I have installed Mach 3 and from the moment i open the programme all my motors turn a step every few seconds and I cannot for the life of me stop them.

When I run a G code it all works fine but a few seconds after the g code is finished the motors start turning again every few seconds.

Can anyone help please?

Hi, Hunnam

If your DRO's aren't moving, Then it must be some other program in the background on your computer.

Did you Re-Boot your computer after installing Mach3 ?

Run the Driver Test, It's in C:\mach3\  folder.

Re-Install Mach3.

May need to referr to the Optimization Doc. hear  http://www.machsupport.com/optimisation%20XP.txt

Thanks, Chip

Hunnam:

Check your electrical cables.  I had "twitchy," motors for a long time.  Ran fine, but when not running code the motors would jerk.  In addition the wireless mouse I use would occasionally not pickup all the moves.  Never could figure it out.  One day I was rearranging things on my bench and noticed a big difference in the mouse response.  My supply cords are long I had coiled them to prevent dangling.  When I moved the coiled electrical supply cords away from the wires running to my motors the twitching stopped.

Bob @ BobsShop - If a problem seems like it could be caused by some sort of electrical function - it usually is.
