Please retweet if you want Labour, LibDems and Greens to cooperate at the next election in order to oust the Tories and introduce PR so that we never again have to endure a Tory Government with an eighty seat majority, obtained with only 43% of the popular vote.

@95point2 If you’re testing a particular sample of material you need the Beilstein test for chlorine. You are looking for PVC, which will release chlorine when cut by laser. You’ll need copper wire and flame to conduct the test.

@concreted0g @MearWolf COVID shut down delivery of a prototyping and fabrication module I was trying out. Just some fabLAB basics. Could do with a more serious follow up.

To our friends in the UK: please cherish, protect, & continue investing in your healthcare system! Once Big Pharma & special interests get their hands on it, it could take generations to regain. Millions of people in the US are fighting to have a system half as good as the NHS.

@m0untainpenguin @tetra3dprint @concreted0g I would guess the material is warping itself, especially if the shape is asymmetric. Not sure how you sort out the thermals so that it stays stable. Some stuff corrects as it goes over with next layers, but you've got those fine shapes more likely to show up the issue.
