My machine continues to exist in what I’d call a “temporary” installation right now. The table is non-ideal, and I’m thinking of adjusting the size a bit, so a full rebuild is in my future.
That said, I was wondering if the wear I’m seeing on my conduit is normal. The picture below was taken a few minutes ago. I’ve been printing replacement parts on this machine. This is probably not a great idea, as a non-ideal machine is likely to produce non-ideal parts, but I wanted to get used to the operation and this seemed a good way to do it. With about half of the pieces printed, that means probably on the order of 50 hours of usage has produced these flat spots. There have been some filings on the surface around these, as you might expect.
