General Mach Discussion / Re: Help, X-Axis only moves in one direction

Yes,

I only have one card, which I attach all three motor to.
I apologize, I am new to CNCs and Mach 3 and am probably not making it easy for your guys to help me.

General Mach Discussion / Re: Help, X-Axis only moves in one direction

The x-axis stuttered, so then I plugged the X cable into another motor, then the y-Axis motor started stuttering.
Problem doesn't appear to be related to the motor.

I then swapped Cables, using a previous good cable and a "good" motor into the x-axis of the driver board....Still bad stuttering.
Problem appears regardless of what motor Or cable I use.



Hood, when you say swap the drivers around, do you mean for me to take out the driver chip from my X and put in my Y chip?
Because I also replaced the X Axis chip in the driver board, but this didn't help ether.


I also played with the motor pulse direction values & confirmed that the keyboard is mapped correctly for jogging direction, after all, it sometimes does go in the right direction.

Update:

The x-axis does go through brief moments were it does move in the right direction, but then stutters and doesn't move to the left again. I noticed that  when I first turn the system on ( before I have start up mach 3) that the X axis is humming and randomly twitching. This isnt happening to my other to motors. I then plugged in on of the other motors and it did the same thing. This isnt a motor or cable issue.

I loaded up Mach 3 on another computer at home, added a fresh HML file and the the same thing still happens.

At this point, I am almost certain I have a Driver Card Issue.

Going to send the card back for them to look at.

Thanks all

General Mach Discussion / Help, X-Axis only moves in one direction

Hello,

 I have a issue with my X-axis that is giving me fits.
 When I try to jog the axis to the left and right , it always moves to the right regardless of what Key I press.I cant get it to move to the left.The other axis controls work just fine.

I have done some initial trouble shooting and have confirmed it is not the motor, the cable, and I just recently replaced the Chip for the X-axis driver  thinking this would fix the problem........no such luck.
When I test the Mach 3 driver test, it sometimes says pulsing too fast. Not sure if this is related or not???

I am running Windows XP
Lastest version of Mach 3 ( Purchased the license)


What should I try next?

Resolution:

I turned off all power management controls in Windows XP that placed the system into Hibernation, etc.
After leaving the system on for 24 hours, I still have control of all axis at this point.

Thanks!

General Mach Discussion / X- Axis times out

« on: May 04, 2010, 09:14:01 PM »

Hello,

I just purchased Mach 3 and I love it so far, but have run into 1 issue.

When I 1st turn my computer in and fire up mach 3 and the CNC everything works fine.

If I leave everything running and come back several hours later, the x-axis will jog for a second, then just time out and becomes unresponsive. Mach3 still shows the axis moving (when I try to Jog), but the LED indicators on my driver Card stop lighting  like its not getting a signal?

The other 2 axis seem to be immune from this issue and work fine.
My only work around it to shut down and reboot each time this happens.

Not sure what these symptoms point to as a possible issue; Computer,Mach3, or driver board?


Thanks for any suggestions.


Tom
