I am building a laser engraver. My frame is extruded aluminum, 18" long and 14"wide. My X rail is 2"X1" 14" long. What size stepper motors do I need for this project? I will need 3, two for the Y axis and 1 for the X axis. I have the Arduino and cnc controller.I was looking at the following:
holding torque:450mN.m
step angle: 1.8 degrees
phase: 2 phase
voltage: 3.75
current:1.5A
drive method:2-2 phase
resistance: 5.0 ohms

Thanks for any help.
