3.2 Extra calibration for dual extrusion printers

NOTE:
his step is only intended for people who bought a dual head DIY kit. Otherwise skip to next
T
subchapter.
This section guides you through the process of mechanically calibrating your DUAL head setup. The following
checks make sure the hot-ends will have the same height with respect to the just-leveled heated bed.
1. Make sure the heated bed is leveled correctly.
2. Make sure the hot-ends have the same revision. Otherwise, mechanical adjustment might be required.
3. Make sure the bottom bolts are gently fastened with an equal amount of torque.
4. Is the height of both hot-ends equal? If not, do the following checks to see what could be the cause.
If the hot-end tips have a different height, it could be that during assembly of the hot-ends the parts were
not fastened with an equal amount of torque, or that the tolerances are out of spec with one of the two
hot-ends. Please check with steps 1 to 4 to see where the difference lies. If necessary, you can slightly
adjust the length by applying more torque to the parts of one of the hot-ends.
