I have a several Arduino components that are connected to a stepper driver and then to a stepper motor. My stepper driver has broken and is not available anymore (R1025 Step). I did get a new driver (ST-M5045) but it seems like the connections are a bit different.
Frist image is how I currently have it connected with the R1025 Driver. The second image is the new driver with the stepper motor only connected. Did I choose the wrong driver for my application?
The GND on the stepper drive goes connected to my Arduino screw shield GND terminal. But I do not have that on my signal terminal on the ST-M5045. I would think that my connections would go:
GND = ?
COM = Pul - & Dir -
STEP = Pull +
DIR = Dir +
I gave this a try, the stepper LED light came on but my stepper motor wont budge. Below are some quick sketches I made, hopefully they make sense. The first one is what I had originally, this worked until my stepper driver broke.
When it comes to these kind of items, I'm very ignorant so I do apologize. I'm trying to learn as much as I can. I'm a bit confused on the pulse & directions. Are you talking about like the dip switches on the sides?
Only you can take care of confusion. How was your original driver configured? Match it to the new one. Do you have the documentation for each one and does it explain what switches effect the step and direction functions?
etween pul+ and pul- is a optocoupler connected in the driver thats all so connect the pul for a pulse and do the same for DIR maybe change the time for a puls to 1 msec as tne driver waits for a decent signal
I was able to find some documentation online, and I did change the some of the driver settings using the dip switches. After a night of research, I sort of understand the pulse and directions. I was able to get really close to what I had on the previous driver, as far as speed and steps.
