Description
This macro creates an stl file with perfect rounding, i.e. without visible facets, from selected parts. It also allows to launch programs of your choice. For example to automate the FreeCAD → Slicer → printing workflow.
After the creation of the stl file you can, for example, open your slicer with the stl file, switch on your printer, heat the printer bed and, if necessary, trigger additional commands in your home automation.
Principle of smoothing
With visible facets
Without visible facets
The macro modifies the deviation property of the solids before creating the stl file and restores the original values afterwards. Next it can launch the stl file which will open for example under Cura, if the stl extension has been associated with that program on your operating system.
Launching other programs or commands
The macro can launch additional programs or commands that you might enter in a terminal:
- Turn on the printer and the light (requires a computer controlled socket).
- Connect Octoprint to the printer.
- Start preheating the printer bed.
- Save your FreeCAD and stl file somewhere.
Setup
Check that the stl extension is associated with your slicer on your operating system. In other words, when you double-click an stl file your slicer should open and load your stl file.
If you run the macro as it is, it will just create the stl without visible facets, but no others programs will be launched. For that you have to edit the lines of code that come after commands=[
in the section Parameters that can be changed. Have a look at the comments in the Code.
Usage
- Select one or more solid objects to print.
- Start the macro.
- The dialog opens:
- Check the desired options in the left column.
- Enter the Accuracy (param deviation):
- 0.5 is the default value in FreeCAD.
- 0.05 allows a stronger smoothing.
- 0.01 is perfect from a smoothing point of view.
- Press the OK button.
The lower the deviation, the better the quality, but the larger the size of the stl file. The value must be between 0 and 1
