I see your skirts and raise you one with a centered Hub and one piece 🙂 If only someone could make a 3 lane hub instead of a 4
Sadly, That as a little outside my depth right now

[primal cosmos]

thats why I didnt lol
so I didnt have to change the hub

[winged nebula]

Im gonna take a whack at it but I will likely butcher it all to hell lol

I also made front skirts for the BT Led logo skirts #1292367829198438481 message

[winged nebula]

I will also leave this here. BT leg mount for the 3 lane to sit nice and pretty on top of a micron print 4 two for each side The will require you to remove the Tpu feet though

[winged nebula]

Is it as clean as @primal cosmos. Absolutely no freaking way. Is it functional? Probably?

[winged nebula]

@calm bough If you get it printed before I do let me know if it needs work 😅

[calm bough]

the only possible problem I see if the filament coming in at a sharp angle a little curve on the outside might help it flow smoother.

[winged nebula]

Yeah I had to learn a bunch of new cad tricks to get it this far and trying to figure out how to smooth it out without frying my brain is challenging tonight

[calm bough]

haha you're doing great!

you're using fusion?

[winged nebula]

F360 yeah

[primal cosmos]

https://tenor.com/view/michael-jackson-comendo-picoca-gif-9669437860846841235

[winged nebula]

Well fusion crashed the moment I started trying to figure out loft so waiting for it to reopen. Thankfully I save very often. old school RPG paranoia to thank for that

[calm bough]

you know a sweep might be a better option in fusion

[calm bough]

If it's on the centerline, you can do the sweep and then mirror to get the other side.

[winged nebula]

Sweep is what I was trying to figure out when I started running out of brain power lol

[calm bough]

Just drop a construction plane in the middle of where the path needs to be, sketch the path you want the filament to travel and then select the circle path where it starts and then use the path. You can then tweak the path from there

Hope I’m being helpful

[winged nebula]

Figured out a way for me. I ended up removing the shafts from the ecas fittings and remaking them with much cleaner intersectiosn this time. without the jagged meeting lines. I was able to filet out the inside of the tube. Is that how its supposed to be done? probably not. Did it work. yes lol

[calm bough]

Looks clean

[winged nebula]

so this was the old one. While it looked good I didnt get them even and clean when poking the holes.

[rare axle]

If you haven't tried blended curve in fusion.. Definitely give it a try for stuff like that.. It works really well.. Pick the ends and it joins them with a nice curved path that you can then adjust further

[calm bough]

I’ll have to give that a try. Like I said I use soloists professionally so still learning little tricks in fusion

[rare axle]

Yeah it works really well... It's how I would do ducts on a toolhead I was working on, as well as modeling ptfe tubing or wiring etc.

[calm bough]

That's super slick, thanks for sharing!

[primal cosmos]

the combine tool is a drug

little doapamine hit every time

[winged nebula]

So hartk f360 tutorial series when? Thank you I'll give this a try again tonight 🙂

[calm bough]

@primal cosmos Would you be willing to share CAD for these?

[earnest stream]

here is latest hub for 3 lane with current d2hw switch configuration

[tall iron]

Does this use 1515 extrusions?

[calm bough]

It does not all extrusions for BT are 2020

[tall iron]

Oh ok i thought the printer with the red extrusions was a micron and someone made custom brackets to match the frame

I might try that with a 2-lane deal for my salad fork. I think 3 is too wide

[winged nebula]

Do you have the step for this? I am getting a weird click every time I load lane 3

[earnest stream]

@winged nebula yes ill send it to you when back at comp!

[winged nebula]

No rush! its not a huge issue I just cant tell much from slicer why It would be doing that

[earnest stream]

Likely due to the filament catching the wall after the bearing. The switch doesn't have as much tension as i would like it to.

[winged nebula]

Could you remove that and have a flared section of ptfe tube press against it?

[earnest stream]

I dont think that would work. Once u see the file it may make more sense. I may try to put the switch slightly deeper into the filament path. That way it keeps it preloaded a little bit to increase tension. Also what layer height did you print this at?

[winged nebula]

0.2

[earnest stream]

I found the best results with .12/.15. I don't recall mine clicking on any of the lanes. But on the six lane hub I did I know I had some similar issues and got to work best by reducing layer heights

[winged nebula]

Ill try reprinting it in the next few days or so and see how it does. saving the nice ecas I used is gonna be a pain XD

[earnest stream]

I feel that

[winged nebula]

I made the ptfe from extruder to hub slightly longer to give a straigher shot and havent heard the click yet so maybe that helped

[earnest stream]

Is the PTFE coming out of the hub beveled

[winged nebula]

slightly not a huge amount as the TN is maybe 10mm behind it

[earnest stream]

If you could chamfer/bevel the entrance of PTFE coming out of the hub I know that helps quite a bit.

