Hello friends.

I'm stuck with a cura error message. Themessage is:

"Unable to slice with current settings. The following settings have  errors:"

Small layer printing temperature.


I tried with a lot of different values, but none seemed to solve the error.


I enclose my project.

Could someone give me ideas about how to get rid of the error?


Thanks in advance for your support.

    I got errors loading your project file. Cura will only load the model. Looking in your file I recognize that something is wrong with your your setup files.  E.g. it seems to miss your quality profiles and your material profile seems to be as well not complete. You should ask your printer manufacturer for working printer definitions.


    Meanwhile you can try to set the Small layer printing temperature to the normal print temperature from the involved material profile. Check your printer profile in case you want to know how the calculation for this entry is defined. The entry is called "cool_min_temperature". You will find it in the printer definition file.

    Thanks for the report.
    I wasn't aware this setting existed. Here are a couple of lines from the fdmprinter file.
    "value": "material_print_temperature",
    "enabled": "cool_min_layer_time > 0",
    "minimum_value": "max(material_final_print_temperature, material_initial_print_temperature)",
    "maximum_value": "material_print_temperature",
    With my print temperature at 210, Initial Printing Temperature 205, and Final Printing Temperature at 200 I can set the Small Layer Print Temperature between 205 (the larger of the other two settings) and 210 (the Print Temperature). When I sliced a model with those settings, near the end of the gcode Cura inserted M104 lines and the temperature stepped down incrementally from 210 to 205 over the course of the last few layers.

    In regards to this bug report - It appears that if the Initial Print Temperature, Print Temperature, and Final Print Temperature aren't configured correctly (the boxes turn yellow) that it causes Small Layer Print Temperature to be in error and Cura won't slice. I don't know why it's set up that way but it makes it appear that what you have is a well hidden "expected behavior".
    The Tooltip text doesn't mention the connection with Initial or Final print temperature and it appears that it should.
    I think the Cura team is busy getting ready to release 5.3.2 but maybe @MariMakes or someone else from the
    team can chime in on this.

    Easy option 1: lower your initial printing temperature.
    Option 2: Change your max/min into a warning.

    • Go to the following folder C:\Program Files\UltiMaker Cura 5.3.0\share\cura\resources\definitions
    • To find the following file fdmprinter.def.json
    • Find the Small Layer Printing Temperature definition
    • Change "minimum_value" to "minimum_value_warning" and "maximum_value" to "maximum_value_warning"
    • Save the file and restart Cura to slice

    Balicki gave a way to definitely bypassing the error. Neverthless I greatly appreciated the GregValiant contribution, that explained the rules that different temperatures should obey, in order to not rise the error.

    Thanks to both.
