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). Nowadays there is a newer and lighter extruder in the market, the H2 from Biqu, just got one.
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

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?
