I don't think it should have any impact, but in my case there was a marked improvement with this change) reverse the way the stepper motor was plugged in and set it to inverted in marlin config (no why this helped. adjust the supply current to the extruder I was able to make a few changes which significantly helped things in my tests: I've discussed this with a friend who also recently upgraded to a Hemera and he's seen similar issues with his machine (Ender 5) and it looks like there's a few other people complaining of similar issues in this and other forums as well. It also seems like a heat creep issue, but sticking a thermistor into the heatsink or between the motor and backing plate only shows 40-45C (this is admittedly not a great way to take a reading, but it's all I have). It prints great for a while and then stops extruding.Īt first I thought my nozzle was clogging, but after messing around with it some more I'm pretty sure that's not the case as I can't extrude after a jam, but if I manually pull the material out and feed it back in it's fine for a few more minutes.
This happened three times so I switched to a newer roll of 3DSolutech PLA (200C hotend) and saw the same issue as with the Raptor PLA.
I then switched to some old MakerGeeks Raptor PLA (235C hotend) and started to have issues with the extrusion stopping suddenly a few hours into a print.
#E3d hemera extruder upgrade#
After the upgrade I printed for about 20 hours using PETG without any issues (240C hotend). Therefore, Hemera is not compatible with other NEMA 17 motors and you will not be able to swap the motor with either a compact but powerful, slimline motor or other 3rd party motors.I just upgraded my AM8 with a Hemera hotend and I'm running into some trouble with extruding PLA. Whilst Hemera’s custom motor is similar to a NEMA 17, it isn’t a standard NEMA 17. Design choices such as die-casting custom motor faceplates and heatsinks have enabled us to provide high quality, consistent parts at an affordable price point. Accessible pricing for every userĮ3D’s manufacturing capabilities have significantly increased over the years.
Our parts work together with known tolerances and guaranteed compatibility, so there is no risk of purchasing a component from a 3rd party that doesn’t quite work. Hemera is a compact single unit built under one roof by one engineering team. Integration is key to a responsive extrusion system. The T slot mounting system means you can easily design mounts for your 3D printer or choose from a selection of pre-designed mount adaptors to get you set up as quickly as possible. Print PLA at 600mm3/min with the standard V6 heater block or scale up to print carbon fibre reinforced PEEK at 6600mm3/m at 450C with the SuperVolcano HeaterBlock and NozzleX. Upgradable for all performance requirementsīuilt around the E3D ecosystem, Hemera is adaptable to meet whatever performance requirements you may need. It provides excellent grip strength, outperforming the competition with 98.07N maximum pushing force, meaning you can extrude at high flow rates with minimised risk of stripping filament. Hemera is the most powerful extruder on the market. Looking to upgrade your printer with a next-generation extrusion system? Hemera is a compact, dual-drive extrusion system that combines our V6 HotEnd with an all-new filament drive to form a highly responsive direct drive extrusion system - providing unrivalled performance with flexible filaments.
