I don't have or use qwick code so I'll try and answer best I can.
Dpthcut? is this the total amount to be cut?( I would suspect this is per pass, not total. Try per pass and see. Try small amount first, to be safe)
Xdist? is this incremental from 0 work offset or absolute position to mill too?( it want to know if you want it to mill to this position, absolute or if it is an incremental amount from your work zero)
YDist? same question
Feed rate? For some reason this appears to default to something other then I enter. Maybe just reading it wrong in the code.
( I believe you need to push "write" after you enter your feed rate value or it defaults back to the default value)
FeedZ?( this is your feed rate in z to plunge into the material, normally 1/2 your regular feed rate)
I'm sorry I'm not more help, but as I said I don't have this turned on on any of my machines. It was an option that we don't use or have. As always call if Ican help.
