![]() ![]() So long as they each move, you at least know the drivers aren't burned out. It should advance that specific axis by one microstep each time you touch the step pin to ground. Mgaxyff MACH3 5 Axis Stepper Motor Controller, MACH3 Interface 5 Axis CNC. Tie all grounds together, tie stepper enable to ground, and tie one of the direction pins to ground, then touch its step pin to ground. 5 Axis CNC Stepper Motor Driver Controller Breakout Board at. If you don't have an arduino, you can just use some jumper wires to test it. Step 3: Use the following code to open COM1 and send a 'b' character to the port. Step 2: Register it with the operating system using 'regsvr32.exe mscomm32.ocx' at the command line. You'll need a parallel port on your computer (you can add a PCI parallel port card to a desktop if you don't have one on yours)Ī cheap way to test it would be wiring an arduino to a DB25 port and throwing grbl on it. Step 1: Find the file mscomm32.ocx and put it in your windows\system32 directory. It's a parallel interface (not serial as the other user suggests), which means you can use mach3, linuxcnc, or any controller that allows for parallel. If it doesn't come with a mill, you can test it by plugging in some steppers and powering it up (in that order) Looks like this controller is common, and is often paired with a china mill, mini cnc 3040. Huge silkscreen text in the fourth picture says "jp-382a". When you want to identify boards, just start plugging any model-number-looking text into google. ![]()