[winged nebula]

Ill have to try that as it just caused a fail to load

[earnest stream]

any luck getting it figured out?

[winged nebula]

I didn't get a chance to try it last night. It's a 3mm Id bowden so shouldn't matter I don't think

[valid ermine]

I think this is the wrong spot for this discussion?

[winged nebula]

It's related to the three lane hub?

[valid ermine]

seems like more build speciifc debugging

[primal cosmos]

[crimson python]

would you mind sharing the CAD file for these mounts? I'm not using Voron spec Extrusion for the BT so they're extremely loose. Also I will need them to be taller it apears as I am running insulation

[winged nebula]

Yes I made a few changes since then so remind me tomorrow as I won't be near my pc tonight and I'll get them to you.

[crimson python]

Here is a reminder before I also forget

[winged nebula]

so you are saying the circled wall is where it crashes on its path in on lane 3? so need to find a way to smooth that out a bit better so it doesnt do that

[earnest stream]

correct. it would also be corrected with a higher tension on switch bearing. its kind of a flaw on the d2hw switch implementation

[winged nebula]

So I wonder if making it a slightly longer path out the back would help

[earnest stream]

i think longer straight before not after

[winged nebula]

how much longer you think? 3-5mm?

[earnest stream]

idk hard to say u get to long and the filament has top make a sharper transition. im order some springs i have a theory i wanna try

[winged nebula]

So this added 5mm before the bearing to give it a straighter run to it without really messing with the filament angles

[earnest stream]

id give that a shot that looks promising

[winged nebula]

Ill get it printed tonight while I figure out how to get the switch/ecas out of the old one. Im thinking a strategic use of hammer and chisel to take the printed part out while saving the hardware lol

[earnest stream]

hard to say tho looks like the outer lanes may run the filament into a wall

[earnest stream]

i used a flat head and worked my way around lolol

i also used an oven and softened the printed part and they come right out

both have worked for extraction hard to say witch is the better

[winged nebula]

ill find out tonight. At least they are the nice metal ones from W3d so probably a bit more durable

[crimson python]

Yeah ecas should just pry out really

[winged nebula]

Bench test with ecas and bearings seems promsing. Ill run a test print when I get home tomorrow. didnt click once and was much more centered coming out the rear ecas

[crimson python]

share the CAD for the centered exit 3 lane rear? Realized it doesn't have notches for the D2HW hubs

[winged nebula]

Cad or stl?

[crimson python]

CAD, I have the STL you posted but its missing features around the Hub

F3D file would be great if you modified it in fusion

[winged nebula]

The stl I made was the old style. Give me a bit ill export the new one from cad though I have the stl for that one as well

Though I'm not sure what features the new one is missing 🤔

[crimson python]

noticed that after the Hub wouldn't go in . oh that one looks right but it apparently hadn't been posted

[winged nebula]

I only made it like a week ago lol

[crimson python]

nice

[winged nebula]

I can still export the .step if you need it but it will have to be when I get back to my desk. out running errands

[crimson python]

that should do me, thank you though

[winged nebula]

👍

[crimson python]

That one works a treat, now hopefully the 3 lane hub is nice too lol maybe I can get this thing wired up this week

[winged nebula]

If you have issues with yours printing it at a lower layer height or I have one I modified might help

[crimson python]

Came out pretty nice after 4 tries 😅

[winged nebula]

Why four tries? Lol

[crimson python]

I messed up dimensions and didn’t realize your printer frame must be 10mm wider than mine so had to adjust for that too

[worldly saddle]

Is there a git for 🐜 sized bt parts or is it just the files here? I see a 3 lane hub and skirts so far

[calm bough]

I think gearnut had a git if I remember right

[crimson python]

all I've seen is what is here

[winged nebula]

Side skirts are same as the larger one. The front and rear skirts and hubs should be here as well. The frame is 90mm per lane and on top of a micron fits 3 lanes perfectly.

[worldly saddle]

anyone got a micron lightbox?

[winged nebula]

Like replacing the bt logo with a micron one?

[worldly saddle]

Yes

[winged nebula]

I could make one but it would likely be a few weeks.

[worldly saddle]

No rush

[worldly saddle]

any luck?

[winged nebula]

I will likely start this next week sometime

[worldly saddle]

Where did you end up powering the afc from the micron? USB? buck?

[grand cedar]

is that micron 120 or 180?

[runic mountain]

180
