Shakedown Checklist

Prior to Turn-On

1. Do not plug the 3D printer into a wall outlet yet. Verify power plug to power supply is Line, Neutral, Ground - in that order. The ground is the green wire. Either polarity of the L and N wires will work, but the correct convention is white wire for Line and black wire for Neutral.
2. Plug in RAMPS green plug to - + - + in that order from the left of green plug looking at the control panel.
3. Verify that the LCD is plugged in correctly - plug 1 and 2 as labeled
4. Plug in USB cable to computer
5. When USB cable is plugged in, LCD lights up saying OSE D3D Printer ready. This assumes the firmware is already on the controller board.
6. Check the thermistor on the extruder. Plugging the white thermistor wire into the control board should produce the temperature reading on the LCD. Unplugged shows zero temperature, and shorted shows max temperature. Temperature should be around room temperature for both the extruder and the heated bed, in C.
7. Check that all the adjustment screws on the RAMPS board are facing down, otherwise turning power on can burn them out.

• Plug in

• Verify axis motion
• Verify all printing parameters - G_Codes#Status_Codes
• Make sure print profile (.ini file) is correct)
