  1. Ensure the printer is turned off and not plugged in. While moving with the extruder, the X-axis motor works as a generator. You will create a small amount of electricity and the LCD might flicker. Move with the extruder reasonably slowly and in the future always use the printer's controls. Move the extruder manually all the way to the left.

    • Move the extruder manually all the way to the left.

    • By rotating BOTH threaded rods at the same time on the Z-axis move the nozzle until you reach the heatbed. Try rotating both the rods equally!

    • Check again from a different angle the nozzle is touching slightly the heatbed. Don't bend the heatbed!

  2. Move the extruder carefully all the way to the right. Make sure that the nozzle is not scratching the print surface during the movement! If it does, rise the right side of the X axis by rotating the right Z motor slightly clockwise.

    • If an adjustment is needed, you can lower the nozzle height by rotating the right Z motor counter-clockwise.

  3. Move the extruder to the center of the X-axis. Locate the spare parts package, take the longest zip tie and place it under the P.I.N.D.A. sensor. Use the middle part of the zip tie, not the tip. Release two screws holding the P.I.N.D.A. sensor and gently press it against the zip tie.

    • Tighten screws on the P.I.N.D.A. holder again.

    • !!! DO NOT use glue to fix P.I.N.D.A. probe in the new type of holder with M3 screw(s), you won't be able to release them again !!!

    • A correct height of the P.I.N.D.A. sensor compared to the nozzle should be similar to the last picture.

    • Note the video includes previous version of the MK2 with a slightly different look, however the principles of the calibration and printing are the same.

    • Read the chapters 3.2 Disclaimer and 3.3 Safety instructions

    • Read the chapter 6.3 Setup before printing.

    • Download and install the drivers - chapter 9 Printer drivers. Don't forget we have ready to print settings for Slic3r, Cura and Simplify3D.

    • Calibrate the printer by following the chapter 6.3.1 Calibration flow. Please follow the steps exactly, otherwise you can permanently damage the print surface!

  6. Read the chapter 7 Printing of 3D Printing Handbook.
