I was awake long before dawn and popped together a quick or not so quick HowTo. It was requested by MARK. He has a posh new printer and needs slices. I was more than a little surprised to find the first trial run with Blender 2.79b worked or was close to working. 2.80 Beta said no.Here is how to do it roughly…..Very roughly.The rest of the day was spent changing a couple of tractor tyres and that is a real mauling sort of job. It requires a different skill set and a bit of sweat. Nothing like variety to make life interesting.Have a good weekend.
