Description

Hopefully this will help clear some things up.



Update 2015-02-19: Added a new body with a cutout to use the grommet from the "new" feeders instead of a piece of bowden.
Update 2014-11-15: Uploaded length variations for the yoke, 35-40mm. I also added a zip with another version that has an included spacer for M16 screws so that you don't need to use washers. Six lengths included in the zip.
Update 2014-09-14: I updated the yoke a bit and made it longer as I noticed it was too short for NinjaFlex for me.
Update 2014-07-29: I've re-designed parts of the feeder to get rid of a
few parts that were causing people problems and also to strengthen it
slightly.

Right, here's my second (public) attempt at a new feeder design for the UM2. My goals were:
- Able to release the filament for quick and easy change between filaments.
- Re-use original parts from the old feeder.
- Try to minimize friction
- Supply additional guidance for flexible filaments (untested at this point and optional to install).

I've
been printing with this design for about 20 hours now without any
issues. That's not a guarantee that you wont have issues, no guarantees
here.

Instructions:
All parts should be printed in the
orientation that I've supplied them in. You should not use any support,
all the support is built into the files and should be fairly easy to
remove after printing. I would recommend a decent amount of infill for
strength, I've used 20% so far. I've used 0.08mm or 0.1mm layer height
and printed it fairly slow at 40mm/s.

On the arm there's a hole
for a nut. If it's tight, you can force it into place by inserting a
screw from the other side and screw it tight. If it's annoyingly loose
and wont stay in place once you're trying to secure the spring just use a
dab of glue. I managed to get it done with a nut that was floating
completely free in there though, your patience may vary ;)

On the
back of the case, at the entrance you'll find a cutout where you should
insert a short piece of bowden tube (you can cut off a small section
from your own tube, it will not hurt anything). Force it in with a
screwdriver or whatever and it'll snap into place.

You may find that the knurled sleeve isn't centered well with the bearing. Loosen the set screw that holds it in place and slide it in a few millimeters if needed.

Materials and methods

The parts from the old feeder plus one 30mm M3 and one 14(ish)mm M3 (I shimmed mine with a few washers to get the right length).

A very small section of the existing bowden tube for the entrance to the feeder (optional but recommended).

After having printing one for my UM3 after having feeder-issues with PolyFlex, it stroke me that this feeder might not be suitable to fit on a UM3, so hence my question: can I put this on a UM3 without any modifications, and can I expect trouble from doing so?

Thanks for designing, though the grommet version is too weak where the new gap is. Printed three now with ever increasing strength settings but the bottom 'nut hole' snaps off every time with standard PLA, even with plenty of walls and fill. :(

Hey Robert! I love this feeder and we recently got an SLA printer. I don't suppose you have a support-free version? The supports don't come off quite so easily with an SLA part, but I suspect the resin print will stand the test of time more than my first PLA version!

I did, for some reason it appears that filament is pushing against the

bottom of the bowden tube and rhen causing it to push out. I replaced the

bowden tube today and its still happening along with under extrusion.

Did you put the white bowden grip and the blue bowden clip to keep it in place? Both pieces are part of the original feeder

Ah, I somehow missed that. Ended up taking the metal ring from the bottom of the stock feeder and putting it in Roberts feeder. Works like a charm; no more noise!

Did you place the piece of bowden tube at the bottom of the feeder? Read the instructions and look at the video around 23-24 seconds

Printed this on my UM2Go and have been using it for a couple days. I printed and tested all of the different yokes and settled on the 38mm. I'm having an issue where I get random squeaky noises from the feeder, almost like a creaking sound, but not always. Is this normal or is it indicative of a less than optimized spring tension? I am also using the snap on guide.

Depends. If you usually print with PLA then print this piece with PLA. Over time you will have some material from the feeder get in the tube so if you printed it in ABS it might clog the nozzle because your printing to low to melt it.

Quick Question. What is the recommended material to use when making/printing this feeder? PLA? ABS?

have printed it, looks very good - The idea of the "snap on guide" is not clear for me. Why did you not integrate the guide into feeder body? If it would be integrated, you can see the filament and notice if the feeder grinds into the filament. Maybe I missed a point ?!

Feedback:
I made some small modifications, A gave it a metal sleeve to prevent small pieces of plastic wearing off and spoil the color of the print. the metal seems a bit to long but the length made it easier to print soft filament. To do so you also have to change the tension so a small knurled wheel works better.

