Trouble with setup
« on: September 08, 2007, 06:36:35 AM »
It should be right forward. When I was finished and connected to my PC and started Mach3, nothing happened.
I have my motors on my desk, just want to see them move when I run the “Roadrunner” G-code. I was quite disappointed when I just heard a ”tic” from time to time.
I tried to change the pins for output, but no. Nothing. I have tried to change many variables. Nothing happens.
If ther is some one “out there” with the same package, let me hear from you.
I have to mention that I could not use the power supply that was set up with the package. In Norway we have 230V. I bought two new power supplies. One 24V, 1.9A and one 6V supply (this one can be regulated down to 4.5V and up to 7.5V). When I measure the 24V supply the meter shows 23.5V (is this critical?). In the specs for the breakout board it says 24-40V




I really hope someone can help me.

Best regards

In the wiring diagram "KL4030 driver" you are showing pins 2 and 3 wired down to your driver card from the breakout board. You do not have a connection for the signal ground connection (the pin between pins 2 and 3). This ground pin is from the computer and connects it to the rest of your circuit, so should be connected somewhere.

One my cards (Stepmaster) there is a signal ground connection to do this, on the driver card.
Not me driving the engine - I'm better looking.

This setup is what I found on Keling Incs homepage.
The pin between pin 2 and 3 are 5V+. I put a wire from this pin and to the driver instead of from the 5V power supply. I also did some changes i the Mach3 setup an d now it is working fine. I don't know if it was the wire or the Mach3 modification that did it. But it works.
