Does this help
Hi guys, I have pulled out 3 stepper motors from old HP laser jets, the motors seems to be very powerfull, i suppose they are functional, but since i do not have a diagram, i cannot wire them up to my CNC driver, there are 6 leads coming out of the motor, but not sure if it is a unipolar or bipolar,
i would really appreciate it if you can offer some help here.
Thank you guys,
now assuming that i could figure out which lead is which, A1, A2, B1, B2, i am left with 2 common leads, these 2 leads do not get connected?
Thank you very much for your help, i was able to connect the 4 leads to the driver, the motor locked, which means it is operational and produced some noise.
connecting the driver to the breaker is not difficult, i guess i will just connect 2leads (step+direction) to the breaker.
but I have to setup MACH3, pins and ports and so on, this is like chinese to me.
your help is greatly appreciated
add a GROUND connection from the breakout to the driver.i guess i will just connect 2leads (step+direction) to the breaker.
Look at the instructions for your breakout board (or pin assignment) in order to configure Mach3. You need to know if the signals are active high or low and the pins used for each one.
Thank you very much,
I hope you appreciate my frustration, I am through with building the structure for the machine, I have the motors, the driver and the software, but cannt jog the damn thing.
Taking 1 lead from the driver to the breakout ground causes the motor to move CCW, I guess this is not right.
I followed pins on the driver, but cannot figuer out ports to assign on MACH3.
Thank you again for your help
Look at the following two screens under Config Ports and Pins:
Thank you very much my friend, followed your instructions, got the motor moving CW and CCW, but the movement is kind of sluggesh and slow.
the motor produces little noise, but when I statrt MACH3 the noise becomes higher, and the motor moves one step back and forth, with smaller motor the motor steps CCW.
I got the stepper drivers and the breaker from Rout Out CNC based in the UK, you can follow this link for driver's specs:
As for power supply I bought an AC/DC converter off the shelf of a hardware store, you can get from 3 volts upto 12volts, when i get home i can give you how many amperes (sp?) does it give. I am running the motor on 4.5 volts.
Execuse my ignorance for all of this electornic staff is new to me.
thank you very much
