CURA auto bed level BEFORE heating extruder MACosx

Posted · CURA auto bed level BEFORE heating extruder MACosx

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.

If you dont put your own M104 S0  M140 S0 right after the G28, cura will will insert them at 1st layer temps.

You will need to put the M104 M140 later in the start codes else cura will not heat the bed/extruder.
