So I am picking up more jobs for my Fine Line Automation 4x4 Saturn2 cnc router, I am thinking of a spindle, air cooled as I do not want to mess with another pump and cooling system. My last job ran for 7 hours, the air cooled router I have now seemed to be ok but....
Automation Technologies has a nice assortment of the 2.2 and 3 Kw ones, round 80 mm to fit my existing mount. Thinking also of a Hitachi VFD thinking the Chinese ones may have issues. I have a 14 pin cable ordered from CNC Router parts online to connect to my prewired control box and of course I will need to wire the other end to the VFD terminals.
Suggestions?
