Mach4 General Discussion / Mach 4 Goto Work Zero
« on: October 18, 2018, 06:03:31 PM »
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
