I'm searching for a new CNC machine and I'm having trouble getting started finding one because I have relatively few hard requirements. The main points I'm working with are that I need to be able to mill 5mm polycarbonate sheets at a low to medium rate. I'm worried that polycarbonate won't dissipate the heat well and will require a loud cooling system. The other point is that the system needs to be relatively quiet, ideally someone should be able to talk on the phone about 15-20 feet from the machine without distraction. Is that possible within a budget of 10-15k? TIA!
