Thick Paste Extruder file starting (with calibration)

Information on how to prepare a .gcode file is avaliable in the 'Thick Paste Extruder file preparation' article and the article 'Communication and File Delivery'  shows different ways how to transfer the file to the machines memory. 

After uploading the file to an internal card or inserting an external SD card with the prepared file:


  • Enter the 'New Job’ menu,

Note: If the user inserted the external SD card the screen should jump forward to the 'Choose File' section screen on the 'EXTERNAL’ directory.

Note: If there was no previously chosen file, after pressing on the 'New job' menu the screen will go directly to the 'Choose File' section.


  • Go to the 'Choose file’ section,

  • Files uploaded to the internal SD card are located in the 'INTERNAL’ tab, files uploaded to the SD card are located in the 'EXTERNAL’ tab,

Before starting the Thick Paste printing process the machine must be calibrated to the mounted material or the worktable surface. Skipping the calibration process may result in damaging the machine or the toolhead.

  • Go to the 'Calibrate' section,

  • Press 'Set',

Note: The movement in the X and Y axes will be disabled until they are homed. It is a safety procedure, to protect the machine against damage.

Note: The movement in the Z axis is avaliable all the time. Use it to move the toolhead above the surface height of the prepared material.

Note: The information on the Z axis height is stored in the motherboard internal memory. That is guided by the fact that this value is not easy to change manually by the user unlike the X and Y axes.


  • Press the 'Home X' and 'Home Y' buttons. Watch out for your toolhead not to hit the material on the worktable,

Note: Don't home the Z axis when there is material on the worktable. This might disarrange the Z axis motors. 


  • Go back to 'MOVE' menu,

  • Using provided arrow buttons, move the Thick Paste Extruder to the LOCAL starting position. More about what is local position in the 'Global and Local dimensions' article,

Note: In most cases the local starting position will be the material surface left, front corner.

Note: Toggle the distance button mceclip1.png for better control over the toolhead.


  • When the toolhead is in its local starting position, go to the 'SET' menu and set the local 0,0,0 coordinates by pressing the 'Set X = 0', 'Set Y = 0' and 'Set Z = 0' buttons,
