General Mach Discussion / Re: Absolute Machine Coordinates Shifting??

« on: March 09, 2015, 03:44:41 PM »

You presume correctly. Maybe switches will ultimately be the best way to go. But for now I'll need to play with the software to figure out a solution.

And yes, both my persistent Offset and DRO are checked. As well as the "save offset" box. (Not that I know entirely what having them checked means haha)
But I assume that is why it asks to save my fixtures upon closing the program?

By external controller what do you mean? Doesn't Mach3 need to be installed on a external controller (i.e. a computer). I'm running it on Windows 7. Is that considered an external controller? And what else can Mach3 be installed on besides a computer?

Does anyone know how it sets the DRO's at startup? If I can figure that out I might be able to control it somehow.

Thanks!

Also, one side question: Does Mach3 support conditional statments? (e.g. If-Then statements with AND/OR logic devices)

General Mach Discussion / Absolute Machine Coordinates Shifting??

« on: March 09, 2015, 01:43:44 PM »

Hello,

I'm new to Mach3 so forgive me if I do not use the correct jargon. But here is my issue:

I've set the work coordinates G54 as (let's say) X=1, Y=1, Z=1 in absolute.
Now from what I'v figured out, each time I open Mach3 it will use G54 as a default work coordinate system.
So G54's zero should be at Machine Absolute's X=1, Y=1, Z=1.

But each time I close and open, G54's zero is now at something like Machine Absolute X=.5, Y=.5, Z=1.

Why might this shift be occuring? How does Mach3 come up with the Machine's Absolute Coordinate's upon boot up? Am I wrong to have expected it to be the same each time?

Thank you,

Corey

Hello,

Corey here. New to CNC the world. Recent graduate with a bachelors in mechanical engineering. I foresee needing some help troubleshooting with my new Romaxx cnc mini mill. Fun stuff!
I like to design, build and make things. Typically woodworking. But my brother and I built a small forge for melting aluminum last summer. Always fun to branch out!
