Feeder for Flexible Filament

[Ronan 58]

Anyone know of a feeder replacement for the Ultimaker 2 for printing (a lot) of flexible filaments (ninjaflex/filaflex)?

After 2 days of finicking with it, it's just a pain, not realistically possible to print a lot. So a new feeder is needed, preferably one that attaches to the hot end to eliminate the bowden.

Thanks

If I would need flexible 24h rght now I would go for a pancake feeder motor withthe e3d titan extruder and build an adapter to install it on top of the um2 hotend.

If you can wait someday anders will finish his design (or publish it).

I need it by the end of the week, hopefully he is done soon! Great news to hear he is nearly done

Thanks neotko!

If anyone else knows, please do share

Another option for you now would be to buy a Flex3Drive and then print one of the UM2 replacement heads.

i had hazzle free prints with ninjaflex and the bondtech extruder. Also swapped the PFA bowden for a PTFE bowden. not the one from bondtech, which has a too large inner diameter. Worked at first try.

Which bowden did you swap it with? This was for a UM2? Also you changed the hot end?

Thanks

Oh, I thought I had linked the shop: www.2printbeta.de If you are in the US, you can just look for 1/4" outer diameter, 1/8" inner diameter ptfe tubes.

And yes, i have a UM2 with ollson block.

Don't bother with printing with bowden if you require a lot of retractions. If it's a simple shape then you can get it to work quite well but you really need a head mounted feeder or flex drive if you require good retractions.

I use Roberts feeder which works well for me with the snap on guide, use a little oil in the Bowden tube to reduce friction.
