TL-BMG-V2 Universal Geared Extruder Dual Drive for 3D Printer

I don’t ever write reviews but this one just picked me up from the gutter. Was pulling my hair out trying to get my damn printer working right. Removed my crappy stock plastic single gear and found the lever was cracked! No wonder the underextrusion.I’m on my first print with this BMG (which is an actual TriangleLabs) and it looks pretty good without changing any settings. Fits Ender 3 v2 perfectly without any mod/bracket etc.Couple things I’ve read — i) obviously redo e-steps… should be up around 400s after; ii) load some filament through then tighten the tensioner screw in all the way. Back it off 1-2 full turns for rigid filament and 3-4 full turns for flexible; iii) might make a clicking noise at higher speed, so lower retraction speed to 20-30mm/s; iv) even if you think it’s obvious how to install and get it goin… just obsessively read a bunch of posts on the BMG. Some good tips in there ¯\_(ツ)_/¯::)

So I bought this to replace the extruder on my Anycubic Mega X since the one it came with decided to fall apart (I’m using a bowden extruder system). How did I install it? I ended up putting it on so the words AREN’T upside down like you may have seen some people do on youtube when installing (installing it with the words upside down makes it feed backwards, logically).For the process I went through I had to do some searching, so now I’m typing my process out below so people don’t need to search.At first it worked great, then it started slipping, did some research, needed to adjust e-steps (that’s the number of times the motor turns the gear in the extruder to feed the filament into the hotend). I happened to already have Simplify3D so I plugged the printer into my PC, started Simplify3D, went to Tools > Machine Control Panel, set the port to COM3, unchecked Verbose, go to Communications tab and click Connect (it worked one day and didn’t the day before, Idk). After that I follow Thomas Salanderer’s E-step calibration video and ended up with a new E-Step number of ~377mm/s (from the manufacturer the Mega X is apparently set to 400mm/s which is… impressive(?) for a non-dual drive extruder from what I’ve read) once I had the number to input I typed in the code for the new steps (M92E377 for me) then put in command M500. It should save the settings, but just in case send code M501 (this will call up the data you saw when you first connected BUT with your new E-Step value). Restart your printer, reconnect to your computer and double check that the value remained the same. Then do a test print, and you SHOULD be good.Happy Printing!

Seems to be a quality product for the price. There was a lot of play with the gear attached to the arm, and I've seen videos where people use a really small piece of bowden tube to make a little washer. So I was prepared to do that when I assembled mine but there was what I thought would be a better fix for it (maybe). The kit comes with a flat white washer that is supposed to go under the arm spring. I simply used that instead to remove the play in the gear and it fit perfectly. I guess I might print a washer down the line if the spring needs it, but everything seems to be working great with this set up.

No es buen estrusor, es mejor el que viene de serie en la ender3
