Hold hang wires at the top of the rods

Picture explains it all.
Simple small and very practical for my ROBO.
Tight fit both for the rod and the cable.
This one is Model1.STL

 

I like it though only problem I'd see is that you lose some Z height with that mod. You'll want to lower the maximum Z in Repetier (or whatever software you're using)

I went a different way. I created this on thingiverse http://www.thingiverse.com/thing:209034 which is a rebuild of this item http://www.thingiverse.com/thing:162100 but I wanted it to be a bit thicker so it supported things better. It holds the cable against one of the Z motors. You want to have the Robo at it's Z max height before attaching it so that it doesn't have to strain against the cable. No loss of Z height.

 

Yes you loose some mm's of the height.
How ever, from what i see in your model is that it travels with theextruder allowing the cable to slide up and down.
I my case there is no slide at all thus no friction.
Cable stays put at the top and as it goes down it bends just far enough to be right above the extruder.

I do want to see how it works at the very top, but am printing right now with CURA. Cura does seem to have better drive that has no connection issues or "command waiting" garbage that i see with repetier all day long.

 

i've been hanging my wires with a cable tie from day 1.
my Robo 3D cover is off as i had a lot of tampering to do
never got to putting it back

 

Do you ever get slippage on feeding that way ?
My roll hanging directly above the cutout and recently started to skip

 

my roll is hanging to the back of the printer.
i don't have any slipping issues, they never touch

 

What is that thing called that pulls filament into the nozzle ? That rod with threads inside the extruder rotated by the gear ?

 

you mean the Hobbed bolt ?

 

yeah. somehow its not catching the filament.
I tried to tighten it it more against the gear with 13mm wrench socket but it didnt help.
I ended up removing sprigs from retaining screws and put some spacers instead to create more tension.
It does flow OK now, but i dont think it should need so much force to pull 1 kilo ROBO ABS roll hanging directly above with little to no resistance at all.

Perhaps there are mods to help ?

 

I'm guessing it one of two,
either your filament is too thin
or your hot end is clogged
the tension the springs are providing should be more than enough to hold the filament against the hobbed bolt

if you want, you can drill so that the screws with springs can go all the way to their ends. but there is no need for that

 

the bolt was not tightened all the way. Gear was kinda wobbling slightly.
But tightening it didnt help so i tightened the bearing pushing filament.
Filament is OK, its from ROBO guys.
Slippage would take place every time bolt makes complete turn, always at the same spot.

It wasnt like that when i started to successfully print anything (yesterday), but today it started to act.

 

You can also have issues if it's too tight and thus shaving filament material by the hobbed bolt. Look at the bolt. Is there powdered filament material? If so, it's shaving. You want to clear all of that dust out. I personally use a cotton swap with nothing on it to clear it out and make sure the spaces between the grooves are clear.

Its all clear after i clean it up. It does shave every complete turn as if it not perfectly round.
I think i need new design bolt
