Home switches

Hi there, How can I get the axis to step off the home switches so they are clear by about 5mm ?

AFIK there is no setting for this, if the axis is not stepping back or only just stepping back it is likely switch bounce - try adding some de-bounce and try again, might need deifferent switches.

If I understand you correctly you want to ref an axis which goes to the limit switch and then backs off until the switch is inactive and then proceed another 5mm.  If that is correct then choose operater->edit button script and then click on the ref all home button. 

DoButton( 24 )
DoButton( 23 )
DoButton( 22 )
DoButton( 25 ) c
Depending on what axis you want to move off from change to:

DoButton( 24 ) ; ref Z
Code("G1 Z5")
DoButton( 23 ) ; ref Y
code("G1 Y5")
DoButton( 22 ) ; ref X
code("G1 X5")
DoButton( 25 ) ; ref A
