Additively manufactured shitpost

No one in particular: “Desktop 3d printing will revolutionize everything! We will have limitless access to rapid prototyping and production of vital parts where and when needed and the resulting advances in technology will be amazing!”

Really now?

Absolutely no one in particular: “But people will print untraceable weapons and… terror!!! aaaahh!”


Me: “heehee it’s a tiny Waffle House.”

scattered, smothered, chunked, capped, and PLA’d

So I made a bit of a silly mistake. I saw that Micro Swiss had this sexy new NG extruder for the Creality CR-10 and Ender 3, and I’d just bought this Geeetech A10M which had a COMPLETELY AWFUL extruder and hotend that had an incurable case of plasti-slobber that more or less made it incapable of skipping and resuming extrusion — retraction doesn’t even stop it AT ALL. I figured, hey, this would fit on the Geeetech too, right?

….the answer is, kind of, if you replace a LOT OF CRAP 😀

I do not recommend this if you’re not dedicated and/or kinda in need of a severe distraction from the trials and tribulations of the outside world like I am. Start with an Ender 3 instead if you want to get up and running on this sexy extruder system quickly. (As of when I wrote this the extruder is out of stock – I hope it’ll be back soon, because it’s SO NICE.)

So, what I found it needed:

* New belt. The belt comes up like 1/2 inch short.

this is a footlong not a bun length frank!

* New heater. Not only is the stock heater a weird size, but… it SUCKS!!! The stock heater is only 30 watts. I don’t understand why they did this but it explains why I was never able to get the thing to heat above 215C without timing out and Marlin screaming “Heeeeyyyy, I’m halting now and just wanted to let you know I might be on fire over here” at me. I replaced it with a 60 watt 24 volt heater which works just fine (don’t forget to PID tune again!)

* New fan. The shroud that comes with the Micro Swiss NG is sized for the 40mm fan on an Ender 3, but more importantly, the (20? 30?) mm sleeve bearing fans that come on the Geeetech are terrible. 😀
Amazingly, the print cooling fan which is a 4010 blower can stay – that is identical to what comes on the Ender 3 so it transfers over.
I spliced the wires on the fans to use the original JST plugs because they’re weird and I wanted to keep the neat little carriage board.

* Lots of random Metric screws!!

 

The original Geeetech mixing extruder is a hot sloppy soup sandwich of failure and it just had to go. This is what it looked like as I was disassembling it. Also, the “3dTouch” probe is a wobbly shaky mess with poor repeatability and has been replaced with a real BLTouch. Only buy the 3dTouch if you really really like having to mess with the Babystep Z function EVERY DAMN TIME you want to print something. Argh!

…also the default config for Marlin 2 on this mainboard does not enable babystep! WHY? Enable this!!! HHHHHHHHHHHHHHHHHHHHHHHHHHHHHHHH—-

And now……. the new, beautiful little extruder…..

Tool marks on the Micro Swiss

 

First off, I found it necessary to add washers and different length screws to secure the rollers to the carriage. The washers were needed because I guess the wheels Geeetech uses are thinner than the Ender’s wheels and the carriage scraped the rail.

The spacing of the mounting holes in the carriage board on the Geeetech are the same as the mounting holes in the stepper. I mounted it around the top of the stepper with a couple of longer screws and spacers. Please note the pinout of the probe – this is documented exactly nowhere by Geeetech aside from a very poorly made video. The pinout from left to right (facing the heater plug) is brown, red, orange, black, white. Also note that the heater wire fell out, it was not tightened correctly at the factory and I’m sure that helped that 30 watt heater warm up even faster! Uh, no.

