Installing a Hotend
- Thread the Hotend's Bowden tube through the Hotend holder.
- Ensure the Hotend is pushed up all the way into the Hotend holder.
- While pushing the Hotend upwards, tighten the Hotend’s holder screw.
- Plug the Hotend cables back into the connectors.
- Put the front print head cover back on the print head, and check that the Hotend wires do not show below the bottom edge of the cover
- Preheat the Hotend to a 205 c temperature using the manual controls (Setup > Manual Controls > Controls).
- When the Hotend has reached 205 c, grab the heat block using pliers and use a wrench to tighten the nozzle to make sure there is no gap between the PTFE Bowden tube and the Nozzle/heatbreak.
- Put on the heat block sock.
- Check calibration.
