General Mach Discussion / Good spindle motor and controller for Mach 3

« on: March 08, 2011, 04:52:02 PM »

Hi, I'm looking for a good spindle motor and controller for my mill that will work well with Mach3.
The Mill is a Novakon NM-200, (nightmare) Lastest problem is the "so called" 3HP Brushless DC spindle motor quit and I have been waiting over a week for a replacement under warranty but it still hasn't left China yet.
So if someone could recommend a good, around 3HP motor and VFD or controller that works well with Mach I would really apprieciate it.
Thanks.

General Mach Discussion / 4th axis question

« on: December 15, 2010, 09:57:29 PM »

Good day,
I'm having an issue with my 4th axis, (running Mach3)
I can't get the rotation feed to speed up as fast as I want. I have radius correct turned on but the only difference it seems to make is, if I set radius to 0.0001 to use Z as radius, the feeds speed up as the radius increases (which seems backwards) Setting it at any radius other then 0.0001, just slows it down all the time.
The part is an eliptical lobe shape, and the feeds speed up as the cutter raises and lowers at the lobe part, but slows back down for the other 180 degs, the constant radius circular arc part.
I can jog the rotary table fast enough to use it as a lathe, but when cutting it's slow.
any idea's?
Thanks,
Ray
