Will there be a 2.85mm version of the Hemera? Looking at the new heatbreak, it's got a 4mm thread which has a minor diameter of 3.002mm (if it's 0.7mmm pitch) or 3.272mm (0.5mm pitch). That doesn't leave any 'meat' in the heatbreak to push a 2.85mm hole down the middle; the sidewalls would only be 0.076mm thick - sneeze within 5 feet of it and it would snap! A 2.85mm version would, at least, require a different heatbrake and heatsink. This doesn't seem to fit well with E3D's ecosystem compatibility Comments E3D?
Hi Ruffle, We currently have no plans for a 2.85mm Hemera, its been almost universally accepted within the industry that 1.75mm is the objectively better filament diameter. Manufacturers that still use 2.85mm at this point in time are seemingly using the "non standard" as a way to effectively chip filament.
Its a pitty for me too. I stashed too much filament in 2.85mm. (My printer manufacturer had 3mm default.) I should have known this earlier. E3D always seems to start with 1.75mm and sometimes increases the portfolio to 2.85mm. But I already checked the datasheets and the slim M4 heatbreak does not seem to be compatible to be changed in future. Even if you would use a drill and cut threads in: Then the heatbreak is a problem. So whatever Filament l have left will be pushed through titan aeros. My personal feeling is: Dropping 2.85mm standard after all seems to resolve double developement and should lead to a better market after all.
