Anyway. This one has a weird feature compared to my other two. The main fan only activates when the extruder hits 50 degrees C. I know about this feature from Marlin of course, I just thought the UM2 wasn't able to use it.
This depends only on the revision of the main board. On the older boards (Rev. 2.1.1) the 5 Volt supply for the small fan is hard wired and not switchable. This has changed for newer boards, that are used for the UM2+ (Rev. 2.1.4).
A cheaper option for older machines would be a bimetallic temperature switch and a bit of tinkering, see here:
So if you go back even older, the first few thousand UM2s had a very very quiet 3rd fan. You really can't hear it. And it works just fine. So consider just buying 2 for your older UM2s:
I see. My newest one is probably a later batch then. I was hoping I had just missed something.
My other two are fairly quiet. My very first one was very loud but I didn't notice until I got my second one and realised how quiet it should be. I think the second one was pretty early because it had the very low light encased led strips. Anyway, I ordered a new fan for the loud printer and they are all just fine. Would have been even more quiet with it off though.
I might get one of those switches and mount on the side I guess. It won't fit on the top because I use Alexander Leisentritts modified print head. It's not a really big deal, just very nice that the fan shuts off when not in use.
S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
(Sorry, was out of office when this released)
This update is for...
All UltiMaker S series
New features
Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.
A year after the merger of Ultimaker and MakerBotQQ, we have unlocked the ability for users of our Method series printers to slice files using UltiMaker Cura. As of this release, users can find profiles for our Method and Method XL printers, as well as material profiles for ABS-R, ABS-CF, and RapidRinse. Meaning it’s now possible to use either Cura or the existing cloud-slicing software CloudPrint when printing with these printers or materials
