[Flow sensor for the UM2+ (and even perhaps for the UM3) - Call for pilot users]

@gr5 thanks I will PM you thanks appreciate it. I have a few USB-to-serial but I think since yours is a tested version might be a good to have item.

 

This will help me see (i hope) what address i2c expects but I just realize I dont have any spare encoder. Maybe I should get the UM2 kit from @foehnsturm ?

I believe so, yes.  But I think you want to edit um3.json.  Not um3.json.log.  The file is here:

/usr/share/griffin/griffin/machines/

 

 

 

Thats the correct filename i used. Its just the forum wont play nice uploading.json file. It only allows other extension and .log

Usually it's better to just sit down with the hardware spec sheet and write up the code for the actual device being used. That way you reduce the number of "surprises" when things aren't *quite* the same. At least that's the answer if you do this for a living ....

 

 

 

I Agree as well, we need to know if they left the procedure for the filament flow. I will dig in the rest of the files but I would be a lot easier if we have the FW or at least the copy and not play with the live printer. Tho I'll just watch @gr5 video how to unbrick I guess

I think the B option makes more sense if we are to make this a plug n' play solution (we dont want to brick UM3 ? ). I have a few teensy,esp32,uno,adafruit variant lying around. I think I can Frankenstein something hahaha but I havent checked the config if we can enable the flow sensor on the fly like how we change e-steps for the bondtech extruder. And I am not so expert I may need someone to point me where to start ?

 

EDIT:

many might already know this but this is good news (to me).

um3.json.log

"feature_filament_flow_sensor": false,

Just need the rest of the FW I guess

Hi, I have been a long time member and lurker but I think this will be my time to help the community. Sadly I sold off my UM2E clone but I have my UM3 (with bondtech DDG)

 

I know HW and solution for FW is not yet available for UM3/E but you can list me as an interested party for when UM3 test is ready. I am not an advance python programmer but can have my way on a python/arduino/c code if needed.

 

Like the others I am very excited for this project.

[Print orientation and MeshMixer vs Cura supports]

Very Nice print. I've been a lurker and only been a member recently but this prints kinda inspire me to do better next time. Hope to see the larger print.
