Hello Raise 3D,
I have a problem and need your help. I was printing and everything was good. Last detail was done and then printer was on during weekend. When I wanted to reprint the same detail on Monday morning, filament does not flow well enough. Detail and raft of course were so soft. Yesterday I checked secondary nozzle and it is the same. Please advise.
Thank you
Sergey

Do a unclogging first with the metal rod. https://www.youtube.com/watch?v=o-3GuO_eiRA
If still not good, then may need to take everything of the hotend apart, burn or bake it to melt the filament inside and then install back to check whether it improves. Watch out the thorat tube, it is very easy to be broken if apply any improper force.

Re: Does not flow well
It is not clogging, this is the point

Re: Does not flow well
Has the hotend been taken apart to check whether there is anything side yet? Maybe not fully clogged, still can extrusion a little but can't reach to the full-extrusion level.
What about the nozzle cooling fans? Are they keeping on blowing cooling air to the heat sink of the hotend to keep the throat tube at low temperature even the nozzle is heating?
Have you ever tried hand push the filament during printing to check whether the extrusion amount increase or not?

Re: Does not flow well
Everything looks normal. Yesterday I measured extruding filament. When I pushed it down it was .45 +/-, when it was extruding by itself, it was .23 to .34. I think it does don grab and does not push it. How I said in my first post, I also tried right nozzle, the same thing. Maybe be rotation gear speed is not fast enough.

Re: Does not flow well
If push down can extruder filament properly, then normally should be due to improper distance between feeding gear and guiding bearing. Loose the fixing screws of the extruder motor and move the gear closer to the bearing.
Re: Does not flow well
First of all I change original extruder to Bondtech. How I said before, everything looks good. What I did on Friday, I increase Flowrate in Filament setting to 110%. Detail was printed. However, I'd like to change it back. Please advise. Thanks
Re: Does not flow well
Printed another detail. Prints well but 10% heavier.

Re: Does not flow well
All the files were the same gcode files which can be printed out properly before? Haven't edited any setting or resliced yet?
Re: Does not flow well
Everything was the same. It's started to print bad just soddenly. Then I added 10% flowrate and it is started to print well just 10% heavier

Re: Does not flow well
What about your StepE? Has it been edited in ideaMaker or touchscreen? If I can ask pictures about them?
Or may I see your gcode file?
And the serial log of your machine after reboot, as well maybe?

Re: Does not flow well
Vicky, I just changed flowrate back to 100% and it works. Thank you
