Connectors on the board should be moving <10A since it's a 24V printer, it should be OK.
Eh, I already made the enclosure and mounted everything up with good quality 12 ga. copper wire and 20 ga. signal wire. It's back to makin' dildos.

Take a pic of the bottom of the board... one fuckup that Anet did was putting thermal relief on the connector pins to make them easier to solder, wondering if Creality did the same thing. If they did, scratch back the solder mask beyond the thermal relief and put some big blobs of solder on there to provide a thermal path for the pins.

... and of course they fucked that part up.

Passed a "tell creality to fix that too" suggestion along to /u/sexycyborg.
FYI, the soldered wires there were for my ghetto daughterboard MOSFET addition. I gave up on that one, it's in a static bag in a box now, and I got a spare that I flashed and installed yesterday.

Wait, that's that chick on Reddit that makes super nerdy light up costumes isn't it?

Yup, she's also the "community liason" for Creality. Several months back she convinced them to obey the GPL and release their Marlin firmware implementation. She's got a good bit of pull with them from the sounds of it.

I made a comment on a /r/3dprinting discussion and mentioned Jehannum's exploding FET and the lack of inductive clamping on the board... she spotted it and replied "I'll forward this to Creality's engineering team" - bitta back and forth after that, and now I'm hoping Creality's next version of the control board will be much better.

Designed this in the YYT departure lounge earlier. I've got like 5 different bong designs now, and one of the halifax bong shops is gonna buy them from me. Fuck ornaments, I'm in the drug paraphernalia business now!

Picking up a few more PLA colors tomorrow, gonna make half a dozen.

Total list of bongs: planet blaster, princess bong, pokeybong, magic eight ball, and now the Pot Flite.

@kiwi I still owe you a 2 piece bong design you can run off on the Select Mini :) I'll get it done eventually.

I gave my brother one of them for christmas, so I'm a bit more motivated now.

So one of my co-workers bought a MP Select Mini V2 at an auction for dirt cheap, he's been playing with it non-stop for the past week and now he says "I wanna bigger printer that doesn't suck". His budget is $500 CAD.

Looking at building one from scratch for him. Basing it on a combination of the Haribo Mod 3030 clone (where you take parts off a genuine Prusa MK2 printer and put them on an aluminum extrusion frame), and Thomas Sanlanderer's dirt cheap MK2 clone "Dolly". Expensive where it should be, cheaped out where it doesn't matter.

Good parts:
Misumi framing, precision ground rods and linear bearings.
Good quality belts/pulleys (probably from Misumi too)
Genuine Mean Well 24V power supply
McMaster-Carr PEI sheet for the heated bed

Aliexpress parts:
MK52 heated bed and spring steel sheets
Electronics, steppers, lead screws
Everything on the hot end.

End result will be pretty close to my printer, but with a Prusa MK2 extruder instead of the Titan Aero clone that I've got on mine, and a 3030 frame instead of a 2040 one.

... and now that we're making a Misumi order, I'm costing the bits to build a 2nd printer. The Hypercube Evolution looks pretty interesting,

And in other news, I'm looking at getting a 2nd printer for bongmaking (yay)

I want a moving XY gantry and a solid frame so I can print tall shit quicker, and kinda want 2 colors... and someone on kijiji is selling a Makerbot clone with dual extruders for dirt cheap. Only problem is the build area sucks. But that's easily fixed by re-framing the printer:

Messaged them, haven't heard back yet, but this is probably gonna be the way I'll do it.

I'm officially in the bong business. Got a cheque from a bong shop today :)

Bought the Makerbot clone for $250 CAD. Owned by a teenager who didn't know what to do with it, kept running into problems and trying to fix them. Makerbots are the quintessential "in the corner of a high school library, sitting there broken" printer, so this was pretty much the same situation.

Needs some work, but not too much work.

There are literally two shelving units in the 3D printing lab stacked high with disassembled Makerbots
After working on both printers now... holy fuck Ultimakers are so much better built than this crap. I bought this printer knowing full well it's cheap and I'm planning on replacing a good part of it, but it's an *exact* clone of a Makerbot. Everything I'm looking at and thinking "yeah, that's shitty" can be found in exact form in the Makerbot files.

I'm thinking I'll change my mind, get this thing going again proper and resell it, instead of giving it the full makeover.

edit: are they disposing of them at any point? Lots of good parts to be had - steppers etc.
