Additional Items Required
5A Remove screws
5B Lift cover
Depress the retaining tab on the connector housing and gently wiggle the connector free. Do not pull on the wires, only the connector housing.
The tool head is attached with three screws. The print surface can be damaged if the tool head is allowed to fall onto the print surface. With one hand, support the tool head while following removal steps below.
Using the 2.5mm hex key, unscrew the three M5 screws securing the tool head to the X-axis carriage. Remove the rear screw first, followed by the remaining top two screws.
Remove the tool head from the printer by moving the tool head away from the printer.
Note: In previous versions of our tool heads, the Esteps (Extruder Steps Per Unit) were listed along the back of the tool heads for the customer to update. For the new HS+ Tool Head however, the Esteps are now set up within the firmware, and no manual updates are required.
Press the tool head onto the X-axis carriage, aligning the cutouts on the back of the new tool head. Do not pinch any wires between the mount and the carriage.
Secure it to the X-axis carriage by loosely screwing in the top two screws. Leave the top two screws loose.
Loosely screw in the last screw through the rear of the X-axis carriage.
Tighten the top two screws.
Tighten the rear screw.
Connect the two connectors, making sure to fully seat the connectors until they lock.
Cover the connector with the connector cover and attach it to the X-axis carriage using the three M3 screws and the 2.5 mm hex key.
Channel the wires together going to down the vertical pathway on the cover mount, and try not to pinch any of the wires when securing the cover. Slide down carefully into place, and hold while screwing in.

Note: Always heat the hot end to extrusion temperature before attempting to remove filament. If switching between different material types, set the hot end to the approximate average extrusion temperature of the two materials.
Once the hot end has reached the extrusion temperature of 205, remove the test filament used during factory calibration by entering 5 for the Extrusion amount in Cura LE. Click the Extrude button. Change the value to 60 and click the Retract button.
Once filament has retracted 60 mm, squeeze idler inwards, and pull the filament out. You may need to loosen the idler slightly by turning the silver idler wheel clockwise.
Tighten the idler by turning the silver idler wheel counter-clockwise if loosened.
Filament Loading Tip: Cutting the filament at an angle will help with inserting into the extruder.
Load the sample filament into the extruder. Squeeze the idler arm inward and insert the filament into the extruder filament guide.
Enter 60 in Extrusion amount and click the Extrude button.
