Post your homing code.

RefCombination(7)

While IsMoving()
Wend

SetParam("XRefPer", GetParam("XRefPer")/10)
SetParam("YRefPer", GetParam("YRefPer")/10)
SetParam("ZRefPer", GetParam("ZRefPer")/10)

RefCombination(7)

While IsMoving()
Wend

SetParam("XRefPer", GetParam("XRefPer")*10)
SetParam("YRefPer", GetParam("YRefPer")*10)
SetParam("ZRefPer", GetParam("ZRefPer")*10)

Are you seeing a limit switch error?
Set a debounce of about 5000 and see if it works. Sounds like noise is triggering the switches while backing off.

Debounce in Mach settings or in the homing code?  Can I put a pause command after the 1st Wend in the homing code I posted?

General Config.

try this code, had a simular thing couple of weeks ago:



RefCombination(7)

Sleep(300)
While ((GetOemLed(807) = true) Or (GetOemLed(808) = true) Or (GetOemLed(809) = true))
   Sleep(50)
Wend

SetParam("XRefPer", GetParam("XRefPer")/10)
SetParam("YRefPer", GetParam("YRefPer")/10)
SetParam("ZRefPer", GetParam("ZRefPer")/10)

RefCombination(7)

Sleep(300)
While ((GetOemLed(807) = true) Or (GetOemLed(808) = true) Or (GetOemLed(809) = true))
   Sleep(50)
Wend

SetParam("XRefPer", GetParam("XRefPer")*10)
SetParam("YRefPer", GetParam("YRefPer")*10)
SetParam("ZRefPer", GetParam("ZRefPer")*10)

It sort of worked. The parameters would get out of sync so on subsequent homing it would sometimes start off on the lower federate.  Instead of using getparam, I just typed in an actual value that suited my needs.   Thanks guys.
