gMax 1.5+ Dual Extruder Alignment

To align a dual extruder you need to access the 4-40 screws which secure the dual extruder tool head to the X-axis plate. You must remove the LED light shroud to access these screws.

With the LED light shroud removed. Loosen the 4-40 screws circled in the picture below. You may find it easier to only loosen the top 2 screws.

Align the hotends on the Z-axis. Then tighten the screws down to secure the dual extruder in place. You may find it easier to bring the tips of hotends close to the bed. You can use the bed as a reference to help align the hotends.
