Filament change suddenly happens in every print

Strange thing has happen for the last couple of days.
Suddenly all prints stops for filament change without a reason. The same happens both in Simplify3D and Sli3er PE.

I have searched for the M600 (that what I think after googling is the code for filament change) in the gcode but there there is no appearance of that.

What I can see it seems to happen every x meters of filament.

Mostly using octoprint but only have two plugins and that full screen camera and MQTT (And it worked before)

Anyone that can help me figuring out what the issue/setting is?

Re: Filament change suddenly happens in every print

probably due to your filament sensor mis reporting filament out!

the sensor may have difficulty reading shiny filaments,

have you tried cleaning the lens?
there is a hole for an air duster nozzle, behind the annoying little plug next to the filament entrance... you can aim the nozzle of an air duster can, in there to blow out the dust!

Thanks Joan but I have come a bit further

If i print directly from the SD Card it works as it should, but if I print using Octoprint this happens.
The same G-Code.

It seems like there is a setting in Octoprint that causes this but I can't find anything.

Any Idea?

Re: Filament change suddenly happens in every print

Sorry Martin,

I don't have a lot of experience with Octoprint.

to the best of my knowledge Octoprint puts more load on the einsy processor, maybe this is causing some sort of time out on the einsy making it unable to handle the filament sensors datastream, this in turn may be seen as not updating the filamentcondition registers, leading to a filament change error...

I would turn off the filament sensor, check that the print progress returns to normal, and report the findings on Git Hub.
