General Mach Discussion / Re: Motor Driver issue

@Tweakie: Measuring it the old fashioned way using continuous mode on dmm.

@joe: yeah we had a PCI board. were trying to get our system running with the usb board. No output using USB->switch back to PCI. Using a really generic PC with xp installed on it. Have not checked DriverTest.exe. will do
But the question arises if it was a misconfiguration on the port and pin nos, why would i experience it on the arduino as well?

Thank You

So what could be the possible reason for me getting a direct short between the Pul- and Dir- pins upon powering up the motor driver.

P.S.
as mentioned before, when the power is disconnected, the 'short' is no longer there.

Have tried all that. I think there is probably an issue with the ports and pin nos that I am selecting. Do you know what the correct port and pin nos might be for this board.

Also regarding the dir and pul pins being continuous. Is that supposed to be, or is it just something going wrong inside the motor driver

I have a PCI port mach3. Whenever i run the code, first of all none of the motors run. Secondly I notice that the pulse pin and Dir pin on the motor driver appear to be shorted(continuous).
To verify i even tried to run the circuit with an arduino. When i upload the code now, still the pulse and dir pins appear continuous. However when i remove the connections and then try to test it, they are no longer continuous.
Pretty sure there is something really basic that i am missing out. Can you please help out.

P.S. attached figure shows connections followed

By short i mean that they are continuous. I tested it out with a multimeter. And as far as a different board goes, I am stuck with this one currently. If it turns out to be completely hopeless, then I will be moving onto a different board.

General Mach Discussion / Pul and Dir pins short
« on: September 12, 2018, 06:48:51 AM »
Hello

I have a USB mach3 board. Recently I have started facing the issue, that the Pul and Dir pins for the X, Y and Z axis are short on the board. Also the A axis pins are not short. Is this how it is supposed to be or is my board messed up.

Note: I am only using the X, Y and Z axis for my CNC

Thank You

Thank You

Now i simply need to figure out the pin and port nos for the 4 input pins. If you come across anything which might indicate the answer please do let me know

Is it feasible for me to simply ditch the limit inputs and simply provide all 3 axis homing signals to individual pins.

Are there any issues that may arise...

There is the following picture provided. However I am unclear as to the working of connecting all the home switches to the same pin and all the limit switches to one input.

There isn't a manual describing the pin nos. The plugin is installed. I am able to control all the motors, however when the motor reaches its limit (i.e. home), even though the limit switch turns on( gives low voltage signal), the motors do not stop
