Troubleshooting

When an upload is refused

This is binary G-code (.bgcode)

PrusaSlicer saved binary G-code. In Printers → General → Firmware (Printer Settings in older versions), untick Supports binary G-code, or untick Use binary G-code when the printer supports it in Preferences → Other. Export again, and upload the .gcode. Step by step, or watch it (1 min) (opens in a new tab).

This project isn't sliced yet

A .3mf downloaded from MakerWorld or Printables, or saved as a project, holds the model, not the toolpath. Open it in Bambu Studio or OrcaSlicer, slice it, and choose Export plate sliced file. In PrusaSlicer, slice it and choose Export G-code. How, and what to do if it's greyed out.

We can't render this file

An STL, OBJ or STEP file is a model: it has no toolpath to render. Slice it, then upload the .gcode or .gcode.3mf. Why G-code.

This file is too large

Files can be up to 100 MB. A .gcode.3mf is compressed, so it's often much smaller than the same .gcode. Or slice a plate with one copy of the product.

This file can't be opened

The .gcode.3mf is damaged or incomplete, often after a download or a copy that stopped halfway. Export it again from your slicer.

This file doesn't print anything

The file has no printing moves, which usually means an empty plate was exported. Check the plate in your slicer, slice it, and export again.

This G-code is in inches

The G-code is in inches. Set your slicer to millimeters, export again, and upload the new file.

We can't reach the renderer

The renderer didn't answer. Your file is fine: try again in a minute. Write to support@extrudio.site if it keeps happening.

We're in private testing

Uploads were for invited testers during the private test. Everyone signed in can upload now, so write to support@extrudio.site if you see this.

Sign in to upload

Uploading needs an account. Sign in with a code by email or with Google, then drop the file again.

The upload didn't go through

The upload stopped before it finished. Check your connection and try again.

The upload took too long

The upload's link expired before the file arrived, which happens with a large file on a slow connection. Try again: a .gcode.3mf is smaller to send.

Something went wrong on our side

Something failed on our side. Try again in a few minutes, and write to support@extrudio.site if it keeps failing.

We couldn't read this file

We couldn't read the file. Export it again from your slicer and upload the new one. Write to support@extrudio.site if it still fails.

Notes about your file

The file check notes anything unusual it read. Most notes need nothing from you.

Part of the print has no feature labels

That's normal for FullControl or other custom G-code. We render every line as printed, so there's nothing to do.

The header's layer count doesn't match the file

It happens when G-code is edited or joined. We render the layers the file really has.

Some moves use a label we don't know yet

We render them like the rest of the print. If the preview looks wrong, write to support@extrudio.site with your slicer's name and version.

The file doesn't mark its layers

We found the layers from height changes, so the printer's own start and end moves may show in the render. A file from Bambu Studio, OrcaSlicer or PrusaSlicer marks its layers.

The header's height doesn't match the file

We render what's printed, so there's nothing to do.

Some line widths don't match the plastic laid down

Those lines may render a little thicker or thinner than printed. Check the preview: it's usually harmless.

The file doesn't say its filament diameter

We assumed the usual diameter to work out the line widths. If you print with another one, set it in your slicer and export again.

Nothing in the file lays down plastic

Export the sliced print, not an empty plate.

The print swaps filament by hand

The render shows each tool in one filament, so the bands above a color change show in the tool's filament, not the one you'll swap in.

Filament changes are flushed into the print

The real print has blended bands there. The render shows each tool in its own filament.

Filament changes are flushed into the infill

That's inside the print, so the render doesn't change.

Too detailed to render

A render holds a limited number of vertices, and this print needs more. Slice a plate with one copy of the product, or use a thicker layer height, then upload it again.

When a preview doesn't show

Choose a plate to see a preview

This file has several plates. Choose the one to render, above the preview.

Multi-color prints preview in one color for now

A print with several filaments previews in one color for now. Its final images show every color.

The renderer isn't reachable, so there's no preview

The renderer isn't answering. Your setup is kept: try again in a minute.

Previews are open to invited testers for now

Previews were for invited testers during the private test. Everyone signed in has them now, so write to support@extrudio.site if you see this.

Sign in to see previews

Previews need an account. Sign in, and your setup is kept.

Rendering is paused, so there's no preview for now

Rendering is paused for a while. Your setup is kept, and previews come back when rendering resumes.

A rendering limit is reached, so there's no preview for now

Your account has used today's previews, or a limit for everyone is reached. Previews come back the next day, and final renders don't depend on them.

This print doesn't suit the scene, so there's no preview

Each set is made for prints within a range of sizes, and this one is outside it. Choose another scene, such as a studio backdrop.

This print is too detailed to render, so there's no preview

This print needs more detail than a render holds. Slice a plate with one copy of the product, or use a thicker layer height, then upload it again.

The preview didn't render. Your final render can still go ahead.

This preview didn't render. Try another one, or go ahead with the final render: it doesn't depend on the preview.

When an image fails

Ran out of memory at this size.

The image ran out of memory at its size. Retry it, which is free, or choose a smaller size or a lower quality.

The render failed.

Retry it: retrying a failed image is free. Write to support@extrudio.site if it fails again.

The render took too long.

It took too long and was stopped. Retry it for free, and write to support@extrudio.site if it happens again.

When a video fails

Rendering failed

Your credits come back. Make the video again.

This print is too detailed to turn in a video

Your credits come back. The print needs more detail than a video holds: slice a plate with one copy of the product, or use a thicker layer height, then upload it again.

Its parts couldn't be put together

Your credits come back. Make the video again.

It took too long, so it was stopped

It was stopped, and your credits come back. Make the video again.

The close-up's point missed the print

Your credits come back. Aim the close-up at the print itself, then make the video again.
