  • Other recommendations are great but you could also try some type of adhesive AFTER you’ve eliminated any other potential problem sources.

    It does look a over extruded. Have you calibrated your esteps? I always need to do that when changing filament types and sometimes even between rolls of the same filament type (especially bargain bin PLA from amzn)

    My ender 3 with a textured glass bed sticks perfect with PLA and nothing else. For some reason PLA+ tends to lift. Glue stick helped with PLA+ but I hated dealing with because it REALLY stuck so I switched to masking tape. That does the job and is easier to remove. On my CR-10 with plain glass bed (no texture) I use hairspray… Mostly because that’s what the guy I bought it from recommended and, to be honest, it does work amazingly. Nothing sticks to that glass plate bed without an adhesive but it pops right off once the bed cools down.

    That said, I don’t recommend “extra” adhesives unless you’re fully sure you’ve solved any other potential problems. They can be a help/bandaid but if the root cause is something else then you’re just masking it.

    Some materials and beds need some help, some don’t. I primarily use PLA and PLA+ with the occasional PETG and TPU.

    I’ve been on mint for ages but when I updated my RAID this year it originally wouldn’t recognize it. I eventually got it recognized but it capped the 16TB drives at 999GB for some reason. For fun, I went up the chain to Ubuntu… Same thing

    In frustration I went to Grandma’s house with Debian and it worked perfect out of the box. I’d spent hours researching it but the best I found was a potential RAID related bug (lvm, specifically, I think) introduced in Ubuntu that, of course, filtered into Mint. Even fdisk reported the physical drives as 999GB in Mint/Ubuntu.

    I still don’t know the exact cause but I got it up and running so I’m a Debian guy now, I guess.

    Granted, my use case isn’t super normal since I’m using a BIOS RAID1 (and we all know how fun BIOS RAID can be) with full disk encryption.

    Worked out in the end but it made me sad to ditch Mint









  • The relationship with the instructor is something I wanted to touch on but thought I’d maybe rambled too much already.

    If it’s a good program, they WANT you to succeed and they want to give you every possible advantage. You can show up to class, do the bare minimum, and maybe pass. But going the extra bit and asking good, useful, questions will get you much further.

    I’ve never met an instructor who cares that isn’t up for side discussions, private tutoring, and literally anything that helps the student squeeze as much info as possible before, during, and after the class. I have zero respect for anyone who teaches a class and refuses to do anything outside of the prescribed class hours… Makes me angry just thinking about it.

    Edit: also if the instructor is working in the industry then they have a network that you can tap into… which is often more important


  • Be careful about “boot camps”, and I say this as someone who teaches at one on the side (coding, not security). A lot of them are kind of like degree mills - pay money, get stamp, maybe worthwhile or maybe worthless.

    If you go that route, do a lot of research. The biggest thing I’d look for is that the instructors work in the field full time and teach on the side (because they love sharing info and teaching the next generation). Hire rates for grads is also a good indicator… But take close note of where those hires are at and ask if it’s not published.

    Any time I’ve come across these kind of programs where the boot camp instructors only job is teaching, the info is usually 10+ years dated and relatively useless past the absolute basics.
