ULTIMAKER S5 EXTRUDER 1 - MATERIAL ERROR

[ANCAME_UMS5 0]

Hi Guys, I am new to this forum and would like to post an issue that i have been experiencing.

 

Please see attached photos of the error message. This happened a few times under difference circumstances.

1. When we changed to a new spool of material and the material extruded fine after loading the material. After that, this error occurs when the print actually started. The printed was aborted and restarted multiple times without success.
2. Sometimes this error occurs during printing. The printer thinks that the current spool is empty but it is not. Not sure why
3. Extruder 1 has got a brand new AA 0.4MM print core, thus there is nothing wrong there

 

Originally I thought the feeder has mechanical issues, and then I pulled apart the feeder 1 and check against the feed 2 and everything seems to be in good order. Recently I have come crossed an article about the FLOW SENSOR. Therefore, I had done a test to DISABLE to flow sensor

 

As a result of this test, the extruder 1 printed fine with one small (6 hours) and large print (17 hours). So I was wondering if the FLOW SENSOR was faulty or sth, but it did not give me the usual flow sensor faulty error code.

Please help if you have experienced similar issues and advise a possible fix for it. Much appreciated for your input. Thank you.

Hi

I have had the little connector on the back of the extruder work its way loose a couple of times which as I remember gave this error.  More often though it has been the extruder wearing a groove (not always a big obvious groove) in the filament when retracting either lots of times in a small area or because the filament sticks in the core a bit.  Also check your front fan is switching on at 40C nozzle temp.

 

Hope this helps

Hi Mrender,

 

Thanks for your reply and suggestions. I will check that definitely. For now, I have disabled flow sensor and both printer cores are printing fine so far. I have ordered a new flow sensor and new fan which will be replaced and test again.

With regards to the groove, is it possible to share any photos of the groove you are referring to ?

Hi, I too am experiencing this issue. Can you please provide an update? Did the new flow sensor solve the problem? Thanks
