Maybe you guys would be interested in a new project i'm involved in. Its name is Toolcat. Toolcat is a weekly curation of all things tools which means we're suggesting software which we think is great. We're also trying to help using this software. This is just a small start, we're already working on something bigger - so name it a an intro :)

Our website is http://toolc.at - maybe you want to subscribe to our free email service or to the OS X desktop notifications if you're not so much into email :)

We've also been featured on Product Hunt last week - maybe you want to share your love there: http://www.producthunt.com/posts/toolcat

Last but not least of course there's also a Google+ page that i just created - chime in here https://plus.google.com/u/0/b/116858572412109836471/116858572412109836471/posts

I'd love to hear your feedback - so get back to me here, on the page, on Twitter (@_toolcat) or... no, better not on Facebook :)
Ever wondered about what software to use for this or that or how to get that special thing done? Rely on the ToolCat, a weekly curation about all things tools. Free for life!

Hey community,

i just stepped in here and wonder how things are regarding metric units. So far i couldn't find any information about size of rubber tubing and other things. As everything is written in imperial units i guess these things may differ a bit from the metric system and from what we can source here in Europe.

The usual tubing for aquarium air pumps here is 4/6mm (inner/outer diameter). For what sizes are the printable parts made? From what I have seen so far the caps of water bottles (i have 1,5 liter ones) maybe identical (at least they're about an inch in diameter).

Any experience and suggestion for the metric system would be really welcome.

Thanks!

Would also be interest in your findings about sourcing of nutrients in Europe/ germany. Looking for an organic solution.

We have a similar problem with a cat and CO2 laser cutter.

Hey Android friends out there. As you probably know i'm primarily an Apple guy, but as i do some web/app development lately i was longer looking to get an Android Smartphone too to get some testing done and at least get to know how things work there. Of course i could have gone with a used/older one but i haven't so far. Today an invite for this One plus One thing dropped in and i'm thinking about pulling that option. 

This must be a good option to get a somehow sate-of-the-tech phone for a decent price, right? Any reason not to buy this piece of hardware for what i need it?

The only bigger downside of the one+one is a yellow tint in the screen but it shouldn't block your development process.
Another phone to check out is the Sony Xperia Z series. They are very powerful devices as well.

Has someone yet built a carriage for E3D and bed levelling? How do you guys do Bed levelling on your Eustathios Builds? Still finishing my outer frame but yet thinking about how to best do the carriag and auto bed levelling is a must have for me.

Highly valuable input, Eric. Thanks. I will definitely think that over. I terms of movable mass you're completely right. this is one of the main reasons I am building one of these printers. Whatever I do in the end it will only be good with the least possible mass.

Das "neue" Google Docs Interface ist wirklich grauenhaft. Usability völlig zerstört. Null Übersicht, völlig übertriebene Vereinfachung.

If you ever wanted to hear me praising an Android device - there's one of these rare chances now :-) (german language podcast, sorry english-only-speakers)

Bereits in der zweiten Folge haben wir mit ersten Ausfällen zu kämpfen. Weil Flo kurzfristig beurflich verhindert war, wurden aus drei die zwei aus der Geekwerkstatt.

Questions/Help  - 
 
How are your experiences with Taulman Bridge Nylon? I thought i could get it to print with critical parts on a cold glass covered with PVA but currently trying an iPhone 6 case which warps after 4-5 Layers at all 4 corners.

Any tips? +Richard Horne probably?

You gotta use glue (either PVA or glue stick) and you have to use a big brim. We typically will slice with a minimum 5mm brim, sometimes over 10mm. These same rules apply for 618 and 645. In our experience, Bridge will stick the best out of these 3 types of Taulman nylons.

Hey all,

just started planning my Eustathios-kinda build. It will be more like a re-planning of another printer (core-xy). I decided to switch due to some things that happened on the first prototype and that made me think it would be a better way to test this way out now.

Anyways. I'm planning to use 10mm rods outer and 8mm inner. I'm planning to with +igus Inc. Aluminum Rods and there RJUM-11-10 linear gliders. They are known to be not that tight than ball bearings (which of course don't fit here due to the rotation) and also not that tight than bronze bushings. Did anyone yet use them there? Are they good enough in this place?

I'm also not sure yet what to use on the inner. smaller rods. RJMP-01-08 probably won't be precise enough there. What do you guys think?

Here's a first "move around concept drawing" of the XY-plane. For everything else i will mostly reuse what has been build already for the other printer.

I'm using the +igus Inc.  plastic inserts at those locations... they work well as they're positively held in place by GT2 belts...slipstick isn't really a factor here. 

I used them in the carriage, and after a reasonable amount of bed-in time, had very little problems with them, but the carriage was a little larger than usual to give the igus bushings some rotational resistance. I've since changed to linear ball-bearings for the carriage, mostly because I had them on hand.

These "Here's a new machine that can do x and y and z and 3d printing" make me at least as tired as all the other "fantastic new style 3d printers" that launch on kickstarter each and every day. 

didn't 3d print for weeks now only because i'm tired of all that stuff - and all that makes me sad :(
