    They can only exist in major cities where people like us, who read, live.

I give you a unicorn

There are seven independent new book stores in Kansas.

Thanks! I don't really know what I'm doing.

    What's your use goal? I'm not sure what units you've used, but there's a definitely a visible difference between the Delta printers it looks like you're tooling around with and, say, a 3D45. Not that there's anything wrong with that, especially considering price point - I'm just curious what your usage is.

I was thinking of the sort of middle to lower tier builds I see on where people are building for hobbiest or home use, and running $15 rolls of PLA through it.

Right now, I have a secondhand i3 clone with a cracked acrylic frame, worn out bushings, and zip-tie secured linear rails. Objectively, it is a steaming pile but it works ok. The belt pulleys on it don't even have bearings, they just rotate on a screw. The z axis lead screws wobble all over the place. On the one hand, improving on it should be pretty easy. On the other hand,the thing already is capable of producing reliable interfaces for my camera's lens mount and hood rings.

I'm still figuring out the best workflow for designing stuff. I've gravitated to mocking the whole thing up roughly in blender, and then fiddling in openscad until it works like mockup.

We had an ice storm yesterday, and I realized that I do, in fact, have smooth rods. They're just tied up in my acrylic framed printer.

I actually have a fair amount of them, so I was able to work off of this design:

And thus, the product of yesterday:

Currently, it seems to have a build area of ~180x180mm, which is horribly offset (the orange square). The constraint is that moving the smooth rails outwards causes the pulleys for the drive line to collide with the frame. Fixing that is easy, but fixing it in a way that doesn't add a huge amount of volume (and print time) to the corner pieces is still elusive for me.

I'm discovering I kinda like doing CAD stuff so long as I'm using OpenSCAD. FreeCAD is easy to use, but I never learned to use it in a way that didn't screw you over if you needed to go back and change something you did at the beginning.

For new books,

My local bookstore of choice sounds similar. Lots of author events, patrons can place review slips on the shelf under their favorite book, two cats, specializes in mystery and politics but will buy whatever.

My second favorite bookstore is mainly a leftist-activist art gallery / stationary store that stocks verso books and publishes local pamphlets and stuff.

In the past 10 years, I've bought maaaaaybe $12 worth of stuff from BN that wasn't last minute gift shopping. Usually I wandered around and then left empty handed. I spent probably $250 between the two local shops last year.

    They have to offer something that a website can't: people. That requires investment in your staff, the community and building more people reading books.

The community part of this is key for any sort of small, independent business anymore. You can't get away with simply being the only place in town that has $ITEM, because amazon definitely has $ITEM for cheaper.

The owner of our independent hardware store passed away recently. I've heard a fair amount of talk about how one of the various local non-profits should step in and buy the place if his family decides to close shop.

I'd absolutely throw them some money to do that. It is a community space just as much as it was a business. Probably more the former than the latter, as Rod would regularly knock down prices when writing out the receipt just because he felt like it. And then you could mill about talking politics/sports/homebrew for however long you liked.

    Whoever decided these were the golden years should be strung up by the ears.

    -- Rod Ernst

Get the community part right, and I'll pay you a good deal more than I'd be willing to pay elsewhere.

Both of the singles I've heard for their new album have been very good.

Printer progress. Design is a little weird since I'm working around the aluminum extrusion I'd already bought. Smooth rods would make more sense. Should work though.

Pink bits still need work to mount the motors, which will probably need to be inverted. I also need to throw together the bushings.

Green bits are ready for test printing.

Screw count for the x/y bits seen here should be a maximum of 14: 3x per motor to mount the drive spools from Richrap's sli3dr printer linked above, and 4x per motor to attach to the frame.

The dollo printer bits I'm using as a library have worked well in the small test pieces I've made.

    Highway bus lanes are generally on the right over here.

Here in KC, the bus lanes are actually in the marginal "shoulder" area to the right of the actual road.

I know High Occupancy Vehicle lanes are to the left in the Dallas Fortworth area, though.

We're improvising all of this I think.

I'm late to pubski.

3D Printers

My delta 3d printer project stalled out in November. I've printed everything I need to finish it, but I haven't bought the "vitamins"; i.e. all the fasteners and such. I liked designing the bits that I did, but the idea of building wasn't so exciting. Today, I started designing a new printer based on a really old cable layout. My goal is to use as little fasteners as possible without compromising quality.

We will see how I do. My bet is that most printers are vastly overbuilt in the name of precision that won't really be visible anyways after the sloppy process of spitting out molten plastic.


My old boss was actively trying to fire me. Well, not just me but all of my family that worked there. He wasn't competent enough to actually pull it off, but the effort was there. The best he managed was an offence I could have gone to the Department of Labor for and gotten him shitcanned, and teaching me that management can't produce a written copy of the attendance policy.

My new boss? He keeps telling me what a good job I'm doing. He's calm. He's respectful. It is fucking weird. I'm so use to being in combat with management. It's weird.

Everyone here will place emphasis on different parts of that blurb, though.

Some people balance out the whole thing equally. Others value the 'civil' and 'insightful' bits with different weights. Each has their own interpretation of what those terms actually mean.

People will rub each other the wrong way from time to time.

Instead of down votes, you'll find moderation tools for each user on the left hand side their profile page.

You'll also find filter links at the top of the feed pages for tags and webdomains.

You can use these features heavily, or not at all. It depends on what you want.

    The Duluth commercials make me retch. Is the clothing any good at all or is it just a brand?

They brand themselves as workwear... and for that purpose it is mostly just branding.

The weave on the FireFlex stuff is pretty tight and holds up ok, but the flexy shirts I have shed buttons like crazy and the plain ol' pants material is much looser woven than Carhartt or Roundhouse. The DWR coating lasts as long as any other, definitely not a lifetime thing.

I really like the cut of their stuff, it allows for lots of movement. But my stock is getting replaced with Carhartt or Roundhouse as attrition grinds ever onward.

Brought up the fact that the memo said there were Three FISA court renewals with my Trump supporting facebook friend.

I asked what the evidence uncovered by the FISA warrant must have been for a judge to renew the warrant three times.

He said: none, it's politically motivated.

I asked if he had that little confidence in Chief Justice John Roberts, the Republican who appointed the FISA judges.

And then the conversation stopped. Weird.

edit: Ok, he apparently he doesn't trust politicians, but he never said Roberts was one. Won't comment on Roberts, but the FISA court has people who hate Trump, and there are activist judges that need to be removed from duty. Brought up the travel ban. Won't comment if this means that the judiciary as laid out in the constitution is fundamentally flawed.

There's more, other people are interjecting now, but I'm done. I don't want to piss him off: he's really an ok guy and also our good sniper in Halo.

I'd like to nominate the Cerner campus as a replacement Kansas pick. We've got toooooons of abandoned spaces here, the one they went with is nothing special.
