Bondtech BMG Mount for Seemecnc Effector Plate

thingiverse

I've been experimenting with an effector mounted Titan Aero on my Artemis printer, paired with a .9 pancake stepper from E3D. Meanwhile, on my Rostock Max, I'm using an effector mounted Bondtech BMG with a 1.8 stepper from RobotDigg. My observations and findings so far: Direct mounting on a large delta yields significantly better results than Bowden, even if you sacrifice speed and print height. A direct mount Bondtech BMG paired with a 1.8 stepper motor is an outstanding (perhaps the best) combination. Why this setup excels: The BMG is much easier to work with in terms of loading and unloading filament. 1.8 stepper motors also prove better for geared extruders, as they require fewer steps per 100mm. Up until now, I've been using Sublime Layers, aka Hackney's Bondtech mount, available on Thingiverse (https://www.thingiverse.com/thing:2445640). My custom-designed mount differs in several key ways: 1) The stepper mount is not integrated into the design; instead, it bolts onto a mounting plate. 2) There are two versions: one for melt-in nuts and another with through holes for 3mm bolts and lock nuts. This allows for more flexibility in assembly order. 3) Good clearance is provided for the BMG lever on a standard effector plate, and alternatives can be obtained from 713maker without needing a custom plate. 4) Bolts are used instead of machine screws for added security. 5) Cooling features may be added in future revisions.
