filament stop feeding after one hour printing .....

[bipbay]

Guys , the filament just stop feeding after one hour of printing ... I only have 20 more min to finish !!!
Is there any way I can back step a couple step in the g code ?
I found that the filament will always stop feeding at around a hour or so every time, is it somthing wrong in my setting ?
I'm using SFACT slicing
High quality - no support
Layer height 0.1mm
Filament Diameter 1.75mm
E-step corrector 1.02
Feedrate : 200( on the manual control speed Multipuly )
Flowrate : 114 ( on the manual control speed Multipuly )
What are those ? I just know the bigger the number the faster it goes , but does it matter ? what are the ratio on those two ?
Extruder temp : 195
Speed 200mm/min
Heat bed temp : 55
Fan at 100% always
thanks guys

Is the tension on the fillament bearing enough? Does the extruder motor skip steps?

There is a way to resume a failed print. Please read my tutorial:

Hi, this has startet happening to me also. I rinced the hot end twice. It seems right and I start again. After a while it just works in the air. Thread is fine, not to strecheted, not too loose.
Did you find the problem?
