Today, I 3d printed a bunch of parts that I will later machine out of aluminium. I also placed the order for t-nuts and will probably order the extrusions tonight or tomorrow. I’m having a bit of an issue with the rails supplier (china) due to holidays there. Worst case, I’ll find another supplier!
I set my 3D printer to the fastest print / lowest quality (0.35mm / layer, 120mm/s) as these parts will be discarded anyway. I also had a ‘spaghetti’ incident where one of the supporting rods for the head disconnected (magnetic) and the head simply sprouted plastic in the air.
