hi i made a remix just wanted to say sorry as it didnt list it as a remix from my phone . i have added your details now .Wayne

Hi :)

Nice job, i'll probably print it in near days !

Why do we have to "swap the middle 2 pin on the 6pin end" ?

Thanks!

Because the stock wire did =)

Ok I see ^^"

I'd like to remix your file to be compatible with Alfawise U20/30 (Longer) : place for small hole, lagers holes for motor mounts, wires holder, etc.
Could you please share the stock 3D source file ? It's complicated to edit the mesh STL :x

Thanks!

Thanks for this design , it works really well. I even adapted my Hero Me ducting to fit with it .
What retraction settings are you using now ? I started a test print with 2 mm and I was going to work from there but I'd love to know what your settings are .

Hello. How did you adapt the Hero Me duct? :)

Retraction - 7mm length & 45mm/s on stock ^^

"adapted my Hero Me ducting to fit with it" glad to know it works for you!

Looks good - I just started researching BMG extruder and this will make it possible! However my printer doesn't show up until tomorrow. :P

Have a great print!

does it interfere with the hero me v2 dual blower ?

Yes I'm pretty sure it will.

Ooh been looking for a mount for a while to try, was about to have a go designing. However looks like it will affect the BL Touch mount. Guess I can add a washer or could you extend the fitting down to cover teh lower screw hold, then the standard BL Touch mount would screw on top.

Sorry I don't have a BLtouch on hand for testing but I added a BLtouch version based on salcatroppa's mount. you might give it try :)

Cool, will give it a try at the weekend, many thanks

Ok all mounted, however BL Touch mount needs to be 4mm lower. Its way too high for a V3.

I made one with 4mm lower like you said, may you please test it for me? thank you so much!

This is now perfect, many thanks for the changes, posted my make

Are any setting changes required for it's install? Is there any extra hardware required?

Yes you need to change the e-step when you replace the stock exturder to BMG or clone BMG, I'm using 415 at the moment:

Also:

1) replace the little screw with a longer one M3 x 6
2) longer XH2.54 4pin - 6 pin wire around 100cm. swap the middle 2 pin on the 6pin end.

Regarding my question about needing additional hardware?

there are no descriptions of any requirements for this part other than the design. It would be helpful to know the total package for the solution to work for anybody else.
I do understand that you'd steps component because it is a change from stock to a BMG I already have the BMG.

updated please check description :)
