Stage 02: Dual Switching Hotend Upgrades

Replace the 3D printed probe mount with the aluminium one.

Start by pushing the probe through the new mount and then secure it in place.

M2.5 x 6mm bolt

Replace the steel heatbreaks with the new Copper/Titanium ones.

You may need to heat the heat block to free the old heatbreak, if this is the case you can use either a lighter or wait until you have completed the build and heat the hotend via a gcode command.

Replace the thermistor with the new one.

Connect them to the control board.

The servo arm design has been updated to incorporate the small arm included with the servo.

The 3D printed part of the arm can be found here, we recommend printing it in ABS.

If the injection moulded arm does not fit, there is a large version of the arm that can be found here.

Drop the injection moulded arm that comes with the servo into the 3D printed arm.

Attach it to the servo shaft as shown with an M2.5 x 6mm bolt.

Fix to the tool carriage the 3d printed cable relief bracket.

M3 x 10

Use cable ties to secure the cable loom to the bracket.

Move the print head to the near right of the print area.

Use cable ties to secure the loom to the side panel.
