General Mach Discussion / Re: Cycle timer

I'm confused...mine definitely resets after a tool change and cycle start is pressed.

General Mach Discussion / Cycle timer

On the program-run screen under the tool information area there is a timer that shows elapsed time. This timer resets to zero each time a tool is changed and cycle start is pressed. I would like the timer to keep running until the end of the program to record an elapsed cycle time for the entire program.  Is this possible?  Thanks.

Hood, Thank you very much. I think telling Mach3 to ignore tool changes has solved the problem.  It has run lots of  parts now without a hitch. Thanks again.

Well I just made the changes you suggested and ran 5 parts without any problem.  That just might be the solution.

I am curious what is going on here behind the scenes.  Is the M6 command contributing to the random moves?

Another interesting thing happens with your code, After a tool change the spindle now starts at the previous speed and noticeably changes to the new tool speed. I don't remember this happening before.

Hood,

I watched it closely this time.  The tool position was exactly where the toolpath display said it should be.

This is what happened today:

The first two parts ran flawlessly

The third part started off ok but then after a tool change mach3 executed the z move first, milling down into the part in the wrong location and then plowed through it to the proper x and y coordinate where it proceeded to mill the pocket

This is just one example sometimes the random moves can be far from their proper position.

Thank you Hood. Here is my XML file.

Is it when running a program, or your spindle is on? Maybe noise?

It happens only when running a program and right after a tool change. Yes the spindle is running and is under mach3 control.  It happens with programs that usually run correctly.

I am getting random axis moves in the wrong direction.
It can occur on any axis and seems to happen at random times.
Usually everything works as it should but a couple times a day it will go the wrong way in the middle of a program that usually runs fine.
My setup is: Mach3, windows XP, CNC4PC C11 breakout board, automation technology drives

Thanks for any suggestions
