Well, the added weight to the Z carriage seems to have reduced the oscillations a bit which is great.
I am a bit under the gun for our next race outing in October, so looked to outsource some of the fairing parts. So far, 4 out of 4 vendors have refused a quote as the parts are too thin and difficult! They all recommended sectioning them into multiple pieces and gluing together. When I said that the parts have been printed successfully multiple times in one piece on a home built printer, they were very surprised.
On one hand those responses were pretty disappointing. I was expecting that industrial printers would be a step above what I hacked together. They are not. On the other hand it speaks volumes to the quality of product that Duet3D sells and the support from them and other users that is provided on this forum. Many thanks to everyone that has chimed in along the way, @dc42 and @mrehorstdmd in particular.
I've also recently printed a few big, chunky parts that came out excellent with none of the artifacts the tall, thin fairing parts have. I guess I will focus more on bracing for the fairing parts to keep them from shaking during printing. Maybe more retracts will help too. I do notice a little noise when it is doing the infill, which is assume is the printhead hitting slightly high areas of the previous layer. I am also having some issues with the fill areas on the first couple of layers looking really fuzzy, which I think is over extrusion, but I reduce the flow down to about 70% and it looks the same. The parts come out fine and I am still time constrained, so am kicking that can well down the road.
This is a pattern for a carbon fiber gas tank. Printed in two halves and glued together. About 3.5 gallon capacity. There was a slight bit of the print rising up from the build plate, but nothing major and easily taken care of when it is sanded and bondo'd to get a good surface finish to take a mold from. Also doing a mold for a bellypan that is coming out just as good.
