    Cura 3.6.0 Ender 3 start code changes

    Hi, I found that the order of the start g-code seems to be the issue. It sets the bed temp and waits for it to reach the target temp before it sets the hotend temp. Was this an intended change? For something Like ABS is would actually make more sense as the bed takes a while to heat up to 110C. is there a setting to change this behavior?
  2. Good day. I am very new to 3d printing and still learning alot about slicing and printing. I enjoy using Cura and I can see the amount of development going into it. I noticed that upgrading to Cura 3.6.0 brought changes to the start code of my Ender 3 machine profile. I noticed that when I start a print with a file sliced in 3.6.0 the hotend temp was not being set, although the bed temp was set. I upgraded my Firmware to Original Marlin 1.1.9 (from Creality firmware) before upgraded Cura from 3.5.1 to 3.6.0. I also use Octoprint to print via USB. Naturally I am looking at the firmware, but in searching for the issue I tried to print an older file sliced with Cura 3.5.1 and the hotend temp was being set. I looked at the start g-code of the two files and found a difference as below. Manually changing the 3.6.0 file's start code to look like the 3.5.1 code worked. After I added the heating code back to the machine profile in Cura it added the code including the new 3.6.0 code. Could the firmware still be at fault? Where is the temp code, before the custom start code, set? Can I remove it and only keep the machine profile's start code?
