What are you using to cool the cold end?

The stock 30mm cooling fan that comes with the E3D V6

Gotcha..thanks!

Hey @yfaykya,
How did you go with the mgn12 mount? I want to use this on my Tronxy X5S with an e3dV6 hotend as a direct mount. I have converted my X axis to linear. If this has worked for you, it may be perfect for me to use on my Tronxy.
Thanks

Only noticed this now. I am actually only getting to it at the moment!

I did a quick remix for Volcano heater block. The first version I made was a bit short so I made a second version. But I have not tested it because I broke my 30x30 fan accidentally :(

BTW, even a m3x20 screw is not long enough to fasten the fan duct to the extruder all the way to the stepper. Not sure if there is a way to fix it without getting a longer screw.

Printing as I type! I modified it a bit to attach to a mgn12 carriage. So need to test it. Did you ever get around to making the fan duct for a volcano? Do you know what length I would need to add if not?
Thanks!!!!

I will double check my files when I get home, but I think I made a fan duct to test but didn't get around to printing it off. I ran a volcano hotend for a bit with the standard model and while it was short I didn't have any issues with it. I already switched back to a standard hotend. If I have it I will get it added

That would be much appreciated! Thanks again.

I checked and it wasn't a volcano fan mount I made. It looks like it will need to be about 8mm longer. I will whip one up in the next day or so

I botched one together using tinkercad. I will print and test and let you know. Thanks again!

Great model! Do I need to make any changes to calibrate the extruder? Any chance to have a EZABL sensor mount? Thanks a lot.

The BMG extruder is a 3:1 gear reduction so you will need to adjust your steps/mm for the extruder to 415 steps/mm. Plus its always good practice to calibrate your E-stops and flow when you make changes. As for the EZABL sensor it will work on the ABL model as they are both 18mm barrel sensors.

The stock screws for bmg don’t work. You’ll need 50 mm or more

Is there enough space for a 40x40 hotend fan?

it's quite easy to cut one wall below Nema17 motor (make it half of original hight) and use https://www.thingiverse.com/thing:1061896 with e3d plastic and 40mm fan - I use it (fan blows from right side - from below of motor).

Not really, but I will look into it some more. A mount and some short ducting might be able to work
