Question #: 4676

Question: I have a CNC Machine from China, and the Breakout Board is not Labeled. Is there any way to test the board using Mach3 to find out the pin designations? db25 bob

Current Solution

(These steps are to be taken with precaution, due to the fact that we do not know the model or manufacturers specifications for your BoB)

Here is a link to our CNC electronic videos(

Try using this to compare the one you have to our older model version BoB, try setting up your X-axis to work wiring it to your driver and motor, and power supply.

I would recommend trying to contact them if possible to avoid any serious damages to your product.
