Compatibility "V400 compatible only in accessory mode"

Hi Mark, thanks for reaching out!

Accessory Mode is our solution for when a USB connection between Palette and your printer is not possible due to hardware or firmware incompatibilities. If you select accessory mode when slicing your project in Canvas (or PrusaSlicer with the P2PP plugin), it will give you two files:

1. .gcode for your V400
2. .mafx for your Palette

So, while the printer and Palette aren't able to communicate with each other, they both have instructions to keep them on the same page in regards to your print.

The guide I linked to at the top of this post explains everything in more detail. If you want further support in getting your Palette working with your V400, don't hesitate to get in touch with us at support@mosaicmfg.com!
