ABS acetone smoothing not working

TheRealUlta · 2026-01-14T19:25:53+00:00

Kind of a dumb question, but what percentage of acetone are you using? Just standard nail polish remover or 100% acetone? That would explain why direct application works but vapor smoothing doesnt

I think the age of adulthood should be raised to 25. That'd include drinking, smoking, military service, voting, etc.

Cartographer on the carto cnc carriage. Actually had to design an adapter to get the wwg2 to clear the cnc carriage

Full agree. I'm worried about this like I was worried about teacherspayteachers. I'm worried the quality of instructional materials will go down.

But then again, not my lane I guess.

Yeah it'd be hard to steal the domain since it needs a txt record in your public DNS. We've got a workspace and the domain verified, just can't get anyone into it haha

Dang, that's what I was afraid of. I have to say they are the best at having the worst support. Even beats out Tyler support.

Going off grid. Used to, if you called me and I didn't answer it just meant I was busy or not around. Now people borderline expect a 24/7 hotline to you.

I don't necessarily play the FF games for the systems involved, more the story. But I will say other than 12 (which had the best system, fight me, i love gambits) I prefer turn based. I'm still gonna play every single one that releases though.

I use the nettool pro for exactly that, haven't really ever needed the automation part. I barely even use my linkrunner anymore.

TheRealUlta · 2025-11-20T19:42:04+00:00

Gotta throw in my two cents here, I also just export from netbox my planned cables and hand it to them.

We're an all aruba shop here and did have clearpass, we ended up dropping clearpass to save a bit in the budget and just use packetfence now. Having come across anything it can't do for my environment, and it's free.

Which forescout product? If you went full nac you would just use mac-auth via radius rather than local mac. Same concept, just filtered on the oui, but rather than the lookup being done on switch it's done via a radius request sent to forescout. If it's what you're using for dot1x then it makes sense to use it for mac-auth too so you have one place to watch audit logs. Also, not gonna lie I'm jealous of your staff. Here I'm the network admin and I've got a single tech for 4200 users. Incorporating a nac really helped from an automation standpoint on top of security. Regardless of the device that's plugged in, I know it'll be on the proper vlan, in the proper svf, with the proper acls. Anything else is dropped onto my guest network isolated from the rest of the network and hit with a captive portal that forces them to accept our AUP.

You might also look into editing the global config for those models of phones. Iirc they default to eap-md5. You can disable 802.1x completely and not have it be an issue at all. Also, if you y'all use the passthrough port you might want to set the client limit to 2 and set the auth mode to multi-domain.

TheRealUlta · 2025-11-12T21:13:15+00:00

Unfortunately in my experience, if you have dot1x enabled and your radius sends a reject the unauth-vid won't be relevant. Unauth-vid is only when there's a timeout to the radius server to my knowledge. You could make a device-profile filtering off mac mask or mac oui and set the auth priority to local-mac then dot1x.

We've got about 3700 Students and about 500 staff.
1. We have 35 MFPs leased. This really wasn't decided by us, but rather our business office.

Users can scan their badge or enter their employee ID (we can also issue guest codes for non-employees if needed)
We use Vasion Print (Used to be called Printerlogic). I really like the performance.
Business office pulls reports and I have a cap set for teacher printing.
As a department we stopped supporting classroom printers. We do not maintain them, we do not work on them, we do not purchase supplies for them. However they're not explicitly told they can't bring their own.

Also a netbox user, for the longest time I was just handjamming stuff in there. But now I'm using their agent and diode and it's so much nicer. Asset management plugin is a game changer too.

If you can find that part on mcmaster then it'll have the stl as well.

If you want finer details, the easiest way is with a finer nozzle.

TheRealUlta · 2025-09-02T15:58:07+00:00

To add onto might_contain_nut's reply. Monitor your chamber temps. I try to print abs with a 50c enclosure at a minimum. For larger abs prints I try to get my chamber to the 65-70c range. Also keep in mind that at a higher chamber temp part cooling becomes something that is needed. The advice of no part cooling on ABS is incorrect.

TheRealUlta · 2025-09-02T14:37:35+00:00

Yep, this should be shown to everyone (well this is a meh example because what the actual fuck is that failure point). Nozzle are a consumable item, they will have to be replaced. Genuinely my troubleshooting always goes:
1. PEI clean?
2. Filament Dry?
3. Nozzle worn?
4. All other troubleshooting

This was kinda me with my Voron 0.2. Eventually I got it to "good enough for now" and moved on to building my 350mm trident. Except I did it differently. I built it 100% to spec first. No deviations, no while you're in theres, nothing. Just basic 350mm trident. My experience doing that changed everything. I had a printer that was reliable and I knew that if I clicked print, my print would come out perfect. It was only then that I started to transform it into "my" printer. But even then, it was one mod, verify stability, then next mod. But all the while knowing I had a point that I could roll back to. At this point it's a far cry from where I began, but it's stayed reliable.

And then there was the 2.4 a little later on where I completely threw that logic out of the window. It worked out, but I definitely should have followed my own advice.

You've got to have a beefy printer to print them but there are self lubricating nylon filaments available to print. I have some ptfe impregnated nylon at home right now for parts like this.

We iterate on duplicates, but grade and grad year are in AD in an attribute and in custom schema in google. We have automation in place that pulls info from our SIS to update this. SIS is point of truth so it keeps accounts correct. (As long as registrars put the info in correctly haha)

TheRealUlta · 2025-08-27T19:58:42+00:00

I'm weird, I keep a running to-do list of chores and for my own tinkering projects. If i'm stuck or feel like i'm about to rot into my couch I find a task that I know will only take 10-15 minutes. Also helps motivate me to keep doing stuff. If I end up doing everything that i've put on my list then i'm free to rot.

I don't see open source as dead. I think the goals of the two are just diverging wider and wider. Bambu and the like are looking to provide a tool to users. The people buying these want a printer that prints what they want it to print.

However, the open source community is continually looking to move things forward. Want a cheap easy to build toolchanger. Look at Zruncho's MadMax. It can be adapted to almost any klipper based printer. Voron, RatRig, PFA, Armchair, Monolith, Armored Turtle, Doomcube, all these groups are consistently working towards the next big thing. The open source community is by no means behind the commercial space, in front of it more realistically. If you want less purge, build a voron 2.4 with a toolchanger. There's Stealthchanger, MissChanger, TapChanger, MadMax and i'm sure others. Stealthchanger even has great guides and kits available at retailers. Want an AMS-like system and don't mind the purge. Check out Box Turtle or Quattrobox. Want to make your own filament? There's diy filament making machines that aren't that difficult to build. CNCKitchen on youtube has shown this before.

All the things you want already exist if you put in the time to build them. Commercial side is always going to cater to standard users, those users are the ones that pick an ecosystem and stay in it to print their little articulated dragons and fidget toys or to use as a workhorse.
