Title: Go To Z but ignore A
Post by: deejayspinz on February 11, 2013, 04:04:44 PM

Hey everyone,

I modded my router to double as a 3D printer.  I'm using Mach3 and often have prints that fail and I have to restart.  The extruder is on the A axis and as it runs, it builds up distance in the DRO.  When I want to go back to Z (0 on X,Y,Z),  it also reverses the extruder gear to try to bring it back to 0 as well.  Is there any way to disable the A axis as being part of the Go To Z routine?  Or alternatively auto 0 it whenever I stop Mach?  I can't seem to find a setting for it, but then again, I'm not sure what I am looking for.

Thx

Best idea would be to guse a screen editor and change the Go To Z button into a VB button and then when back in Mach go to Operator menu then Edit Button Script. You can then enter some VB to make X Y Z go to zero and A will not move.

I can help with the code if you are unsure. I would need to know do you require the Z to rise before X and Y  then go back down to zero once they are at zero.

Thx for the offer. I was hoping for an easy fix, such as a configuration setting that could be changed.  Is this the only way to do this?

Go To Zero is what it says, sends all active axis to zero so no way to do it other than a custom button or MDI or you could probably inhibit the A before you press the standard button. Easiest would be to make the custom button, only takes a few seconds to do.
