You might need a higher force pressing against the knurled wheel. Normally the motor should slip instead of grinding. What happened with you was that the knurls could not grab deep enough into the filament and thus lost traction and grinded the filament away.

Do you use an Infill over 24%? That could explain your issues with the infill.

Just uploaded Version 3.1.1 of my Feeder. It is as always in my Siqnature Have fun and please give me some feedback.

I just needed to print this as lover of Sim City and Sim City 2000. Such sweet times with those games

Do you know how much torgue you would have to overcome if the feeder was powered? Or Resistace in the Nozzle? Also if you need something US based i would advise to use this model: http://deezmaker.com/store/#!/~/product/category=0&id=24043350 Also i ordered the MK8 from my previous post and will soon begin testing it out on a UM2.

I am currently on my Project for improving the Fan Cooling. Here is the improved nozzleshield to prevent the Nozzle from cooling to much

I will just leave these links here: http://reprap.me/extruder/mk8.html http://reprap.org/wiki/Drive-gear *flies away Edit: for your enjoyment

Increase that to 2-2.1mm by turning the metal coupler clockwise..... you can use the holes in it to do so.

Abstract how much space is between the metal coupler and the teflon piece on your machine?

@Mark What is your ambient temp?

Sort off..... it is still a very simple gear So if anybody wants it i have a download of all the needed parts here: https://dl.dropboxusercontent.com/u/90634021/Inbus-Holder.zip But be aware that is not perfect yet.

And i am Back to the Roots...... Skipping @3mm like in the beginning The only things i noticed are the Bowden tube has worn down quite a bit and the teflon piece at the extruder widened up to 3.4mm... otherwise everything seems fine. But both reasons should not get the feeder to skip....

Actually it was my mistake.... it cant fit on the second feeders place..... was a slight error i really have to correct ;D

I was working on something practical the last days. An Inbus holder that lets you rotate the inbus keys so you can get the smaller ones out easier... i needed a whole battery of gears to get it so that ,if you rotate one inbus, all rotate.

Btw just asking but is someone even using my version of the feeder?

They should really ship a nice piece of 0.1mm metalsheet with the machine

Could you pls explain what these 3 mean in detail? Filament Extruder (a real filament producing machine or a improved Version of the Extruder for the UM2?) Make a 3D Print using UM2 (A Guide?) Back Supporter Equipment(?) Maybe you guys could get another nice project what has been on my list for a while but is not due till i think something like late fall this year: http://umforum.ultimaker.com/index.php?/topic/4811-thinking-about-redesigning-the-side-fan-trays-for-um2/

You vaping?

Your print speed should improve drastically if you would move the feeder onto the extruder like here: http://umforum.ultimaker.com/index.php?/topic/3261-ultimaker-2-extrusion-problem/&do=findComment&comment=46577 I have seen how good flex materials are printable on machines with extruders that had their feeder directly built above them..... it limits your speed naturally but should improve overall speed with flex mats by a great deal.

I have no intention to quit....

It is an E-Cig.... yes i vape But i am also one with the force ;D

Since i lost the last one i printed i needed to reprint it.

Very interesting..... if done right this could improve printing of Flex filaments in terms of speed and extrusion reliability by 3-4 times, maybe even more... though i have some concerns about the stress that is put on the belts with higher speeds.... also the smaller rods could bend over time which would be a dire situation. But i have some ideas how to eliminate these risks though. Atleast for flexible filaments this could be a very viable solution.

So then post the model online and see what Ultimakers can do Or just send 2-3 Volunteers the file. I would agree to print this and take some pics. Btw the upper part in your picture is more or less very hard for any printer to print nicely if not impossible.... the lower part is not easy either....

Also take into account that with option 2 you loose the rectraction...
