Title: home button on auto screen?
Post by: Fred_evans on December 23, 2011, 02:35:14 AM

Hello There ,
I am still finding my way with mach3 turn.

How do I get the tool to move to the home position when I am on the
"auto" screen?
at the moment i always have to go back to the manual screen to home the tool

Regards
fred

Only way is to add a button yourself with a screen designer (Screen4 ro MachScreen)

I am not a fan of the standard lathe screen it js very awkward to use in my opinion.

You could MDI G53 X0 Z0 as a substitute for a button.

G53 Move in ABS Coordinates
Absolute machine coordinates:G53 - move in" For linear motion to a point expressed in absolute coordinates, program G1 G53 X~ Y~ Z~ A~ B~ C~ (or similarly with G0 instead of G1), where all the axis words are optional, except that at least one must be used. The G0 or G1 is optional if it is in the current motion mode. G53 is not modal and must be programmed on each line on which it is intended to be active. This will produce co-ordinated linear motion to the programmed point. If G1 is active, the speed of motion is the current feed rate (or slower if the machine will not go that fast). If G0 is active, the speed of motion is the current traverse rate (or slower if the machine will not go that fast).

.....to be clearer, G53 will only work if the machine is already referenced.
Youd need the button to actually reference the machine.
Your question has 2 aspects.

Hello Hood--and Overloaded I will try machscreen later- still to much of a novice for this


Hello Russ- this looks like it may be what i am looking for--
question "machine must be referenced" does this mean that i have already
selected a" set home x" and a "set home Z" on the manual screen?

or if it means something else then please elaborate??
thanks

Yes, referenced and homed mean the same, sorry for the confusion.
If it were not homed first, then using G53, the axis might hit a limit as it will not necessarily know where the extents of the machine axis's are.
