This is a repost of what I have said over at r/SBCGaming ( https://www.reddit.com/r/SBCGaming/comments/1wgjehl/the_steam_frame_may_be_the_best_thing_to_happen/ ) ; Reddit has given me the 'suggestion' that it may be enjoyed over here at r/valve , but I feel that some preface for what I'm focusing on and why it is so relevant may help contextualize an otherwise strange segue -- SBCgaming focuses on retro gaming on single board computers, which often translates to phone processor SOCs being haphazardly shoved into a portable case in the cheapest arrangement possible by dozens of ti

TL//DR: Valve is putting a lot of effort behind getting a two generation old ARM phone processor to run modern Linux, x86 windows software under Linux, and android under Linux, all with open source software that will trickle into other devices.

This may be a bit counter-intuitive but I believe that the steam frame may be the best thing to happen to retro SBC portables; and not because of the VR. Also not, necessarily, from using the steam frame itself (though I have to personally admit 'laying in bed with a virtual screen projected into freespace to do retro-gaming has some appeal-- just perhaps not 1500 maplebucks of appeal).

The steam frame, due to its hardware selection, has encourage

With some of the newer dual screen, or just overall powerful, handhelds coming out- a lot of observation is being made about the input latency of the devices.

I am certainly not going to dispute some very good observations backed by measurable data, the latency exists, and it exceeds the original hardware, sometimes significantly.

However this is a problem that existed in the early days of emulation as well, and the solution was to tune in run-ahead for that specific system/emulator [1].

Is run-ahead not viable for these systems, am I missing some development (or lack of development) in the field of run ahead that made it not viable for addressing input lag?

So for those of you who are into both retrogaming AND 3d printing, but are not yet aware of the current contents on printables; be aware of the current contest to produce retro gameboy accessories. So far contest entries seem to vary widely enough from 'just the original game boy' that most retro gaming/SBCgaming seems applicable.

So, I am noticing a significant number of posts whose sole content is a youtube link.

I don't personally like this, if you can't take the time to actually provide a bit of a TL//DW for your video to tell people WHY they should spend time watching it, or explain why people SHOULD watch that video; I don't think you should be wasting SBCgaming's post stream space.

Possibly I'm wrong, people may like videos with no more description than a title of 'Taki reviews new portable'.

However if the community feels as I do, I will institute a rule that will prevent low body posts with a limit of around 400 100 words.

edit: I actually tried a 'what I think a good content video link would look li

UPS guy initially refused to pick up item, relented when I said 'no problem but I will be calling and saying you refused pickup'. Not sure if I should escalate this further or not.

I bought a chair from costco, it did not come with the seat mechanisim pictured, and instead had a cheap mechanism. Tried contacting the company, no go. Contacted costco, they did a return. I pointed out to the costco rep that full disassembly was not an option and that it would not be in the original box as a result- got the A-OK.

Chair is super-heavy; it was a UPS pickup from your doorstep.

Chairs involve multiple friction fit components that require a lot of effort (if possible at all) to take apart again,

BLUF:

Can a stepper motor be in a partially failed state where it starts skipping steps in only one direction of movement only after running for some time?

Is there another point of failure that would create a 'ratcheting' of skipped steps off of only one motor?

So, my printer has been working pretty solidly for a while, but is quite old.

It is now experiencing missed steps, but only along the A axis (Core XY; for people who only understand cartesian; only along the X axis, but not Y or Z).

It will print the first few layers without incident, but as of about 10mm off the plate it will start missing steps in the A axis, climbing -XY (but never +XY)

So I want to put together a 'advent calendar of 3d printing components', which means 24 components in total, hoping that I can get some advice on things to include- trying to focus on wear items that your generally going to be swapping out semi-regularly anyway;

Obvious:

• Nozzles
• Filament (probably just one roll as the big 'last day' item)
• bowden tube
• fans
• metric bolts and t-nuts
• bearings
• idlers
• hot end
• belt

What else, anything I'm missing, anything I should skip?

I have an old barn on my property in SE Ottawa (near amazon), it is not in great condition and I don't trust parts of it as a place to be inside, it is still upright, but has a bit of a lean on one side. It has a concrete foundation and floor, so the base at least is quite stable.

I'm looking for a contractor to stabilize the structure and make it safe as well as functional.

If you want to recommend anyone please do, if this is work that you personally would do feel free to PM me.

This feels silly, because I've had this printer for years and run something like 20kg through it just accepting that it was never quite 'spot on'.

However I just really had a realization that adjusting the x/y steps does not actually account for differences in step distance, and instead is likely resulting in some skewed prints (I've now done a significant amount of other upgrades which have removed various other 'build noise' inherit in the printer (ender-4)).

For core-xy you 'configure' this by varying belt tension (and thus the effective steps/mm), then you calibrate x/y in software normally[1].

However- since its H-bot and not core-xy I realize I have no idea how I'm supposed to acc

Before I begin, this is a Dan Savage letter. For those who don't know he is a sex advice columnist, and he rightly looked at this letter and recognized the madness of the writer, not quite calling her out, but calling her out. It is old letter originally posted in 2014, but it was reposted in August which is when I encountered it and when I was reading it I just though to myself 'this is a crazy Karen, but the letter is from HER perspective!'. It comes complete with a Karen who:

1. Throws tantrums and thinks this is OK.
2. Engages in regular violent activities to the point where her husband's family is terrified to have her at events.
3. Punches her husband.
4. Goes and hides in a random

TL//DR- What board/software/etc should I get for my 3d printer to enable the use of a dual extruder?

​

So I have an ender-4, admined by an octopi system, after some significant upgrading to the stiffness of the frame, and the H-bot mechanism it now prints GREAT (as in I do regular printing challenges with my buddy who has a pursa I3 pro and I generally win them). I don't make enough use of the laser engraver, but its there. I am still using the stock ender-4 firmwear.

​

I have a few projects that I would really like to do in multiple colours, stopping the print part way and changing the colour is possible, but annoying.

I don't believe the ender-4 b
