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 subchapter guides you to mechanically calibrate 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 are from the same version. 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 itself the parts
of the hot-end are 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 the steps 1 to 4 where the difference lies and you are
able to slightly adjust the length by applying more torque to the parts of the hot-end.
