What are you printing? I have a few 3d printers now and have got them where I can now trust them but it did take a while to get them well trained!

Hi Grant. Printing wise, nothing startlingly complex as I'm new to the 3d printing process. My son gave me a GeeeTech PRUSA I3 kit for Christmas a couple of years ago and I finally got around to building it and getting it working this year. I've just made a slide holder for a 500lines/mm diffraction transmission grating to fit between my mono QHY 5-11 camera and the extension tube. Seemed like the easiest way of making a low resolution spectrometer with stuff I had to hand. I  wanted to try out the grating in a converging beam (after the objective lens) and keeping all of the first order spectrum on the chip meant that the grating had to be close to it. This design was easy to make and in no way compromised the camera. 

If this works, many of my little projects don't, I will post an image or two.

I'm glad you've got your team of printers well trained. I'm still in the 'taming business'. There are so many ways to mess up a print and I seem to have found most of them.

Nice to hear from you.

Regards from George next the Sea.
