Welcome to the SeeMeCNC Community

I dont have a laser cutter Dan, but i'll see what I can do about milling these out at a lower cost but $20 wont even cover the cost of the tooling. Unless there are more people interested.

some more progress on the all aluminum magnet joints compatible with seemecnc parts.

testing fit up little more than a pound of weight

test fitting all aluminum hot end mount prototype . compatible with xnarons conversion.

Well, if you plan of selling a complete kit, i'm buying. I'm pretty sure i'll eventually be able to make mine work..i think!

Cambo3d, I am confused how your effector works. Xnaron's mount the balls at an approximate 30 degree angle,
yours appears to be flat. How has the testing gone on your aluminum version?

Preliminary fit up of the bottom mounted direct drive extruder. the hole for the filament is not in the center but i'll try it anyway till that gets fixed.

compared to the weight of stock stepper of 332grams. this weighs about 226grams, around 240grams with the magnet ball joints installed. not to much lighter but with all the fans/heatsinks installed it should still be under 300 grams.
will need to modify the extruder mount and reprint so the hole is centered. or modify the aluminum affector

dont think i'll be selling kits, just some parts I make.

the angle of the balls helps with clearance when at the extreme ends of travel. but looking at the design i dont think it will interfere. i'm still testing and fitting up at this point

You'll almost certainly need a heat sink on the PG35L, and possibly a fan which will add to the weight a little.
Are you intending the bend the mounting points as seen on the BerryBot, or are you going to have it remain flat?

Planning on keeping it flat for now. Will know better once its all fitted up.

doing some research on these little motors. they seem to be unipolar, instead of bipolar. our controllers are bipolar type, I think.
Is this why this motor runs hot?

I've been brainstorming on how to mount these http://forum.seemecnc.com/viewtopic.php ... 320#p11149 hall effect switches.

I have some so so ideas but wanted to see how you guys would do it. Maybe help me come up with a better solution.

What have you come up with so far? Maybe we can embellish it.

Sensors look like they're panel mount, so I'd print a panel for it to mount at the top of the towers. Secure panel to side of tower with t-slot nut and bolt, since cheapskates don't go all the way up the tower it shouldn't hit. Then print a magnet mount that takes a 6-32 screw so it can screw in stock hole where the end stop screw goes.

hmm working out the the fit..but i came with up something that mounts it to the outside of the frame. while keeping the stock switch in place for now.... for testing purposes.

some eye candy. continued from here. http://forum.seemecnc.com/viewtopic.php ... 360#p12644
got the heat sink, fans and some 3mm filament in today. Looking good to so far, I should be getting the 3m epoxy dp420 adhesive for the mag joints also and I'll be almost ready for test run

Do you mind giving your source for the heat sinks you show on the motors?

i use rc motor heatsinks 540/550 size. bought from ebay but you can get them at most hobby stores.

all metal hotend goodness

Awesome. Can't wait till my E3D gets here.

using the kossel mount for jhead from thingiverse. milled out of aluminum.

Wow that kossel mount looks great. Put it all together already!

i would but i dont have the correct size tap for the bowden fitting yet. its on order though.

Maybe someone else has posted this already, but when tapping the e3d hotend for the quickfit connectors, I'm assuming youd have to drill the top to match the tap, right? Then would a bottoming tap be required or would a standard tapered tap be ok?

im not tapping my ed3, i'm tapping my aluminum mount for the bowden adapter, the ed3 sits inside my aluminum mount no tapping necessary. I actually located a the correct tap. didn't have to order it after all.

But to answer the other method. Yes, it must meet a flat bottom in the barrel. And the barrel must be totally perfectly free of any edges or ledges. Cambo3d's solution is not only better but far easier to pull of perfectly and not affect your hotend performance at all.
