Many people have Emailed me asking for specific details about how my steppers are wired, and how my limit switches are set up. So, I am posting this information for all readers to refer to. Keep in mind that this is how I wired MY system. Someone else may have different motors with different wire colors, etc.
I suggest you go to the Xylotex website and click on the tab labeled "Data Sheets & App Notes". You will find a lot of detailed information for the stepper driver board and power supply requirements. Here is a link to the 3-axis driver board that I used:
http://www.xylotex.com/3axBoard.htm Here are some wiring details from my own personal notes. It is how I wired my engraver for the motors and limit switches....
Motor wire colors (These are the original steppers on my New Hermes engraver):
Note: where two colors are shown, the color to the left of the slash is the main solid color, and the color(s) to the
right of the slash is the colored stripe(s)
X axis: A=white/orange A#=white/yellow B=white/grey B#=white/black
Y axis: A=brown A#=orange B=white/blue B#=white/red
Z axis: A=blue A#=white/red/black B=red B#=white/red
Limit/Home switch inputs to Xylotex board digital input terminals:
Note: Due to the limited number of switches on the engraver, some of the digital inputs are used for multiple functions.
+X = pin 11 -X = pin 10 X Home = pin 10
+Y = pin 11 -Y = pin 12 Y Home = pin 12
Z = No limit switches. Z home = pin 13
Spindle ON/OFF signal from Xylotex board to solid-state relay:
Output #1 = pin 14. CNC commands: M03 = Spindle ON, M05 = Spindle OFF
I used a 10 Amp solid-state relay with a 10 to 30 VDC input for turning the Spindle on and off. It's overkill, but that happens
to be one that I had in my spare parts box at the time. I don't recall what the motor is rated at, but I doubt if it draws more than a couple of amps at 120 VAC, and so you could easily use an SSR rated at 5 Amps if that's what you happen to have.
