration, take a look at http://www.nhcad.com/freecad . Look at the cd plotter and his small cnc mill. This hobby CAN be done cheaper than some folks will tell you. I think these small machines could be just as fun sometimes. Do something on your project every week.
