Any good light weight direct extruder/hot-end?
-
i did look at the nimble before getting the flex3drive , but the design of the flexdrive seemed more robust , and i noticed dc42 used flexdrive extruder on his delta kits
i could not be happier at this point had a couple so spools of filement through it so far and no clogs , filement path has zero restriction when changing material , even flex materials have no problems

@martink1974 Heh, I started with the Flex3Drive but had issues both with customer service and robustness. Sounds like they got those things sorted out.

Flex3Drive have a ~75g nema direct extruder listed on their web site

Edit: this is the single nema8 extruder, very reasonable price and ~75g https://flex3drive.com/product/g5-nema8-extruder/

@zapta , that will be gr8 for some machines , that motor iis tiny , not sure if vibes from stepper would effect the delta with smart effector setup i use, but this looks gr8 idea

Zesty just posted a design for a nema8 adapter. https://www.thingiverse.com/thing:3856292

I own a nimble and two of the new open source G5 flex3drives the flex3drives worked out of the box and delivered perfect extrusions, which the nimble did not, I messed about with it for 3 months support sent me some new gears but it was the same, It suffered with a weave pattern on all prints and uneven extrusions, The nimble sits in its box collecting dust while the flex3drives are used daily with no problems, And now the flex3drive is open source you can buy the parts and print your own in FDM or SLS / A
Ive always found the support from flex3drive good not that I needed it much.flex3drive

There was clearly something wrong with your setup of the Nimble.
I have installed three and they all have worked fine.
I'm going to try one of the new Flexdrive units once they are available. They appear to be a good improvement on the original design.

I have three nimble's too, never had an issue. Brian and a likle are real engineers who know what they are doing.
I had a single flex drive before the nimble's, I had nothing but trouble with it, trouble the owner (Jason I think) of flexdrive did his level best to blame on everything but his product, suffice to say the P.O.S. flex drive lies in a storage bin somewhere.
Admittedly nimble's require you to know what you are doing to get them set up, but that's not the products fault if someone can't test and analyse things.

I can assure you that I tried many different configs and setups to remedy the problem with my nimble, and have seen many pictures of people with the same or similar problems, to the best of my knowledge no one has solved this problem to date,
Stating that you need to be an expert or have a lot of knowledge to setup a nimble will just put beginners and new users off. -
I never said anyone needed to be an expert though did I.?
I was however trying to be polite about people's abilities.....

Locked before this becomes a nimble Vs flex3drive argument.