Very nice, i cannot believe ultimaker design their feeder that way, this is what i need. I cannot believe ultimaker 2 plus did not copy this, why? they copy olsson block, why not this? they expect us to unscrew and tickle with the stepper motor everytime we have problem with feeding and need to clean it. Everybody should change their ultimaker 2 with this and olsson block. You just need to buy one 40-50mm and 15mm M3 screws and M3 nut from the hardware store.

Mini reiner 001 2Reiner Bühl commented ago

I tried that one before and did have issues with it. I couldn't get the bowden tube piece sit correctly and it caused me some grinding because of that. I have one version with grommet which works fine but now I need a second one but seemed to be unable to print a reliable one anymore.

Mini loggaIRobertI commented ago

Use "Feeder V6 Body" instead and insert a piece of bowden tube instead of the grommet. That version is better IMHO and will be a lot stronger in that area so you shouldn't have any problems with breakage at that point.

Mini reiner 001 2Reiner Bühl commented ago

I have a lot of problems with the body with grommet. It breaks at the "bridge" where the grommet is inserted. This happens often already when removing the support structure in the screw hole next to it and even before inserting the grommet. I tried ABS and PLA with varying infill values. Would it be possible for you to upload a version that is a little bit stronger in that area?

I had printed and used this design on my Ultimaker for a while and its awesome. Since I always wanted to print something in metal, and this is so useful I decided to send it to shapeways and have it printed in metal. Its interesting to see how the material informs the shape as it could be much less bulky done in metal

Thanks for this awesome design!

After several hours of succesfull prints the filament starts to slip inwards from the bearing... :-( Happened after filament change. I am using the low friction spoolholder as well.

Any ideas whats going wrong would be highly appreceated!

I have been using this alternate feeder (extruder), with a couple of minor upgrades, for a couple of months now, and it's brilliant. Kudos to @IRobertI - thanks for completely solving my underextrusion issues!

Works great. Thanks Robert. On a UM2 i use the 38mm yoke-n-hub as suggested by Robert. The original feeder's bearing is fastened with a 10mm piece of filament, that fits tight in the hub and yoke - no use for a bolt there. The yoke itself is fastened with a 40mm x 3mm bolt and some rings to make it all fit

That is in fact the only part you have to buy with this design: a 40mm x 3mm bolt and some rings.

@Ross Fischer, people kept complaining that that piece was too short, or too long. So I made a bunch. Try the 38mm one.

There are many "Yoke and Hub" pieces with different measurements in mm. Is that for different diameter bearings?

Mini south park iconEd Driesen commented ago

Christian,

If the filament gets "eaten" (local indentation, wear) your screw is to tight. If i'ts to loose, it wil skid (because of the resistance bowden/hotend).

Both will result in to slow movement.

btw, I'm printing a year with this extruder and no problems here.... You just need to develop some "fingershpizengefhul" to tweak it.

Mini img 1638pmdude commented ago

Sorry but your comment is unclear. What is the problem? Do you have problem with the spring tension or do you have problem with the screw holding the spring or with the screw holding the bearing?

Hello,

I installed the new feeder, but the screw in the left with the spring.It’s well? I entered the filament but is slow.What can I do? Could you advise me how should I do? Thank you very much.

I had the same issues as described by freaksed. Often, the filament snapped with a loud bang when there was resistance in the bowden or nozzle. With the improved yoke, issue is now resolved.

I slapped one on my Frankenstein UM Original with an MK7 gear that I had laying around. I also had to add a 4mm Nema 17 suport under the feeder to clear the lip on the UM Original (https://www.youmagine.com/designs/stepper-motor-nema-17-support). It works pretty good. I've had the motor slip a bit, and am thinking of adding a high torque 60mm stepper.

I've had issues for 2 weeks which seems infinite when you print every day. This is the only feeder that gave me excellent results (i've tried 6 different solutions even with mk8 and mk7 gears). It works very well, and is very convenient. The option to remove the filament when something is stranded is very useful (you no more grind on your filament when sometimes you have to pull it off!). You load and unload filament in a breeze. It prints flexible filament like charm. This is definitely THE UM2 feeder for me. Thanks a lot Robert !
