1. Send command “M503” (Sending G-code)
   
   • (USB only for most V2's. Some early V2's and V1's should be able to receive response via WiFi also.)
2. Look for:
   • “Steps per unit:”
   • V1: “M92 X93.00 Y93.00 Z1097.50 E97.00”
   • V2: “M92 X46.50 Y46.50 Z548.75 E48.50”
     • or
   • V2: “M92 X93.00 Y93.00 Z1097.50 E97.00”

“E97.00” in the V1 example above are the E steps per mm
