This enables the drivetrain to fit within the frame of a Nema 17 stepper motor - more on compactness in the next section. (Look familiar? You may remember this self-cleaning tooth profile in the Titan extruder.) Hemera drive gear closeup - individually CNC cut teethĪs a result of opting for an all-metal hardened stainless steel drivetrain, we were able to reduce the size of the gears. Sharp teeth - with a round bottomed profile - provide excellent grip and strongly resist filament debris wedging into the drive gear and in almost all cases it’s self-cleaning as any debris simply falls off the teeth. All the gears are hardened stainless steel. The secondary gear shaft is on a moveable, sprung idler which allows the user to adjust filament tension. We are able to push filament with up to 10kg of force. Dual Drive - Push Harderįor E3D Hemera, we opted for a dual-drive arrangement which provides a huge boost in grip over single drive systems. Thanks in advance for your understanding. If you see any instances of the old name hanging around please do let us know too.
Please do excuse us if some of the content is slightly less polished than usual, it's been a long hard night. Therefore we've had to undergo a rapid unscheduled rebranding, and have settled on Hemera, a somewhat less fashionable Greek god, yet still in keeping with our other mythological names, and our first female one too. Unfortunately, we don't have the time or resources to resolve this through a long legal process and we just want to get on with making incredible extrusion systems. They objected to us naming our product after a Greek god from the Mycenaean era, as they feel that name belongs to them. Unfortunately, less than 24 hours before launch, we received a legal challenge from a company much larger than us, and with significantly more legal resources. You're probably wondering why at the last minute everything that you were expecting to be called 'Hermes' is now called 'Hemera'.
