[Start Gcode - 4.0 vs 4.2 (Ender 3)]

My first print with Cura 4.2.1 didn't insert the correct temperatures. I inserted the old gcode, tested, and it worked. 

I repasted the cura 4.2 start code, and tested - and then the temps worked. 

 

Don't know what happened to fix it. 

[Start Gcode - 4.0 vs 4.2 (Ender 3)]

I've noticed that with Cura 4.2, my temps did not get set on my printer. When checking the Start Gcode, there is nothing to set the temps. 

I've realised the start gcode from 4.2 is quite different to 4.0. 
Should I be adding the temp gcode from Cura 4.0 into my start gcode in 4.2?

[Dynamic Line Width for custom profile]

51 minutes ago, nallath said:

Yes, don't put an override value in your profiles. Then it will use the default, which in this case is a dynamic value.

Thank you. 
 

Is there any way to change the formula, like nozzle_diameter_size*1.2 for example. 

[Dynamic Line Width for custom profile]

Hi there,

I recently switched to Cura 4.2. 

 

If I use default profiles, and change the nozzle size, the line width automatically adapts. 

If I then change the line width manually, it shows the setting as something like: “=nozzle_width_diameter*1.1”. 
So it seems line width is somehow dynamic for the default profiles. 

 

Is there anyway to retain this behaviour on my custom profiles? 
Thanks.