Remove Before Yeet

So, the Micro Swiss is kinda cool but boy, can it ever develop extruder pressure – if you have the first layer too high, it will buckle *violently*, catch on the nozzle, and result in the print getting yeeted right off the bed!!! So, if you get lumps, bumps, buckling, waves, etc, STEP UP! I’m used to the behavior of cheaper Bowden extruders where the extruder doesn’t have reduction gears and will just skip steps when the pressure gets high, combined with the spring action of the filament in the Bowden tube – you can get away with having the first layer too tight and it will mostly print accompanied by thumping noises. This one will not let you get away with it, the print will get yeeted! 😀

Anyway, that’s dialed in and it’s printing a tiny Waffle House. Good times.

Now, as for that feline silliness: This is Gingy being all like “HOW ABSOLUTE DARE” over having to share her dish with a wild turkey. The turkey would be absolutely fine with sharing, but Gingy doesn’t trust him.

I’m pretty sure the nasty all in one would make the nice turquoise fade out to dead grass green, but I dunno. I have never let anything that foul touch my elegant rainbow.

¡Atencion! Esto es un post de mierda.

Yeah so now I know why nobody ever does the grid scrub / ESCIOT outgassing procedure on this thing– it makes it nigh fucking impossible

Yeah sure just leave it in standby while ramping up the grid voltage aaaaaand I’m just going to keep repeatedly kicking out into BG Heat and reducing the filament voltage to make your life interesting.

So yeah after I managed to get the dumb thing through the grid scrub and tried to put it back on air I experienced a very loud and through “oops I’m crowbarring and taking the whole plant down with me as I go” incident due to an arc in the tube at just 8 kilowatts output, it really isn’t ready to go back to work and is being a spicy little electron box.

Or, “Why I wanna replace the Carlson LongHaul radios”.

I’m basing the name of this post off incorrectly remembering this glorious scene from the Pop Team Epic anime and thinking it said long strokes, not  longs for good strokes, but whatever – I’m keeping it:

Ever just work with a piece of load-bearing hardware that is just asking for the sweet release of the e-waste bin? Yeah, that’s what half the entries on this page are about, but here’s one that, uh, yeah. The Carlson Wireless LongHaul… It’s still on their website as if it were a current product but upon calling their support engineer for assistance he told me what I had already come to suspect, it was abandonware from over a decade ago. The unit is a long range microwave radio designed to carry telephone traffic and look like a TDM (T1?) link, but also IP traffic, which is what we’re using it for.

So let’s check off the Boxes Of Decay:

  • Flash user interface
  • User interface via https with REVOKED SECURITY CERTIFICATE
  • Best I can tell— based on 802.11A wifi hardware
  • Cursed
  • Did I mention cursed

The only way to keep these things in service is to have an old version of Flash that hasn’t been expired via logic bomb – Ruffle won’t cut it as it doesn’t support Actionscript 3, though it handles http://aktiv-schaum.kg4cyx.net/ just fine. I’m sure you all missed those goofy Flash shitposts, right? I sure did. It also seems to play my old Fanimutations just fine.

I wish to state here that there are some dumb jokes in there that were very much a bad product of the time and I feel like they don’t age well, but not that I’d want to bury this entirely.

Anyway— on to the weird old hardware.

The board says “Avlia Networking Platform” on it and it looks like maybe an older version of this guy

The wifi card slotted into it is a Wistron-Neweb dual band radio, interestingly.. this unit only supports the 5.8 ghz side but some of the other ones we have in service, inexplicably, support both 2.4 and 5.8, consult your pineal gland

The serial and USB connections are unpopulated and I found no other way into the device…

Well, you can telnet in, but the user/password are unknown. It says it runs FreeBSD.

Finally by some sheer luck I found I had one old system with Flash on it and was able to set these creaky old things up. In the user interface (I can’t be arsed to take a screenshot) it has signal level readings which… uh, it’ll say it’s seeing -38dBm when the radio it’s connected to is unplugged and disconnected, and everything takes like four tries to get it to save and take effect and the Reboot button doesn’t work and

I’m so tired. I’m just so tired. can I just have a couple of Ubiquiti bullets and a nap? Please? Thank you. GAAAAAAABORAAAAAAAAAAAAAA
