Mike,,,spend as much time as possible researching,,,I've worked at shops where purchasing a cnc and panel saw caused more damage than good,,,they are very good tools but make sure you have the work,,,if you have no cnc experience,,take 6-8 months minimum,,call all the manufacturers,,,(biesse,thermwood,stiles,komo,anderson,onsrud,scmi,masterhood,nort
hwood)and ask to visit customers to have those machines,and get their feedback,,the last person to take advise from is salesman. after you decide what machine you want and you are certain it will make you money,,next research on software,,auto cad is must must have,,then alphacam(to generate the tool path) and cabinet vision for cabinet boxes) and a post processor(these software packages worked best for me and the shops i worked for),,,now that the software and machine are complete,,you need a nice air compressor, 100lbs ps (primarily for tool changes) and heavy electric,,,(most machines today have a built in transformer) but your building should have no less than 208/230v minimum. and a 10hp dust collector,,,(surfacing your mdf spoil without a dust collector may kill you) as this one crazy customer i woked for,,
DO NOT BUY A USED MACHINE UNLESS U SEE IT UNDER POWER AND IT HONES PROPERLY,,,,,good luck,,,,
