I’m just curious how you set up the hardware,
I’m using a buck converter and a 30a relay
Probably a 40mm fan, unless I don’t need it
Plus a pi 3 a buddy gave me for free
Torn on which enclosure I want,
Full front coverage on the right
Back by the psu
Or a bit of both
I’m a bit confused, what are you planning to use the relay for?
In between mainboard and psu
Had a close call with what I thought was a failed mosfet recently… turns out it wasn’t
But it a bad taste in my mouth about not being able to stop that type of thermal runaway
Learned that octoprint has a power control plugin that lets you manually or based on temp kill the printer
As far as the 30, 15 would be just what I need but can’t find a 15a 5v controlled relay
Ah, makes sense. Haven’t used that plugin before, but it’s definitely a good idea (I’ve had some close calls with thermal runaway on my other printers).
A fan isn’t a bad idea, but I don’t think it’s necessary in my opinion (although a lot of people disagree with me). I’ve used Pis for years, and never had issues. Octopi will alert you if the Pi is overheating or undervolted, I wouldn’t worry about it.
Obviously this is different if you fully enclose it in a box without any ventilation at all, but it should be fine in pretty much any other enclosure.
My solution is pretty much as simple as you can get tbh, I don’t have an enclosure or anything. My Pi 4 is just flopping around, powered with a USB-PD phone charger, plugged into the Ender 3 pro with a micro USB cable (the one I got with my proxmark, actually). I’ve got some tiny heatsinks on the Pi, since they came with my Pi 4, but I’ve never used heat sinks with my other Pis.
I also hooked it up to ethernet, since I had already run a cable over by my printer a few months ago, but it’s just a nice to have kind of thing.
I’ve used octoprint via wifi for years without connectivity issues. If you use the official raspberry pi imaging tool, it’s super simple, you set up SSID and password when you write the image to a micro SD card.
I’m not too worried about the PI needed a fan, but the buck converter I’ve heard back and forth on its toastyness
Are you using a buck converter so you can easily pull power from the printer PSU? I guess that makes sense, since you want to mount it to the PSU in an enclosure.
Is the buck converter specifically for the Pi? In my experience, Pis can be extremely finicky about what power supply they use. It also needs 2.5 amps, rather than the standard 1 or 2.1 amps in most power supplies. That’s why I try to use official power supplies when I can, I’ve had too much frustration with undervoltages.
At least 3 amp, and adjustable voltage
Actually have 2 to choose from on hand
Note that the first one you linked mentions:
“need to add heat sink if the current exceeds 2A(output above 10W)”
Yep I saw, kinda torn between the 2,
The one is a bit overkill, the others about at its limit
But think I’m leaning the big boy, mostly for easier connections with the screwjacks lol
But it will require altering the enclosures I want to use…ugh
A heavily modified ender 3
I stripped the heatbreak grub screw… essentially ruining a microswiss hotend :-/
It wasn’t a quick and hasty strip but a little here and there… I kept having heatbreak leaks, so I kept trying to tighten things up more and more, and small threads on soft aluminum… well…
Already replaced and printing again,
Just need to calibrate to the fresh nozzle a bit…
I think the new microswiss .4s are actually more like a .35…. In the begging a .35 line width was perfect… but after 3 years of wear… a .4 was dialed in just right (they wear very nicely)
Well I decided “fuck it” nothing else was more important than anything else… so I started a print…
8hours and I’ll have an idea how good that case is
I’ll probably reprint in either orange or black later but I didn’t feel like swapping filament
Same printer here, also heavily flavored 
I had lots of problems with heat creep (specially when it went above 85-90f ambient), and ended up upgrading the cooling fan and going to a titanium heat break, some of the best investment I’ve made on the printer …
Fellow printer peeps,
I’m looking to get into resin
I’ve been back and forth and all around on fumes and Vocs and whatnot
Internet is back and forth between “you gun die” and “it doesn’t matter” … Im mostly concerned because I’ve read some intermittent reports of harming fury friends easier given smaller size
I know smell doesn’t equate to safety, which is important given newer resins smelling better but may or may not be any safer
I have a office with a closet just big enough for a small table to put a resin printer on,
Im considering putting a small bathroom ceiling fan in that closet… thoughts?
Alternatively I could just get a carbon air filter or something?
ewwww, its really sticky, and probably not great for your skin.
Resin is fantastic, the smell, although not great is also not offensive (its quite mild)
Who knows what the long term effects will be, definitely put in some ventilation, and filtered if you can.
Do forget you will need a wash station and curing oven for the best setup, so plan your space accordingly.
drippy drippy, sticky sticky, washy washy.
Its not the cleanest of options, but you can’t beat a good resin option, actually SLS is awesome too.
You probably already know, one of the best pros for resin is the print times are similar FDM, until you start printing multiples, then Resin SLA surpasses FDM.
Blah blah, other examples, pros cons etc
Mainly I want to get into resin for the accuracy and small part structure that fdm can manage
Minis or things with ultra fiddly supported structures
Actual clear or translucent prints also sounds epic
as long as you’re talking about venting to the outside of the home / building then great… but not like “venting into the main room” or “venting into the attic space”… if you properly ventilate the space and can close the closet door during printing, then concerns about VOCs are basically moot. If you do vent the closet and use the door as an air block, put a small passive vent / hole in the bottom of the door so the air flows in and up and out.
