![]() When attaching part cooling fans, bed levelling sensors or mounting from the side with the fan exhaust, be mindful not to restrict airflow.īlocking the heatsink exhaust will reduce airflow which can lead to heat creep and jamming of the extruder.ġ2. It looks like somebody did a similar attempt, but added the offset to the XMINPOS and mixed up the signs (it does hint to a 8 mm offset, so the creator probably also has a e3D Hemera extruder). The result of using M3 x 10mm screws with the same 5mm mount.ġ1. Image showing Hemera correctly secured to a 5mm mount with the supplied 8 mm M3 screws.ġ0. Using screws that are too short won't damage anything, it just won't be able to fasten the screw into the square nut.ĩ. If you are wanting to counterbore the screws make sure the distance from the back of the mount and the counterbore shoulder is 5mm when using the supplied M3 x 8mm screws. Using a mount thinner than 5mm with the supplied 8mm screws result in damaging the T-slots. Using screws longer than 8mm with a 5mm thick mount will result in damaging the T- slots. lining up the clearance hole in the mount with the threaded holes of the square nuts.Ĩ. Place the mount on the backside of Hemera. The backside is the side with the drive gear visible. I nsert x2 M3 square nuts into the empty T-slots on the backside of Hemera. Ideally, Hemera is fastened using x4 M3 screws, however, the minimum requirement is x2 screws diagonally positioned on the backside.ĥ. Screws should stick out from the mounting plate 3mm +/-0.25mmĤ. Shown here is a 5mm thick mounting plate using the supplied M3 x 8mm screws. Double-check before proceeding that you are using a suitable length screw for the mounting plate thickness used. This is how to correctly measure a screw.ģ. Bearing elements: 2x shielded 623 bearings (drive shaft), Igus bushing.2.Avoid using wire brushes on the hobb teeth or gears.Compressed air is a recommended method of dislodging filament debris from hobb teeth.Do not remove the grease from the drive gears. E3D Hemera Specification Summary Drive type: dual drive with adjustable tension idler Max printing temperature: 285C (upgradable to 500C) Mass: 388g (including V6 hotside) Max pushing force: 10kg Dependent on filament Flow rate (based on V6): 600mm/min Dependent on filament Nominal steps per mm (16x): 409 steps per mm Motor current: 1.Recommended Current: 1.40A Peak (~0.99A RMS).Startup voltage: 6 VDC (12V) and 12VDC (24V)Airflow: 6.8 CFM.Hemera must be mounted on a minimum of 2 mounting points, if using 2 mounting points, diagonally opposing points should be used, in order to ensure rigidity. The supplied M3×8 mounting screws are suitable for a nominal 5mm mounting plate thickness. The screws must protrude 3mm☐.25mm from the mounting surface to go into the T-slots. If mounting on the right, ensure that sufficient space is left for airflow. Typically Hemera is mounted onto the left side, as the air from the heatsink cooling fan exits on the right. ![]() Hemera is mounted to a flat surface via the T-slots on the left or right sides of the motor. Note, these are max ambient service temperatures of the components used,Īnd not a guaranteed operating temperature of the system Mass (Direct): 290 grams (Including V6 hotside).Recommended current: 1.4A Peak (~0.99 RMS).Max Printing Temperature: 300☌ (Upgradable to 500☌).Drive Type: dual drive with adjustable tension idler.
