Good evening
I would like some help to modify this "ref all home" macro I use:

Speak ("  zero   macchina") 'Avviso Vocale
   Message "************   ZERO MACCHINA ************"
   Sleep (1000) ' pausa di 1 secondi
   
   DoButton(24)
   DoButton(23)
   DoButton(22)
   'DoButton(25)
   While IsMoving()
   Sleep(100)
   Wend
   SetParam("XRefPer", GetParam("XRefPer")/15)
   SetParam("YRefPer", GetParam("YRefPer")/15)
   SetParam("ZRefPer", GetParam("ZRefPer")/15)
   'SetParam("ARefPer", GetParam("ARefPer")/15)
   DoButton(24)
   DoButton(23)
   DoButton(22)
   'DoButton(25)
   While IsMoving()
   Sleep(100)
   Wend
   SetParam("XRefPer", GetParam("XRefPer")*15)
   SetParam("YRefPer", GetParam("YRefPer")*15)
   SetParam("ZRefPer", GetParam("ZRefPer")*15)
   'SetParam("ARefPer", GetParam("ARefPer")*15)
   Speak ("zero macchina completato") 'Avviso Vocale

the change I would like to make is the following:
1) the "Z" rises up to the origin
2) the "X and Y" simultaneously up to the origin
I state that I do not understand VB, is it possible to modify it? Is there anyone who can help me?
thank you
