A Tea between friends :-) How was Your Day

Going to a John Williams concert with R2D2 IS holidays times 1000 imho...

[ivan.akapulko]

I'm finding the days go quickly as I prepare for a 3-day John WIlliams Concert this weekend. This is the 3rd time I have been asked to participate in their show and a majority of the soundtracks being played will be from Star Wars. I love being involved with the symphony orchestra (90 piece!) and asked to provide R2-D2 to be on stage. Of course, I have nightmares of remote controls and receivers failing...which has never happened...but still, you try to prepare for the worst! The shows are in Portland (Maine) which is 2 hours south of me.

One of these days, all of these travels should be for a vacation

This should be great news! Will there be a live broadcast from inside R2D2? Fingers crossed!

Sciense 2.0 channel make a great series about the longest expedition into orbit. A year on the ISS! There are subtitles in English.

It could be worse, you could be inside the R2D2

My goodness you guys got quiet!

[nilrog]

We are so overwhelmed by the force

[jonnybischof]

Very busy time (then again, when am I not busy...).
I've been working hard on my 3D printer electronics platform. Some polish here and there in the schematics, and I still have to complete the layouts for the two main boards, but I will be done with a first prototype soon-ish.

I eventually got a dial indicator and played a bit with it...


Need to design an holder for the hotend to use for the bed leveling

[reibuehl]

How about this one: https://www.youmagine.com/designs/dial- ... ltimaker-2 ?

[Amedee]

That won't work for me as I need to hold it under the clock, but that gives me an idea on how to start!
I was initially thinking of something at the base of the of the hotend, but it is definitely easier to start from the top.
Tnx for the link.

Had a 'Nylon' week-end

[LePaul]

That looks great!

There's a few pieces I would like to use nylon for with R2...especially for pieces that move with actuators and ballscrews (like the lift mechanisms)

[Amedee]

It is indeed an interesting material. When applying forces it will flex rather than break which makes it quite strong.
As bonus, it has a very nice finish.

Only downside I see is that it has a relatively low Tg (52°C from Taulman's data sheet), so it is not a very good candidate to operate in hot environments...

[Izzy]

LePaul, what about the material from Igus, I was going to try it again this week with the ruby nozzle, if you can print at the high ABS temperature it is good for bearings
