ohh

2017-09-16 20:39:14 UTC  

so you put the heat bed output on the gate of the fet and wire that up to the power supply directly instead of putting all 20A of that through the pcb

2017-09-16 20:39:54 UTC  

not a problem. 20A Power supplies aren't hard to come by. What is the voltage required?

2017-09-16 20:40:08 UTC  

16A minimum, but honestly if you aren't putting 20A through that bed you aren't getting much use out of it for the plastics that it helps

2017-09-16 20:40:28 UTC  

depends, you have 12v and 24v pritners, most are 12v

2017-09-16 20:40:54 UTC  

Ah ok. Well shit, I have a ton of 12v 20A PSUs from laptops

2017-09-16 20:40:58 UTC  

all the beds can run on either and i would actually recommend getting a 24v supply to run the bed and maybe just give it its own controller instead of having the 3d printer control that

2017-09-16 20:41:10 UTC  

you'll get same power with less current

2017-09-16 20:41:48 UTC  

if you use a psu for just the heat bed, make _absolutely sure_ it can shit out absolute minimum 16A indefinitely, and you really want 20A

2017-09-16 20:42:00 UTC  

if you're gonna use it for the whole printer, 25A-30A

2017-09-16 20:42:05 UTC  

OK

2017-09-16 20:42:10 UTC  

a lot of people use gaymurr psus for this

2017-09-16 20:42:30 UTC  

Not all materials require a heatbed so. Maybe a separate PSU is in order

2017-09-16 20:42:34 UTC  

since they all have multiple super high current 12v rails and big chunky connectors meant to handle lots of current

2017-09-16 20:42:53 UTC  

most require a heat bed

2017-09-16 20:43:00 UTC  

you're limited to PLA and PVA without one

2017-09-16 20:43:07 UTC  

Yea, and PLA is shit

2017-09-16 20:43:24 UTC  

it's got pretty good wear resistance but for most applications i'd rather use abs or nylon, yeah

2017-09-16 20:44:06 UTC  

it's also got some surprisingly good chemical resistance, better than abs at least

2017-09-16 20:44:24 UTC  

gonna have a hard time attacking pla with any solvents normal people will have on hand

2017-09-16 20:44:54 UTC  

Acetone smooths out PLA if I remember right, the fumes at least

2017-09-16 20:45:01 UTC  

pla ighnores acetone

2017-09-16 20:45:05 UTC  

acetone smooths out abs though

2017-09-16 20:45:12 UTC  

Ok. My bad

2017-09-16 20:45:23 UTC  

well, ignores, if you let it soak in acetone it will very very slowly attack it

2017-09-16 20:45:35 UTC  

but you'll see it soften and delaminate, not dissolve smooth

2017-09-16 20:45:59 UTC  

it just kinda goes rubbery and the bonds between layers break

2017-09-16 20:46:17 UTC  

ah

2017-09-16 21:20:35 UTC  

On the waiting list for the delta.

2017-09-16 21:23:34 UTC  

what are some cool chink shit musical instruments

2017-09-16 21:24:31 UTC  

apart from melodica

2017-09-16 21:32:03 UTC  

how do you look at your recently viewed items on gearbest

2017-09-16 21:37:10 UTC  

i swear, sometimes i think i'm actually retarded

2017-09-16 21:39:31 UTC  

find it?

2017-09-16 21:40:25 UTC  

that's what i'm trying to do

2017-09-16 21:48:33 UTC  

history?

2017-09-16 21:56:55 UTC  

@aaaa you can get a decent ukulele for cheap

2017-09-16 22:00:38 UTC  

oh shoot good reminder i should get one

2017-09-16 22:00:58 UTC  

also kazoos

2017-09-16 22:01:42 UTC  

ukelele and kazoo so i can do bitches aint shit played at 300% speed
