update: Great extruder after some tweaks and deburring of the plastic housing! I now have two 😁(on both of my printers) Note; I thought that i ordered exactly the same extruder when I ordered the second one, but when closely examined, there are some small (internal) differences like the gear @7:33 being easily removable on one extruder (axle clicks in place), and not removable at all on the other extruder (at least, I didn't dare to bend the plastic so far so I could get the axle out)
I purchased a BMG clone and it just has 1 gear pushing the filament... I was wondering what all the hype was about until I saw this video. I guess I got a bad clone lol.
Aren't there any problems with the gear mesh being dependent on filament diameter / pressure on the filament? Usually gears are quite sensitive to gear mesh. Errors lead to uneven movement.
Ok you just saved me I got 4 of these and when I set one up on my cr10 mini and did a calibration it was like oh crap this thing is junk but I didn’t think about the massive gear ratio. Back to the drawing board. 🤣👍👍 thanks
I enjoyed your video, better the others I have watched. I have a question though. I know you have to change the esteps to around 415, but what about retraction, specfically direct drive. I currently use 0.5mm distance and around 25mm/s for the speed. Do these change with a bmg or stay the same.
I am pretty sure you are running it backwards although I cant see it making a difference apart from you wont have to change the motor direction in FW or the wiring
These things slip when pushing an insane amount of filament into something like a volcano at ridiculous speeds. For most people though, this is more than enough. Fun fact. If you buy two cheap AliExpress BMGs, you can create a housing that allows you to turn it into a quad drive extruder. More grip than the Bondtech LGX for a fraction of the price
I did install it and I tested it out for about a day or two. It's really good for what you're paying. However, I'm waiting on some M10x1 bottoming taps to come in because the threads on the Bowden tube side are tapered, so my compression fittings won't go in until I tap those threads. I could use a pneumatic coupler, but chose to wait until I can fit the compression fittings instead
@@andrewesquivel I have the money to buy any of them I suppose I just don't like overpaying for every addition to my printer, if this performs better than the dual geared extruder I'm using I will be happy. I've been sourcing silent fans lately and it is a tiresome task. It's difficult to find ball bearing based, low amperage fans in various sizes which meet the CFM requirements while remaining under 25dB.
If you fitted this type of extruder then you might have to modify the stepper motor wires otherwise this type of extruder won’t work as it’s not plug and play
Actually these have Proven to be Far less than Advertising.. hype and Shills Claimed. A simple stuupid single gear Mk8 extruder simply produces a Better print. The gears are Eentric.. True. Their gear teeth mesh poorly just to add insult to injury. Both bungles generate visble Z banding effets on ones' print.. Ohh Joy! The unloved E3D Titan is a FAR more capable extruder.. Simply beause it has ONLY one drive gear.
