Nope. If it works, just keep using it.- do I need to upgrade the machine if everything is working & it cuts wood?
The spindle won't make any difference at all. You can cut aluminum or brass, but no ferrous metals. And thin metals are not easy to cut.- with the current configuration can this cut soft, thin metals or do I need a spindle to do that?
How much are they asking for the machine?
Call AVID and ask them. It should.
- with the current configuration will it work with the 3hp P&P spindle / VFD System that AvidCNC has?
