Upgrade your v3 for even more amazing prints.  Scroll to bottom for notes regarding upgrading your RostockMAX v3. 


The SE300 hotend is the same hotend used on our Artemis 300 and RostockMAX v3.2. No soldering required for either kit or assembled hotends. 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. The 4 layer pcb contains two inner layers with squiggly sensor traces used to detect strain when probing. This arrangement is surprisingly sensitive. Each board is programmed and tested for functionality. To compare probing, the strain gage probe is three times more sensitive than the HE280 acceleromter probe. More accurate probing, more reliable probing. A bright blue LED clearly indicates probe sensing. 

The probing arrangement meets PartDaddy's requirement of using the nozzle itself for print surface contact. Like the HE280, this simplify's probing and nozzle changing for a better experience. Let's say you wanted to experiment with the bed or nozzle or other aspect of the hotend, you won't likely need to modify configuration settings for the probe to work. 

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 at SeeMeCNC of PartDaddy's design. Then we injection mold the parts in-house too!
