I've sold my PM932 CNC conversion and am now in the market for another mill. A Novakon Torus Pro (I like the 15" of Y travel) is on my list as is a Tormach 1100M and a used Haas Mini Mill. After reading through this thread I'm concerned about post sale support. It seems a few of the posters here have had trouble in that area. I plan on calling them this coming week but wanted to get your opinions before doing so.
I've also read that Novakon may not be offering the stepper version anymore. Is this true? According to their website both options are still available. I'm also confused about the style of power draw bar they are selling. Is it an air operated cylinder type or a torque drive type. The website isn't clear on this.
Has anyone modified their mill for higher spindle rpm? I'm thinking a pulley change or a VFD parameter change will do it. Your thoughts?
Thanks
