Title: reference all home - probblem adding to stock button code
Post by: shorton on August 08, 2015, 09:26:03 PM

 I'm a Mach3 beginner.  I have a small CNC router I built a year or so ago.  My machine is a fixed gantry and my home switches are located in such a way that my table homes to the rear of the machine (min Y) when I execute reference all home.  After that, I almost always move the table back to the front of the machine (max Y) to deal with work pieces.  That works fine but I wanted to automate that move back to the front after I reference home.

I went to Operator, Edit Button Script and changed the "reference all home" code as follows:

Code: [Select]

DoButton( 24 )
DoButton( 23 )
DoButton( 22 )
DoButton( 25 )

DoOEMButton(133)
DoOEMButton(134)
DoOEMButton(135)

Code"G0 Y14.7"

It sort of works.  But it executes the move to 14.7 first, then does the reference all home.  Is there a way I can get that command to happen after the reference all home?

Thanks,
Scott

I figured it out.  This seems to work:

Code: [Select]

DoButton( 24 )
DoButton( 23 )
DoButton( 22 )
DoButton( 25 )

While (IsMoving())
Wend

code "g53 x1 y14.7"

It should be:

While IsMoving()
Wend

You should also have one after

code "g53 x1 y14.7"

Like this:

Code: [Select]

DoButton( 24 )
DoButton( 23 )
DoButton( 22 )
DoButton( 25 )

While IsMoving()
Wend

code "g53 x1 y14.7"

While IsMoving()
Wend

Thanks Gerry.  I'll correct it.  Much appreciated.

While I'm at it, what do these do?  They have no apparent effect, although I expect they are there for a reason and doing something :)

DoOEMButton(133)
DoOEMButton(134)
DoOEMButton(135)

They zero encoder DRO's I think.
Most people don't need them.
