Redesign of JGRO in Denmark.

Okay, so I decided to buy the 4AUPC Chopper Driver Board Kit from hobby-cnc. http://www.hobbycnc.com/4aupc.php. I figure it's hard to beat the price by building it myself. Espcially since i havn't got anything to to etch the pcb-board with and I get a proven driver with no childhood diseases.. Im hoping it will arrive before my vacation ends..

Forget the round motor it looks like a 5 phase motor (0.72deg / step) Torque in the region of 104oz/inch. Not very strong in this case but 5 phase motors are very smooth. Its also hard to find a DIY CONTROLLER.

Your torque for the square one is correct.

I guess I have to find some more copiers then..

So today i tried getting some more stepper motors from this copier service technician. But I forgot to check the copier to see if it was 2-phase or 5-phase. So of course I wounded up with another 5-phase 5 wire motor.. Sux.. :frown: I guess I'll have to buy the last two from http://motioncontrolproducts.co.uk..

I read the specs for the controller I bought and it actually says that it will run 5-wire motors. But not the 5-phase ones? anyone?

Okay. Time for another update. Today i went to my local blacksmith to get some steel made for running the x-y-z sleds on spindles.
I had these three made. I will make threads in the small hole to run the threaded rods and thereby pulling the sleds.

So today i got the y-axis on there, after a lot of fiddling an redoing


I wonder how to adjust it when I'm done? Is there a good approach?

Today I tested my soldered together my new hobbycnc-kit. Didn't take too long, and even though I lost a 1uF capacitor I just substituted it with a 2,2uF that i fortunately had lying around.

But everything works perfectly. I adjusted the amperage for the stepper and hooked it up.


I used the free and open source EMC2 program to drive it and the xyza-stepper configuration and it worked without any configuration! Excellent
