Need help with stepconf set up was created by BX-CNC
Hi all,
Right now I am testing my first CNC machine. I can already toggle the machine power on and off on LinuxCNC to lock or unlock the motor of my machine. But when I press + on y-axis (the axis i am testing), there is still no response. I think it might be the motor driver problem. Can somebody help? Thanks a lot!

This is my motor driver.

This is my motor.

Hello friend
You can use an oscilloscope on the pulse output of this board, use the test axis feature in the image below

 

I recommend leaving the drives activated at this point, as remote activation may not be enabled in this test.
I also recommend not using the board indicated in your link, as it is not reliable, it does not have electrical isolation, and when the system loads it activates the outputs by itself, making the machine move before the releases and safety.
I recommend using the 7i96s electronic board, which is very safe and high quality.

Thanks for your response.
Do i need to change the parameters like step time for drivers in the first page pf stepconf? I think thats the main reason of motor not running. Since i can toggle the machine by clicking on PC, i think breakout board right now can send the signals.

You need to synchronize the number of pulses from the hardware with the software. The photo below has the adjustment that increases the number of pulses.

 

The software has an initial screen to change the pulse speed. There must be a calculation for this, but I don't remember it at the moment. But you can try until you get the movement and then adjust it for the best performance.

Unfortunately this board has serious speed limitations, as it connects to the parallel port it is very slow and you have to adjust the Base Period Maximum Jitter according to the type of PC.
There is a latency test, which is important to check.
