Parameters of UM2 feeder spring?

[reibuehl 42]

Hi all,

I am trying to find out the parameters of the feeder spring used in the latest UM2 - or a place where I can buy one for a decent price and shipping cost. Ultimaker itself seems to be not able to ship me one nor tell me what it would cost...

I found three different documents that talk about different part numbers and different springs:

https://github.com/Ultimaker/Ultimaker2/blob/master/_BOM/BOM%20ultimaker%202.pdf - part# 1140 - spring named D2110

https://github.com/Ultimaker/Ultimaker2/blob/master/um2%20assembly%20manual%20V1.1%20_english.pdf - part# 1143 - spring named DR2110

https://github.com/Ultimaker/Ultimaker2/blob/master/1311_Spring_D2000_(x1)/B1311-Z2P-A.pdf - part# 1311 - spring named D2000

The names of the springs seem to point to Alcomex as the manufacturer (http://alcomex.nl/wp-content/uploads/2014/07/Druckfedern_DE.pdf), but since I do not know, which of the three I should get, I can't look for local alternatives based on the Alcomex parameters.

Can anybody here shed some light on the part number confusion?

Best regards,

Reiner.

The D2000 one is the one found in the printer head, not in the feeder.

The D2110 is the correct one, apparently it's missing from the UM2 files, but it's data is found at the UMO files (as it's also used in the UMO)

Thanks for confirming the right part, Daid. Can you comment on my assumption that the spring is the D2110 from Alcomex that is listed in http://alcomex.nl/wp-content/uploads/2014/07/Drukveren-20from-20Catalogus-20NL-2005.pdf?

I'm not allowed to tell which suppliers we use. But that part from alcomex has the same specs as the part we use ;-)
