wire size to connect Frequency converter to 2.2 KW Router?

We use 16 AWG (American Wire Gauge) to connect the 2.2kW Spindle to the VFD (Variable Frequency Drive also called the inverter. Since there are three coils, the 2.2kW (2200 watt) spindle will draw 10 amps total or 3.33 amps per coil. 16 AWG will be more than enough capacity to handle 3.33 amps.

WHAT CAUSES RINGING IN YOUR EAR AND HOW CAN YOU STOP IT?

Tinnitus . Learn to love it. No really you should see a doctor. Make sure. White noise will help you sleep when it gets loud. Additional Information: I learned, too late, that if a sudden loud event causes tinnitus, see an audiologist IMMEDIATELY. They can do something about it if addressed within a day or so. Wear hearing protection...always. Loud noises trigger my tinnitus, and headphones and ear plugs (when out & about or at the movies, subway, etc) help tremendously. Mine are rated 33dB.

Need wiring diagram from mach3 USB breakout board to inverter.

I suppose you are trying to determine how to connect the VFD tothe relay on the breakout board. This is possible, however, not recommended as there is a more robust way to connect the VFD to mach3 or mach4 that allows that CNC machine control software to control the speed and other features of the VFD. Follow the instructions from this question (number 13383): https://buildyourcnc.com/FAQ/13383 To get to this answer, you can also ask this customer service "How can I connect my spindle's VFD to mach3?" Additional Information: If you still want to connect the VFD through the relay, I will clarify this instruction on this question tomorrow as I don't have the information in front of me at this moment. Thanks.

How would you recommend cutting glass with a GreenBull?

It depends on the type of cut you're trying to make and the type of glass. In general, straight cuts can be made by scoring the glass using a type of engraving bit, such as these: http://www.widgetworksunlimited.com/CNC_Specialty_Bits_s/33.htm. Complex curves and thicker glass is usually tackled with a diamond burr endmill and a specialized jig. Here is a nicely done you tube video giving an idea of how that works. https://www.youtube.com/watch?v=HyI111Tn0Cs

Every time the machine starts to cut a new pass it jumps +.033 inch on the x axis. Does anyone have any idea why it might do this?

If an axis is showing play when there is force against the axis (force in the opposite direction imposed on the bit when cutting material), the problem may be in the mechanical system. If the mechanical system is roller chain and sprocket, or rack and pinion, check the sprocket or pinion gear to confirm the tightness of the set screw. If the mechanical system is a lead screw, confirm that the coupling is secured well to the lead screw and the motor shaft. Additional Information: Additional Information: Additional Information:
