CNC Wood Router using NEMA 17 steppers

Size 17 stepper motors on a table top router with an AXI Outrigger motor for the spindle drive. All running with a Xylotex 3 axis drive board. The motor is powered by a PC power supply at 6 amps and 12 volts. The Xylotex drives are powered by a toroidal transformer at 28 volts. The X axis lacked a bit of power as it was so I geared it down about 3:1 and now it works a whole lot better and I have isolated the spindle motor so it now uses a toothed belt to drive the spindle just a little bit faster, about 10K revs. Still 10K revs too low for a 1/8 milling cutter.

I use a servo tester to run it. You have to start it by hand though because they start in Mid Band (or something like that)

Using a AXI for a spindle motor is a great idea, I have a few outrunners laying around. What are you using for a controller/ESC for the motor? thx HHO95667
