Prusa i3 Build Manual Step 4: Connect printer to PC Your printer does not need to be plugged into the wall at this point. Connect the USB cable to the port on the Arduino MEGA (the underside of the electronics) on the printer. Your computer should recognize the board and install the drivers automatically. If your computer does not see the Arduino board, you may have some wiring wrong. In that case, un-plug it and check all of your wiring, especially the end stops.

Prusa i3 Build Manual Step 11: Home Z axis Click on the Manual Control tab in Repetier Host and click on the Home Z button: This will bring the entire X carriage down so the hot end just about contacts the bed. Before you adjust the end stop for the Z axis, measure the distance between the bed and the nozzle, if you can it helps to make a cardboard spacer for the next step. © 2015 Reprap Guru, LLC | All Rights Reserved 21 WWW.REPRAPGURU.

Prusa i3 Build Manual Step 12: Level print bed Click “Disconnect” in the top left corner of Repetier Host and disconnect the printer from 110V power as well as the USB from the computer. Using the spacer you made in Step 11, manually move the print head to the left side of the printer. Use the spacer to adjust the bed height with the thumbscrews at each corner. Move the bed to the back and repeat the process for the front left of the bed.

Prusa i3 Build Manual Step 13: Set proper Z end stop height Connect the printer to 110v power and connect the USB cable to the computer. Open Repetier Host and connect to the printer. Go back to the “Manual Control” tab and home X, Y and Z. Grab a sheet of paper to set the Z height properly, bring the Z axis end stop down slightly and re-home the Z axis. We want the hot end nozzle to cause friction between the paper and the Glass on the heated bed.
