Not extruding, with no reasonable excuse

Hello all,

First post here, probably wont be the last lol.

Well I have a problem with my printer not extruding during printing. It started after 2 days after setting up octoprint to control my CR10S. I was able to print without issue for numerous prints, and then it just stopped extruding.

-The extruder drive gear turns and retracts but no filiment extrudes.

  • Filament extrudes when directed to manually through octoprint or the printers control even immediately after failing to extrude like the above.
  • Tested varying degrees of pressure on the filament idler with the extruder just kicking and still failing to act properly.
  • Performed cold pulls as well as completely clearing the nozzle. Eventually replaced the nozzle. no difference noted.
    -Updated to the most current TH3D firmware with no difference coming from it.
  • Printing works off and on with working to not working times currently being 3 days on 2 weeks off.
  • Installed stepper driver buffers on x, y, and extruder motors, with no difference noted to performance besides the higher frequency noises silencing notably.
  • I'm running the stock cr10s PLA at 210c-220c with the filament almost pouring out, and hatchbox pla at 200-210c. Temperature hasnt appeared to be a cause due to by running the same file through different temps made no difference.

Below is a same of a print of mine running Hatchbox PLA at 200c at 50mm/s. No filament was extruding 5 minutes into the actual print(post preheat), so the bottom section is after i cancelled. The settings ran on this print I have run on 5 prints with this PLA in the past 4 days, but now it doesnt work, and this is the cycle I have been experiencing for months.

PLEASE HAAAAAALPPP.

Changing monitoring state from "Cancelling" to "Operational"

Hello @Jday!

Obviously not an OctoPrint issue.

You may check that the nozzle is not clogged.

If it is a firmware issue, you should ask TH3D

is the gcode sample indicating normal extrusion speed?

For I don't have a CR10S I can't tell - sorry.

And there is no filament at all coming out of the nozzle? Not a single drop?
