Hi Guys,
I have bought myself a bipolar microstepping control board. I want to use this control board to move a epson 600 stepper motor. Even though this will be a microstep with a small stepper motor it will be a big step for my CNC Dreams. I have taken a power supply out of an old PC. There is 12V and 5V outputs. I hope I can use this to run the motor.
But before I go blowing up stuff I wanted to show how I'd set it up and then if there are any major mistakes maybe they will be pointed out before I make a mess of things.
Ok so in Mach3 I have set the outputs for the x-axis to
ENABLED has a green tick
STEP PIN# 3
DIR PIN# 2
DIR LOWACTIVE has a red x
STEP LOW ACTIVE has a red x
STEP PORT 1
DIR PORT 1
So I will connect my parallel cable from my pc to my breakout board and the step signal should be in pin 3 and my dir signal should be in pin 2. On my breakout board there is a 5V input and a ground. There is also a VDD (it looks like that anyway) and a ground. What am I supposed to connect to this. Im not sure whether I got literature with the board but I cant locate it if I did.
On my motor control board I need to give it a ground and +VE Input voltage. I was going to use a 12V input from the power supply . On the power supply (see pics) it gives the DC output voltage and currents. The model is PS-230WRE. Is this a 230W power supply? If so there is a +5V which gives out 23A, +12V which gives out 9A, -5V which gives out 0.5A and -12V which gives out 0.5 V. Which 12 V am I looking to connect to power the motor? 9A seems like a lot for a small motor and the board is rated for 2.5A 30 V Output drive Capabilites. I have kind of answered my own question there but clarification would be nice. Just for interest sake does anybody know which PC components run off which voltages? Also on the control board there is a pot which needs to be adjusted for VREF. How do I find out the Motor Current for the motor in the printer. The table is TAble 2 in the pic..I have looked for datasheets on them before and could not find them... There is a pic of the table included.
Wiring up the motor coils and step and dir should be straight forward after that.
Hopefully someone can tell me whether im on the right track or not...
Best Regards,
