[BUG] Lack of filament error with stock firmware 1.4.6 on Mega S #131

Open harry7922 opened 2 years ago

harry7922 commented 2 years ago

I installed the stock firmware for my Anycubic Mega S (no modifications). Since the update I receive the error "lack of filament or filament monitor abnormal". The error only shown after 5-10 layers of perfect printing. Filament was not runout.

Don't know how to handle this issue. With original firmware, everything works fine and also filament sensor is fine.

Steps to reproduce the behavior:

  1. Start printer
  2. Print any model
  3. Start printing
  4. Wait for printing first layers
  5. See error is shown in display and continue printing is not possible

This error should not occur since the filament really runout.

Photos of the print / output of the terminal If applicable, add photos or console outputs to help explain your problem.

Hi, have you found a solution?

harry7922 commented 1 year ago

No, I installed firmware of Knutwurst. Same issue there, but you can deactivate Filament Sensor in special menu.

Same here but I reinstalled the stock Anycubic I3 Mega S firmware thinking it was a firmware bug. Still getting the same filament sensor error so I unplugged the connector from the sensor and bypassed it with a small wire so the printer always read that there's filament in. Dont wanna spend money on a new sensor :) Just have to pay attention to print with enough filament lol
