Ah well…there’s a story…I spent and absolute age colouring in the model using 3d builder (the tools that ships with Windows 10). I exported into Canvas3D for it to only ignore all my hard work. So using Canvas 3D the tools are not as intelligent as 3D Builder (IMHO) but I was able to assign the colours to the model, which is pretty simple. Its a case of picking / tagging the surface 1 to 4 which is the feeds on the surface. I’ll upload some example videos linking to my workflow in a few days if its any use to others.
That said its started to print the splices and its safe to say I need to keep calibrating…
