To moderator, I apologise if this is not allowed or should be posted elsewhere.
If anyone from (Australia only) is interested, I have this controller I built a couple of years ago and some steppers I'm not likely to use, and I need a stepper with a little more grunt to drive the X axis of my new mill I plan to build, and the size of this mill is dependent on the stepper I can scrounge up.
The controller board (CNCZONE's tachus42's 3 Channel Discrete Unipolar Baord) project can be found here ( http://pminmo.com/3axis/3axis.htm ) it works very well, at the time I built this controller I didn't know about the toner transfer method, so the tracks on the PCB were all drawn out by hand takes some patients and a steady hand but it can be done, I also built the chopper to go with this controller but couldn't get it to work properly and has some minor damage to one of the tracks but it isn't a big deal can easily be patched.
All the information I have on the stepper motors are as follows.
DC 4.08V 1.7A
DC 4.08V 1.7A
1.8DEG/STEP 3.7V 1.0A
I also have a few other stepper motors which could be mixed and matched in the deal to suit your needs as shown in the photos I also have a few other bits and pieces salvaged from old photocopiers and printers , I am not interested in dollar value just a happy outcome for both parties.
I'm only willing to send on these items once phone contact has been made and preferably received the item that was agreed to be traded, also I think postage insurance would be a good idea.
