Mach4 General Discussion / Re: Mach 4 Goto Work Zero

Craig,

Thank you for your help.  I edited a copy of the screen set.  Long story, but it didn't work at first, but I finally figured out why and fixed it.  Also, my machine wouldn't move on G00 Y0 X0 Z0 in the MDI screen either.  I discovered when I used the G00 and G01 commands, the machine was moving incrementally rather than moving to absolute positions.  After much frustration, watching some Mach 4 videos and reading a few things about G-codes, I tried using G90 in MDI.  Then the "Go To Work Zero" button worked.

I had previously run one off the test patterns- Arc Test- and it went into a never ending loop.  So I stopped it manually.  Apparently I stopped it after a G91 command and so I was stuck in G91 mode the whole time.

Anyway, it's working now after running G90 in MDI.

Thanks,
Bruce

Craig,
I re-homed my machine, then moved X,Y,Z and zeroed each individually for work zero.  Then I moved each axis away from the work zero coordinate.  Next I triec “Go To Work Zero” button.  It didn’t move, and the status bar reads “Axis 3 commanded while Disabled' just as you suspected.

Ok what do I need to do? I was hoping not to do any edits, but I guess I’ll have to do that.

Thanks,
Bruce

Craig,
That is the button I’ve been trying to use.  I won’t be able to check the status bar until Sunday.  When I do, I’ll write back.  I appreciate your help.

Mach4 General Discussion / Mach 4 Goto Work Zero

I have Mach 4 Hobby with the PDMX plugin on a Joe's EVO 4X4 that built.  I am doing simple test runs without a router bit to make sure things are working.  I'm using my X&Y Negative end limit switches and Z Positive (top) limit switch as the home switches.  I enabled soft limits and set the Min & Max Values in the appropriate table.  I have successfully homed using Ref All Axes.  Then I moved X&Y 10 inches in the postive direction and the Z-axis down 4 inches and zeroed each axis.  Next I loaded one of the sample G-codes and ran it ("Arc Test" I think), and hit Regen Tool Path.  First of all, the g-code program won't run when I have the Soft Limit button turned ON (green light).  When I turned it off, I could run the program.  I don't understand that.

I let the pattern run, then I stopped it after a couple of complete loops (this pattern will run in a never ending continuous loop for some reason, but other patterns I've tried don't).  Next I hit "GoTo Work Zero" assuming it would go back to the starting coordinates.  But the machine does nothing.  The only way I could get it to go back to my starting point is to type G1Y0X0Z0 in the MDI screen and run that.  I have checked the G54 coordinates in the offset tab and it shows coordinates 10,10,-4 as I believe they should be.

This is my first experience with this.  I would prefer to not to start copying and pasting code to change the screens until I get more proficient at Mach 4.  Does anyone have a solution that don't involve customizing screens at this point?  This is based on my assumption that GoTo Work Zero is supposed to do what I think it should do.  Maybe I don't understand its intended function after all.

Also, what is the purpose of De Ref All Axes?

Thanks
