CURA auto bed level BEFORE heating extruder MACosx

Recommended Posts

hi! this has been answered before but i cannot seem to find where the input area is for MACOSX. If i enter the code into Machine settings area "start g-code" the machine STILL overrides and start heating the extruder. I dont want it to heat the extruder first, but rather start the AUTO LEVEL BED and then heat up extruder afterward. Could someone please shed some light on this?


thank you!

The settings page should be the same on Windows and MacOS and I can remember that there was a thread some days ago about this topic. So check the search function if you find the thread.


Besides that, I personally don't think it is a good idea to manipulate the start sequence, because there is a reason why Ultimaker heats up the extruder before the auto leveling. I think I have read that the nozzle needs to be heated that the measurement is accurate enough.

    • "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.
