The speed will be lower because of the extra weight but I always print slower than 60 and with bigger nozzles… and I’m printing a lot with TPU nowadays shores of 85A, 95A and 98A (semi-flex) so this should be a good direction even to print TPE /softer and showned in some demos. Available as Bowden or Direct Drive means that the Hemera will retro fit many sub 250 printers such as the Tronxy X1 or Craz圓DPrint CZ-300 with a little. It’s a good option for me convert to 1.75mm filament because it’s almost impossible to find 2.85mm here and when I found it’s triple the price and has a lot of moisture due to low demand ? I also get an allmetal/ bimetal heatbreak to avoid the one with internal PTFE tube (it cames with Capricorn in a bore 4.1 heatbreak I guess). Smaller motor (weaker torch), but relation 7:1 and total extruder weight of 119 grams (photo bellow). It’s 92g lighter and 11mm shorter than classic Hemera, so it can move faster on your 3D printer’s motion system with less inertia, reducing print artefacts such as ghosting. Nowadays there is a newer and lighter extruder in the market, the H2 from Biqu, just got one. Revo Hemera XS is a compact dual-drive extrusion system.

Prints like a charm now (even flexibles). In retrospect I would recommend to start with a 3D-printed one. Also it's quite heavy and the included linear bearings are trash. There is also a aluminium head assembly on AliExpress, but be careful, you may have to modify (drill/mill) to get it working. I would also recommend to print everything from ABS or similar temperature stable.

My original design was quite laborious, but I found a more elegant solution based on ultiarjan's suggestion:ġ) tube-holder: reuses the bowden-tube as cable-guideĢ) Y-endstop-extender: BMG stepper motor will crash into the UM2 housing without it
HEMERA BOWDEN MOD
Sorry for the late reply, but I revised my mod quite a bit. Hello TheGrine, im interested in this configuration, could you please give me feedback of the configuration?
