    • If you are wanting to counter bore the screws make sure the distance from the back of the mount and the counter bore shoulder is 5mm when using the supplied M3 x 8mm screws.

    • Using screws that are too short won't damage anything, it just won't be able to fasten the screw into the square nut.

    • When attaching part cooling fans, bed levelling sensors or mounting from the side with the fan exhaust, be mindful not to restrict airflow.

    • Blocking the heatsink exhaust will reduce airflow which can lead to heat creep and jamming of the extruder.
