xylotex 4 axis board and unknown stepper motors

[abigroot]

I won some stepper motors on ebay and I am ready to hook them up to my xylotex board. Problem being I don't have any info on them. The only thing I have is that they are a 1.8 degree .4 OHm four wire motor. The only markings on them are as follows and beear in mind that these look like "stickers" on the end bell of the motors.

1 motor # 127K44370 and STP-58D4002-03 and 19230g

1 Motor #127K44191 and STP-58D4002-01 and 06231

1 Motor #X02-58d4-0010 and 25420.

Any help would be helpful. the wire ciolors are the same on all of the motors and are in this order (From left to right with output shaft facing you) Red-Brown-Yellow-Orange. If anyone has some similar set-up, could you let me know how yours is set-up. I plan on using Mach3 to control all this.

DOn't wire them up unless you are SURE you know the correct way. Miswiring the motors on the Xylotex will result in it's death.

There are several good tutorials on the web about testing motors to determine the coils/phasing. Stepperworld.com has a pretty good one.On the xylotex board,you MUST follow proper setup procedure,or you might damage the board.Be very careful,check all connections,and power supply polarity,and reference voltages ,set them a little on the low side at first.Then re-check them all 4 or 5 more times exactly like the instructions state. Use a quality voltmeter.Be very careful,then re-check the Vref,hook up the motors....it'l work,Did you check the reference voltage?

I haven't checked the reference voltage yet (I just got my board this past week) I will check out stepperworld.com and see what they have. I have already paired them up using an Ohm meter, but thats about it right now.

COOL!You have it half whipped.If you label the wires paired per coil
a1-a2,b1-b2 the proper connection to the board should be similar to: a1,b1,a2,b2. if the motor runs the wrong direction,switch a1,a2,or b1,b2,but not both.(or change it in software) I hope this makes sense.What ever you do, be sure to follow the procedures in the correct order of events,and never shut off power to the motors while they are running ( I understand this will fry the board. )or adjust the Vref with with motors or motor power connected.
