Either software packages you mentioned can interface with DeskCNC. Your software supplier should give you a post processor free of charge (if they have quality service). I have a customer using visual mill with deskcnc just fine, he sent a sample program to the visual mill distributor and had a post within 24hrs.
Good choice using deskcnc, great product!
