Never connect or disconnect the motors or the cables when the board is powered.
Doing so will cause permanent damage to the board
The above board does not need to pin 16 grounded to enable the motors.
If you have this board, please follow these simple instructions to set it up.
The board was tested and set to 1.8A per axis - so no need to change the current settings
Place the board on a clean flat surface and made sure that there are no metal objects under it.
Connect the 4 stepper motors as shown below - make sure that you hook them up exactly
as shown below starting with the black wire, then Green, then Blue and then the Red
Here is a closeup view
Next, connect the power supply - making sure that the + wire from the power supply
hooks up to the + on the board - below is a picture showing the power hookup
Once the motors and the power supply are hooked up, connect the cable between
the board and the PC.
Next, install and run Mach3.
The following pictures show how to set up Mach3 to work with the board
If you don't have an emergency switch, set pin 10 to active low
Next, set the output pins as shown below
Next, set the hot keys for all 4 axis
Last step is th set the motor tuning - by default the board is setup for 1/2 step
at 1/2 step, using 1/2-10 screw, the correct setting is 4000 steps per inch.
At 3/8-12 ACME screw, the correct value would be 4800 steps per inch
If you plan on using foamworks, follow the setting in the picture below
Foamworks works fastest when the board is setup for full step, but the board performs best
when set to 1/2 step. Try 1st at 1/2 step, if you find out that you need more speed,
change the settings on the board to full step, and make sure you make the same change
in the software as well.
