Cura 3.4.1 Cooling fan stops/starts intermittently

Recommended Posts

Anet A8, Octoprint. During print cooling fan stops for a second then starts again intermittently. Fan LED on the board turns OFF in that moment and than turns ON again. Analyzed g-code Cura generated and found multiple blocks with M107 - M106 commands. So Cura does turn fan off/on during print. Is that normal?  How to disable it?

Apparently hidden experimental option "Enable Bridge Settings" enabled by default.


It's not enabled by default:


                    "label": "Enable Bridge Settings",
                    "description": "Detect bridges and modify print speed, flow and fan settings while bridges are printed.",
                    "type": "bool",
                    "default_value": false,
                    "settable_per_mesh": true,
                    "settable_per_extruder": false,
                    "settable_per_meshgroup": false

The default value is false so you must have enabled it yourself.

      A: Materials which are hard in a solid piece (like metals, ceramics and carbon fibers) will generally also wear down the nozzle. In general one should assume...

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
