Help! I Am Having Problems Hooking Up My Pulse Generator To My Driver.

Hello,

Hello,

I have a single stepper motor setup with a Phidget Stepper 4-motor Unipolar stepper driver board and a CNC STEPPER SERVO MOTOR STEP Pulse Generator & TESTER I bought off of Ebay from Hubbard CNC and the instructions are not too explicit for the beginner. My The motor is hooked up to the stepper driver manufacturer correctly and running from the Usb and Program but, I want to be able to control the motor without the use of a computer hence the pulse generator. My problem is the stepper driver has +ABCD+ written on it (a six wire setup I am using by the way) and it has a 2 screw block separate from the 6 screw block and it's marked G and + and the pulse generator has 2 blocks: 1st block has 2 screws in it and they are marked +5v and ground (which connecting these is not even mentioned on the Ebay page) 2nd block has 3 screw locations and they are marked Pulse, ground, and 0/5v. The instructions for the Pulse generator is telling me to hook up the step, direction, and signal grounds. I am just lost and writing this at 1:00am after messing with this thing for several hours. Any help would be appreciated.

In the picture on eBay it looks like the connector labeled +5V and Ground is either for connecting a direct 5VDC supply rather than using the Tip & Ring connector for a wallwart supply or it is a + 5VDC output to support other device. Since it came with a power supply that plugs into the Tip/Ring input do not use the +5/GND connector.

The other pins should lineup as below:

Test brd. ------------>Stepper controller

Pulse---------------> Step input

0/5V ---------------> Direction input

Ground--------------> Ground or 0V point

From the description it sound like the board will output a pulse train that can be varied in pulse width (on time) and frequency (speed) to suite your needs. It also seems like it will also produce an output whenever it is on.
