The last step is to save your print job so that you can later transfer it to the printer. The save icon in the left toolbar allows you to both save a job (.nxa) and the scene (.nxs). Remember that the print job is the file your printer will use to create the part, whereas the scene file is a project file that lets you resume where you left off in NexaX. Saving a job file will automatically save a scene file as well.
Clicking the button will pop up a text field for you to name your print file. If it is your first time saving a job, it will prompt you to select a default save folder where all your jobs will save to. NexaX will create a subdirectory within here with the name you chose with several files inside:
- Print Job (.nxa)
- Data folder
- Scene File (.nxs)
- Information Text file (.txt) - resin info, models included, print time and volume
- Preview Image (.png) - picture of your scene
Change Default Save Folder
When you save your first file in NexaX, it prompts you select a default save folder where all your jobs are saved to. If you would like to change this directory, click on the small gear icon in the top right of the save menu. It will bring up a File Explorer window for you to select a new directory.
As mentioned above, this is a project file that you can later import into NexaX to resume where you left off and continue making edits. You do not have to save a scene if you already saved the job. However, if you would like to just create the scene, click Save Scene. Unlike saving a job, this will pop up a File Explorer window for you to both select a save location for and name this specific file.
After saving a job, a preview box will appear in the bottom left corner. This box will show the image the printer will expose at a specific layer (known as a slice). You can control which layer you want to see by moving the layers slides on the right up/down. You can compare the slice to the cross section of the part in the viewfinder to see if they match up. You will especially want to do this if there are concerns about the .stl quality of the file.
You will have noticed that in the Details menu on the right, there was a Print Time parameter. Before saving, this field shows an estimate of the print time denoted by "~" (ex: ~00:33). After you have saved, this value will change to the actual print time (ex: ).
