Anyone suggest a replacement for a HY - 200 -3437 - 460 A 8?
There are some used available, but not in the uk, so not readily available.

Looking at the Gecko guide to steppers, there is no layout that can give continuity over 2 pairs in an 8 wire setup, so it looks like the stepper is junk.
Can I just swap it for new, replace the Gecko's and I am good to go, or is there something else I should check? Very nervous about the magic smoke.

They are all separate, so is is significant that there is continuity between the colour pairs, ie red/red and white, but then there is continuity between two of theses pairs...
thanks for the help by the way.

Ok.
Y to Y/W =1ohm
Y to R =1
Y to R/W =1
Y to O/W = 1
B to B/W =1.3
R to R/W = 1.3
O to OW = 1.3

Thanks Hood.
I did continuity, if that isn't enough I can ohm, but ;
8 separate wires,
Continuity between
ORange / orange and white
Black / black and white
Yellow/yellow and white/red/red and white.
couldn't compare with other axis, the 8 are wired in pairs on that.
any clues?

Good to see you guys.
Briefly, after swapping some bearings, my x axis only made a quiet whine, and no movement. Checking I found about 4 wires had come loose from the choc block connector to the motor. Putting them back in, one touched the framework and I realised i had left it energised when there was a crack crack from the direction of the control box.
Checked the fuses,  They were ok. Swapped the Gecko's about to see if one of them was the problem. Crack. Magic smoke from the good Gecko moved to the X axis. So now I am 2 Geckos down, call it £250 on the night, and don't know what the problem is or how to track it down. Suggestions please?
And it's always when there's a big rush on, and also, I can't seem to think straight, or I would have tested the suspect drive Gecko on another axis...I think it's panic.
suggestions welcome.

34's then, and using a resistor, so 1-5 on 9 on 10 off.
