Anet A8 to AM8 Conversion

A little backstory…

I’m pretty sure it was in 2018 that godoloju got me an Anet A8 3D printer for my birthday/Xmas.  Nice guy huh!  It took roughly 8 hours to get it put together and printing my first print.  V1.0.

At the time, these were kinda known to start fires.  The connection on the bed would sometimes short, and on an even more rare occasion, throw a spark.  But it was a thing.

Not wanting to burn down my house, I quickly did some research into different solutions and went about getting them installed.  I printed cable chains, belt adjusters, and frame reinforcements. I bought mosfets, a higher quality power supply, and a plug/switch combo..  Just to make it a bit more, well.. more. (the volt meter is just for shits and giggles)  I once estimated it at roughly 200 hours worth of work, and pushing 1000 hours if you include all of the print time.

Then, there was the VR incident of 2019.

I had set my VR up before getting the printer.  The printer ended up in the ‘play zone’ for the VR.  Then, I was letting a particularly long friend experience VR for the first time.  While violently throwing a robots head at another robot, my friend managed to hook and throw my 3D printer across the room. 

The acrylic frame exploded.  

I couldn’t look at it for a while.  

About 6 months ago, I set about adding the metal frame, or the AM8 conversion.  Same printer, but extruded aluminum frame.  I used as many parts from the V1.0 as possible, but I did replace the thread rods and the X guide rods. 

The original bearings from the Anet A8 kit had been wearing grooves into the guide rods.  After a bit of research, many we’re recommending these plastic ‘sliders’ (not sure what else to call them).  I’ll update this sometime in the future and give some type of review of them.  But after 50ish hours with them installed, they seem to be working great.

Manual leveling is just tedious enough that it was pissing me off.  It seemed to fluctuate some between every print.  I do remember at one point I went like 8 prints without needing to re-do the leveling.  So, one of the other goals at this point was to get auto bed leveling working.  I had purchased a capacitive and inductive sensors, and had planned on using the capacitive as it was supposed to work with glass.  However, I was finding information on several different ways that it needed to be connected. One of which required a daughter board.  I ended going with the inductive because it’s setup was basically plug and play.

Well… there isn’t a ton of configuration you have to do for the sensor itself. You do have to enable and configure auto bed leveling in the firmware and get the sensor mounted in just the right spot.  There are guide out there suggesting a ‘correct way’ of getting your hotend and sensor aligned properly.  I started this way, but ended up making a type of jig.  Allowing me to put the tip of the hotend in the correct place, and then set the jig under the sensor, and then tightening it up.  I’ve used this method twice now, with success.

Nest history > 10 days

I like data. I’ve always been a bit of a data junky.  In my personal life, I’ve found looking at the data is usually interesting but not terribly useful.  But at work, I identify issues all of the time just by keeping different data up on my dashboards.    This write up however, is for my home, and my new Nest thermostat.  I was so excited to get this thing, I was curious about a dozen different aspects of these smart thermostats.  However, I was terribly disappointed when I got it installed and working and realized that the Nest only stores the last 10 days worth of data.  My assumption is they keep all the data (doesn’t everybody?) but for speed purposes they only let the customer access the last 10 days.  Whatever, its frustrating, but its not like their going to change it for little old me.

Imagine my surprise when I discovered they have an API that the customer can access. I had been bitching about the fact that Nest doesn’t give the customer access to this data, like on the website or something.. somewhere at least.  About 3 weeks later my buddy Buddah sends me this link that I guess showed up on his FaceBalls.

… I may have gotten a lil chub from this.

DEFCON!!!

So the way I figure it, there are three types of people that come to my site. Lovers and Ex-Lovers, Friends, and Them. For those of you who don’t know, Them refers to that secret society of the illuminati that are desperately trying to ruin my life. I know what your thinking, your thinking “Paranoid Freak”, or “Complete, COMPLETE MORON”. But I tell you its true. Their out there. I see them peering into my windows when I am masterbating. Oh, yeah, I forgot to mention that Them have some sort of sick twisted fantasy with me, neked, on the couch (that ya stick too when ya be’s neked on it) watching some young gob guzzulin mulitiple penetration hoe get it from 6 angles. Yes, I said six. I gots the good porn.

So, did ya get a mental image of me jerkin my shit? Did ya now that I told ya too? Told ya, you might as well call me daddy.

DefCon 12 starts TOMMORROW!!! Mat and I are headed down tonight, gonna get there as the sun rises and start the partin. And then around 2ish we pick up Davey McChode from the airport, and he starts the partin’ with us, around 3-3:30ish we get to check into the hotel…. prolly get a couple hrs of much needed sleep and then GEEK.

The amount of geekin’ will be gargantuan. Children will cry. Angels will fall. Devils will quit poking people. Strippers will loose MONEY!!! Chad will find his penis!!!!

Sometime Friday night Stan shows. This is when I am assuming the party should really get started. By then we should have the camcorder set up, the parabolic dish slowly mircowaving the neighbors and our own power circuit and OC-48 pulled into the hotel room.

I am guessing we’ll have about 10 computers. 1 camcorder. 3 digital cameras. 1 webcam (which i am going to try real hard to get setup asap). And four sexually frusterated broke guys in a hotel room. Admit it, your jealous.

Goals For DefCon:

– Come Home Alive

– Finish Slimserv.com

– Get something solid up for DeviantSociety

– Get Kelly’s PC working Correctly

– Win 37.5Million Dollars at the craps table (the .5 is for the rest of you, so that we dont have to listen to you whine)

– Leave Vegas without warrents

– Get my ass licked.

– Make it home with a $35 hooker tied in the trunk. (see, the trick on this one is actually getting home)

– Finish getting the server ready to take customers.

– Enjoy the fuck outta DefCon

I will try to throw up updates randomly throughout the week. Keep ya’ll updated. And then at the end of the week we will take a look at the goals and see what we did and did not accomplish.
