The airbrush cleaning is almost done - two fully cleaned and re-assembled, one with a few bits that still need cleaning. I might need to replace the needle in my 0.3mm smaller one - I think I must have hit the tip with something.

On the 3D prinitng front, I seem to have resolved the big problem I was having. It seems the cause was a combination of vibrations (reduced by using foam inserts from figure trays under the feet; also by tightening up some of the bolts on the printer's frame) and a couple of settings in the slicer software.

I spotted this afternoon that my first filament spool was running low so I printed a few batches of small items that I'm going to need for a big project. I had just enough for that:

After removing the remaining filament, I did a little bit of maintenance on the printer, then loaded up a new spool of filament - I went with purple. The first job was to run a couple of quick calibration tests, and settings test that I'd forgotten to do on Monday:

Supports test after removing supports

It seems that I have got my support settings dialed in just about right. The supports came away easily enough with pliers and left clean surfaces with no evidence of sagging.

Yesterday I ran a test-print of a part for the big project I mentioned further up:

There were a couple of issues with it - the problem I mentioned above and also that the "bridging" over the recess was a bit messy. I've found a slicer setting that should resolve the latter and will test that tomorrow - if that doesn't work, I'll just have to add supports for the bridge.
