SE300 v1.4 Hotend Variations

SE300:  Probing since 2016!

The SE300 hotend is the same hotend used on all BOSSdelta, Artemis, RostockMAX v3.2 and RostockMAX v4 models.  No soldering required. The pcb is designed and manufactured in-house at SeeMeCNC! 

The on-board micro controller and probing strain gauge circuit are built-in and based on the Duet Smart Effector circuit. Our 4 layer pcb contains two inner layers with squiggly sensor traces used to detect strain when probing. Each board is programmed and tested for functionality. To compare probing, the strain gage probe is three times more sensitive than the HE280 accelerometer probe. More accurate probing, more reliable probing. A bright blue LED clearly indicates probe sensing. 

The triple blower design provides exceptional part cooling right where it's needed!  Make incredible no-support bridges and improve print quality while reducing clean up post print processing. 

Let's not forget about the bones!  The industrial grade glass filled nylon frame is heavy duty!  The injection molds are made in-house. Then we also injection mold the parts in-house too!
