I didn't know that one yet Maybe Jennyprinter will offer a UM2+ upgrade kit with just the feeder - unlike Ultimaker who plan to rip off all customers that already have a UM2 with Olsson Block by paying for another one... sorry, I am getting off topic...

As far as I understand, the Tunell sensor manages to detect at least jammed nozzles and extreme feeder grinding without help from the firmware by measuring filament movement trough the sensor over time. If no noticeable movement forward is detected over a configurable number of seconds, it changes t...

This one is for 1. and 2., the thread for 3. is here.

1. and 2. are kind of related since both sensors, the Tunell and the Sparkfun, are detecting end of spool and total jamming while the Sparfun sensor detects a few conditions in the middle too.

As said by the Neotko and Amedee, your follow-the-sun moderation concept needs staff

Okay, then it shouldn't be an issue to use that one on the UMO too. The code I have seen mainly adds a function checkFilamentSensor(); to the manage_inactivity() funtion in Marlin_main.cpp. This function checks the pin where the sensor is connected and then uses lcd_print_pause() to pause the print.

TinkerGnome added the support for such a sensor - or a simpler, optical sensor that just detects filament/no filament - in his fork of the UM2 firmware. The changes do not look too complex, so as long as you have a free I/O pin on the UMO mainboard, it might be possible to also include this. In the ...

Thanks for offering your help!

The sparklab sensor seems to work only in conjunction with some firmware modifications that provide data to the sensor. The tunell sensor seems to work standalone and only needs firmware support for a filament runout sensor.

Interesting... I will have a closer look on it. As long as it can produce a high -> low signal when something goes wrong, it should work with the UM2 and TinkerGNome Firmware.

The thing should be roughly the size of a can of Coke but lighter and costs $65. They want between $45-$175 for shipping it to Germany while shipping for customers in the US is free.

Hi all,

I would like to add a Tunell Filament Monitor to my UM2 but they seem to be only available in the US. International shipping starts at prices that are close to a flight ticket from Europe to the US
Does anybody know of a European shop that sells it?

Best regards,
Reiner

That would be parallel but the snap locks don't take the vibrations too well I assume. Soldering is more stable.

Don't change too much right now. You have done amazing in just a few weeks. Let it settle for a while! Even god apparently rested on the 7th day

Has anybody checked if this shop is not one of Thingiverse's "partners"? Thingiverse and partners have the right to use your items. For all others the CC license is to obey. Here in Germany, the CC licenses have already been ruled valid in front of courts, so it would be easy to get money ...

What's the best way to splice into an existing fan wire? Such little wires give me anxiety! I think that's the problem with this snap lock, the wires are so tiny Do you want to splice them parallel or serial? If parallel: I would separate the red and black if they are together first. Then cut the e...

I noticed such bits comming of sometimes too, but only when applying the glue over existing glue e.g. when crossing over previously applied lines of glue.
