I've been 3D-printing for around five and a half years. So I'm not a rookie, but I just made a #rookie #mistake.

I've spent the last couple of weeks making compartments and dividers and such for the toolboxes I take to the Repair Cafe. Lots of test #prints to check fits and footprints, full prints, changes to design based on lessons learned during use at the last cafe, etc. I've put around three kilograms of #filament through my printer in that time.

Then, in the last couple days, I started having various problems. At first they only showed up on big prints - #adhesion and #curling, which I've had before when pushing the limits of my bed size. But prints seemed to be getting #sloppier, and I had a couple of spaghetti explosions.

Tonight, I finally took the #hotend apart and looked at it closely - it's very difficult to do when the printer is fully assembled, because it's a #delta printer.

Lo and behold, the nozzle appeared worn. And that can account for all the problems.

I should have checked this sooner - but I've only been printing plain #PLA, nothing abrasive, so I didn't think of it. Lesson learned.

Pardon the shitty photo from a cheap digital magnifier. The old #nozzle #orifice is about 1.5x the diameter of the new one - so 2.25x the area. No wonder plastic was going everywhere but where it should go!

Seems to be printing *much* better with a new nozzle.

On May 19 we have Pim Elshoff talking about: Filament vs Inertia, and other bad ways to make UX decisions

We have:
- A place to meet other like-minded people
- Free food (pizza, including vegan) and drinks provided by Suma Eindhoven
- A @jetbrains license to raffle

Dave Randolph, creator of PrintedSolid has resigned from its CEO position and departed. Prusa is now taking the lead.

Dave, if you read here, thank you very much for all the great and hard work. Thank you for having trusted my project and sold many Bear frame kits. I wish you all the best for the next steps 💫

Full disk solar image from a week ago.

Was a spectacular clear day but somewhat compromised by smoke from north western Canada (I'm on the far east coast!).

Some #prominences are faintly visible. My solar processing still needs work :=)

#Autostakkert, #IMPPG and #GIMP for processing and colourization. 70% of 1000 frames stacked.

Thank you so much #GratKit for these beautiful filaments 😍
I've always wanted to have these kind of pastel colors to use for my designs and finally I got them 😍
Which one is your favorite?
I just love all of them way too much 😍
