Last updated on March 23, 2020 11:43

Insert the heater cartridge and temperature sensor into the Olsson block. It’s important that they go all the way in. Both sensor and heater should be visible when looking through the small holes placed next to the set screw in the block
Make sure to point the open side of the heater cartridge downwards to prevent filament from entering it
Screw the set screw into the Olsson block so that it fixes the PT100B sensor and the heater cartridge in place. Make sure that the set screw is properly aligned with the corresponding hole in the bottom aluminium plate of the print head before tightening
Make sure the sensor and heater are well secured by gently pulling the cables to see if they remain in place
