Hey guys,
I just got a 3-axis TB6560 board in from China and am having some issues with voltage. In a nutshell when my board has power and is connected to the parallel cable of my running computer, the stepper motors start vibrating and getting hot.
- I am using 3 NEMA 23 motors rated at 3V ~1A (From an Old Printer)
- I am using a 19V 6.3A DC power source (from a laptop)
I checked the x,y,z terminals and they are all getting 19V at this point..
Why would the board be sending a full current to a motor that needs 3Vs?
Any help would be appreciated.
