First Layer Temperature

[LePaul 321]

This is one that's had me stumped for a while.

 

In another slicer (S3D), I can set the first layer to be different (hotter) than the following layers. 

 

For example, with PLA, I would usually do the first layer 5 C hotter, then on layer 2, reduce it.

 

The Setting seems to point to something I just can not locate in the long list of setting controls.

sounds like...

• UM2 (+)
• and G-code flavor still set to "Ultimaker 2"

❔

 

"Nozzle Temperature Control" is usually enabled for all G-code flavors except "Ultimaker 2".

With "Ultimaker 2" some of the material settings are handled by the printer (as you probably know...).

 

G-code flavor can be changed in the machine settings.

Right, I was hopeful that I could do something like this with Cura's UM2 profile, since it's very convenient for that first layer to be a little hotter.

I have not an Ultimaker2 but changing the Gcode Flavor in the printer settings has other consequences as this value is checked to allow other parameters than the Nozzle Temp,  modify start and end Gcode...

 

You'd better create a new definition file :

ultimaker2_0.def.json  

in your AppData\Roaming\cura\4.0\definitions folder (if you have Cura 4.0 on a Windows7 OS)

 

content below

 

Quote

{
    "version": 2,
    "name": "Ultimaker 2_0 (NozzleTempEnabled)",
    "inherits": "ultimaker2",
    "metadata": {
        "author": "Myself !!!!",
        "visible": true
    },
    "overrides": {
        "machine_nozzle_temp_enabled": {
            "value": true
        }
    }
}

 

 

Then restart Cura and that's it, you can create your own UM2 printer
