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.

Don’t get discouraged, this is the most challenging part of setting up any 3d printer, keep at it and you’ll get it!

Once you have the height set right at the X and Y home, use the controls in Repetier host to lift the Z axis 1mm

and move the X to the other side, don’t worry, it won’t go further than the firmware will allow (which is

200mm). Move the Z axis down 1mm and check the gap with paper on that side, use the thumb nut on the

underside of the bed to finely adjust the tension between the paper and the Glass on the bed. Repeat this for

the front left and right corners of the bed.
