Fixing "G-code path conflicts" slicer errors

Getting a "G-code path conflicts were detected" error when slicing? This guide explains what it means and how to fix it.

What does this error mean?

This error occurs when the slicer detects that the toolpaths (the paths your printer's nozzle will follow) overlap or collide with each other. This typically happens when models or the wipe tower are placed too close together, causing their generated G-code paths to interfere.

How to fix it

1. Move models further apart

The most common cause is models placed too close together on the build plate.

1. Go back to the prepare view
2. Select the models that were mentioned in the error
3. Move them further apart so there's more clearance between them
4. Slice again

2. Move the wipe tower

If you're using multi-color or multi-material printing, the wipe tower may be too close to your models. SimplyPrint uses slightly more conservative wipe tower parameters during upload, so a layout that works locally might cause conflicts in the cloud slicer.

1. Look for the wipe tower on your build plate
2. Drag it to a position further from your models
3. Slice again

3. Reduce model count per plate

If your build plate is crowded, try splitting your print into multiple batches with fewer models per plate.
