I need some help. I'm in the middle of a large project for a client and something is wrong with my controller on my expanded C-beam machine. Im using a cheap arduino pronteer shield and arduino clone. I have dual y axis motors and only one is being driven. I checked all connections, replaced the polulo drv8825 drivers three times, I also swapped drivers and motors around. I still can't get the Y axis port to move. The cloned port works ok though. So I think something is wrong with the board itself. I was hoping to fix it easily without buying another board. 1. Can I run two nema 23 motors off of one drv8825 driver? 2. If I have to buy another board, I'd was looking at the cnc xpro V3. But it always seems out of stock. Does anyone have one they could sell me? Or is ther another site I could buy one from that has it in stock. 3. Is there any way to hook up an external controller to my cloned axis that is working? Please help, I'm on a tight deadline and need to get this resolved. Thanks!
