Should be interesting to see what you come up with, that is friggin' light.

I managed to shave about 50-60 grams off of the stock effector/hotend with the one I designed for my dragon hotend, probably could have made it lighter but I tend to overbuild things to make up for my lack of engineering knowledge. Not completely happy with the design, so I haven't bothered publishing it.

I've been digging around a bit and I have at least narrowed down what I'm going to use for my axis motors.

  1. The 1704HSM168RE, known good pretty awesome motor but 20% more expensive than a comparable motor.
  2. The LDO-42STH47-1684MAC, basically the same motor spec wise except the holding torque says 4.0Kg/cm(70 Oz-in) which has to be a typo, 70 Oz-in would actually be around 5.1Kg/cm.
  3. The 42HM48-2404 which appears to be superior to both motors if the spec sheet is to be believed, it's a no name motor but at least the seller on Aliexpress is one of the reputable ones.

I'm probably overthinking this, just about any 48mm 0.9 degree motor should be more fine for what I'm doing. I'm going to go get some work done outside and let a random number generator decide for me if I haven't made up my mind when I'm done.
