platform_texture and custom json file

[arhodiewithsoul 0]

Hi there,

 

I have been writing a custom json file for a printer and can get the build platform displaying (as an OBJ/STL), but the value "platform_texture" seems to be ignored, so my custom PNG is not displayed.

 

How is this implemented with the UM and Wanhao machines?

 

I have taken the liberty of attaching my working files - please don't try to slice and print just yet, they are still a work in progress.

 

many thanks

The mesh needs to have uv coordinates. The STL format does not support those, so you need to use OBJ. The OBJ file also needs to include normals, or the UV coordinates get ignored (if I remember correctly)

Well, that was a learning experience! Thanks for the nudge in the right direction ?. I can confirm that I imported the STL to Blender, followed this YouTube clip and exported to OBJ. The new file displays perfectly!
