Flow sensor for the UM3

[polygonfuture 12]

Hey everyone.   @Enigma_M4 @fbrc8-erin @3dprintz

 

I've successfully upgraded to S5 feeders on my UM3 with instructions from CarloK.    I've put together a detailed write-up for making the upgrades.  The doc is still a WIP and I'll be adding more photos, but thought this would be nice if anyone is adventurous.

I've been testing it for two weeks a now and so far so good!   It gives abrasion resistant feeders and flow sensor.  Also the S5 feeder is just way nicer to change filament using the new lever system.  The spring lever system of the stock UM3 is so poor in comparison.

 

NOTE:  This document is still a WIP.  There may be typos or small mistakes.   Please do this mod at your own discretion!   Its very simple but it does require one small modification to the ultimaker case, so it may void warranty if that matters to you.  More photos will be added in the coming days.  Also if you spot any errors in the doc let me know.

I can also make a new post if everyone feels that this is worthwhile.

Does it matter which S5 extruders you use? Cause there's R``1 and R2 versions.

UPDATE Nov 23, 2021:
@3dprintz

Based on CarloK's post on November 17th, I am using R1 feeder versions purchased from Erin's outfit at FBRC8 (I'm based in North America).  For now R1 is only supported for UM3 firmware 5.3.0. 

R2 should be supported in future updates but no official deadline has been set for this change.

Awesome! Thanks!

Some additional info on the S3/S5 feeders:

• The S3 and S5 use the same feeders.
• The feeders for the left and right side are different.
• Around June 2020 a new feeder revision was introduced: r2
• The r2 feeder better handles brittle materials. PVA filament got small cracks and to reduce this the feeder wheel was changed into a finer knurl pattern.
• The feeder revision code r1/r2 has no relation to the S5 revision code r1/r2
• For automatic detection of the different feeder wheels, the electronics was changed
• Both feeders should be the same revision level, mixing is not supported
• UM3 firmware v5.3.0 only supports the r1 revision

https://support.ultimaker.com/hc/en-us/articles/4408416927122-S-line-feeder-versions

 

I've made a note to support the r2 feeders in a next UM3 release, but no promises here.

Ordering codes:
203732 S5 feeder, left, rev.1

203733 S5 feeder, right, rev.1

225720 Feeder assembly left (1), rev.2, fine knurl
225719 Feeder assembly right (2), rev.2, fine knurl
225984 Fine knurl feeder kit (set containing both the left and right fine knurl feeders)

Thanks for the info CarloK.  I'll add this info into the doc for future as well.

@3dprntz Turns out I made a mistake on Feeder revision.  Based on CarloK's latest post, the part numbers I provided are for R1 feeders as R2 are not currently supported with UM3 5.3.0 firmware (but will be added in future firmware update). 

 

@CarloK What are the downsides of R1 feeder?  The issue is that the R1 feeders can create cracks in PVA filament?   Just asking so I know what to watch for in the future.

@polygonfuture Yep, the r1 feeder was updated because brittle materials like PVA got micro cracks in the filament. This can lead to filament breaks where retractions will be ineffective. Not a really big problem for the UM3, just some extra oozing, but in the Material Stations we do many more retracts and broken filament can get stuck at a location where you will have to dismantle the whole Material Station to fix it.
That's why for the Material Station people can receive a free replacement feeder, even after the warranty period.

Has anyone seen much of a difference between the two feeder? Just wondering if I should wait, or get the R1 Feeders.

[CarloK 201]

Go for the R1 feeders. A new UM3 release is not planned, so you could be waiting a long time.

Here is a picture of the difference for the feeders. Thought it also can be used as a stencil for the installation. Just needs to be resized correctly.

Great update! Is there any changes to the r1 or r2 feeders, or do we still have to go with the r1-Feeders?

excellent document, I cleared up some stuff which I did not know
