In TruTops V6 with Service Pack 4, creating a GEO file does not by itself produce the machine-ready LST file for a Trumatic L3003. Load the GEO into the machining workflow, define the material and operations, then generate the NC output.
GEO and LST File Roles
| File | Role in the documented workflow |
|---|---|
| GEO | Geometry loaded into TruTops for machining preparation. |
| LST | Completed machine program produced when TruTops generates the NC output. |
If TruTops creates the GEO but no LST, confirm that the job has progressed beyond geometry creation into the machining and NC-generation stages.
Generate the LST File
- Open Technology and load the GEO file.
- Select the material configuration, including sheet, bar, or tube and the required thickness.
- Position the part.
- Open the machining section and select the required tools.
- Create the machining operations manually or automatically.
- Optimize the operation sequence, including reordering tool changes when required.
- Select the command to generate the NC output. This creates the LST file.
Verify and Transfer the Output
Record the selected output location when generating the NC program, then confirm that the LST file exists there. Transfer that LST file to the Trumatic L3003 using the site's established machine-transfer method.
If no LST appears, check that the GEO was loaded into the machining workflow, material and tools were selected, machining operations were created, and NC generation completed. The evidence does not identify a specific error code, output-path default, postprocessor setting, or compatibility limitation, so verify those items in the installed TruTops configuration if the workflow still produces no file.
FAQ
Why does TruTops create a GEO file but no LST file?
The GEO contains geometry; it is not the completed machine program. Load it under Technology, define the machining operations, and generate the NC output to create the LST.
Which TruTops command creates the LST file?
Use the NC-generation command after selecting the material, positioning the part, choosing tools, and creating the machining operations.
Where is the generated TruTops LST file stored?
It is written to the output location selected during NC generation. Note that location when creating the file, because the evidence does not specify a default directory.
