MAKE = Dedicated home button?
« on: February 01, 2012, 09:31:43 PM »
I am thinking of making a dedicated home button or changing the REF ALL HOME button, so when its clicked it goes back to the actual corner of the machine 0,0,0,  NOT where it was moved to and zero'd out, so that when i am finished working i can hit the button and its parks back in the corner, at the moment i just close mach 3 and open it again and click GO TO ZERO, so how would you code it? or has anyone already done this
Thanks
Chris

The Ref All button should already do that?

My screen has a Park position with DRO's for the location and a button to send it there. Since it's in an M code, I also add the Mcode to all my gcode so the machine always goes to the park position after cutting.

The ref all home doesnt move it back into the very corner, if i move the machine into the middle and hit REF ALL HOME it sets that as my Home and my soft limits are no way of the table and i could picture my machine heading for a crash.

I had a look at your screenset and it looks nice, i will deffinatly purchase in the near future, i cant seem to find that PARK button on your screenset in the pictures
Thanks

You don't have any home switches, do you? You need them to do what you want, as that's the only way Mach3 can really know where the corner is.

Home switches are required with my screen for the same reason. Some of the functions (like the Park position) require that Mach3 has a 100% repeatable home position.

The Park button is the "P" in the toolbar. :)

You evidently do not have HOME switches installed/enabled.
If not, you can move the axis's to where you want home to be, then hit ref all.
Then, in a button, put Code "G53G0 z0x0y0"
