Hi to all.
Its been a few years sincee having to make any repairs to my cnc equipment.
I am going to replace the 3 axis driver board in my Milling machine.
When I used to power it up the steppers would buz and lock up and all axis would work under comand.
Now when I power it up they buz and lock for about 1 second, then all goes silent and they are all not locked and it wont work.
Having convinced myself the Driver board was at fault I purchased a new 3 axis driver board.
I have been reading about the stepper wire conections, My steppers are powermax and have a plug rather than wire tails coming out of the motors,,I am not convinced the wires follow any standard layout,,when un pluged the motor has 8 pins all are linked to gether in pairs and only four wires come out of the plug,
I have identified the pairs aa bb..from what I have read so far on the net seems a bit odd when it comes to sorting out A- & B-,
I have been unable to find any Powermax pin info, is it really ok to just place them in A,A- and B,B- without knowing the polarity,, ill it not harm something, and how will I know if all is correct.
Many thanks
Berty
