  2. The config.g file has approximate numbers for the tool offsets, set by a G10 command towards the end of the file.
    • The config.g file has approximate numbers for the tool offsets, set by a G10 command towards the end of the file.

    • This guide will fine tune those offsets so you can print multi materials.

  3. Set the Active temperatures for the Tools and Bed for the material(s) you are using. In this case I am using PLA.
    • Set the Active temperatures for the Tools and Bed for the material(s) you are using. In this case I am using PLA.

    • Remember to Home the machine and Mesh Compensate the bed.

    • When ready run ToolChanger - Calibration.gcode.

    • We are using T0 as the datum for calibrating the tools. T0 will not have any alterations to its G10 offsets.

  4. Each tool will print matching X & Y Vernier scales. The major divisions are 100 microns and the minor are 50 microns. If the scale for the X-Axis is shifted left, then you add the adjustment to the current offset.

    • The major divisions are 100 microns and the minor are 50 microns.

    • If the scale for the X-Axis is shifted left, then you add the adjustment to the current offset.

    • If the scale for the Y-Axis is shifted towards the front of the machine then the adjustment is added to the current offset.

    • There are + & - symbols to help make the process easier to understand.

  5. Make a note of the offsets for each tool. Make the adjustments in config.g.
    • Make a note of the offsets for each tool.

    • Save the file.

  6. Carefully list up a pair of verniers. Using calipers measure the T0 print. Measure the T<1,2,3> print.

    • Make a note of the difference for each tool.

    • Adjust the number in config.g

    • Note that the values must be reversed. For example T1 adjustment is -0.12. The value must be added (changes for - to +) to the current offset.

    • Save the config.g file and reboot the machine.

  8. Home the machine after the reboot.
    • Home the machine after the reboot.

    • Reprint the calibration file and check that the adjustments have worked.

  9. When you are happy with the calibration go ahead and run a multi material print. The included kraken.gcode file should run just great. Download the Kraken.

This calibration file has been pre-sliced using settings for the Titan/Bowden setups. As such it could be a problem printing it using other setups. Is there an unsliced stl available???

Right?! It’s generally considered bad form to run someone else’s gcode, anyway. Why would they not upload the stl?
