Anet A8 J-Head compatible mount (supports E3D v5/v6 etc) UPDATED by werto165

Last crawled date: 3 years ago

DISCLAIMER: I haven't actually attached this to my printer as I'm waiting for some fittings for the rest of the bowden setup, however there's nothing that I see that could be an issue.
I've installed it into my printer and realised that it triggers the end stop 12.5mm before it should so I would use the G28 (to home) and then M206 command to see what your current offsets are if there are any say your offset is X-40 Y-20 Z0 Then I would change it to X-24
My settings are X-14 Y-20 Z0.
I printed my design in simplify 3d however I imagine other slicers would work too, supports will be needed for the main bracket and also the front of the clamp, the goal of this design was to make a j-head mount that was as light as possible and for it to support the popular
"Spriya" - High Efficiency Anet A8 Fan Duct" found here:

I just used the method that original metal mount used for attaching the belts to the carriage which is using a screw and a nut, you can use the ones that came with the printer to achieve this.
To attach the fan I'm going to be using some left over parts that I had from the printer, namely the M3x30 screws for attaching the part cooling fan, you'll probably need to print off a spacer if you're using nyloc nuts like I am however it's not required. It's just a measure to make the nyloc nuts last a tiny bit longer.
As far as I'm aware the print head is the exact same place as the bone stock version so you won't need to make any alterations in the firmware for extruder offsets. However I may redesign this with option of having two j heads on one carriage, in that case there will need to be an offset.
If you have any questions, or possible improvements for this design leave them in the comments.
Try and follow the same supports as I've done in simplify3d however, supports are not needed for the Knurled Screw.

If you need a E3D V5 clone fusion file like the one I used to design your own x-carriage then you can find that here: https://www.thingiverse.com/thing:2456199
I noticed that the screw that I originally uploaded had a 3mm across flats head so I changed it and uploaded two, one that's 2.55mm that I imagine will work with most printers (2.4mm being the head size I was aiming for) and 2.45 if you're feeling adventurous.
I've updated it to have a more substantial fan holder as the previous one was quite prone to wiggling, I've also accomodated for the endstop position so you no longer get prints that are offset.
