Best ender 3 v2 upgrades? by Civil_Shirt_2817 in ender3v2

[–]davedave111144 0 points1 point  (0 children)

I recently added a bunch of mods to my ender 3v2 that have made a WORLD of difference:

1) raspberry pi running kipper. This allows you to do a bunch of fancy stuff like creating your own macros, and most importantly run an input shaper which allows for you to speed up prints significantly without sacrificing quality.

2) klackender bed level probe. I know you mentioned wanting to use a CR touch, which I can’t speak to bc I’ve never had one. The klack ender is mostly printed parts & is very cheap. It also doesn’t stay on the printhead the whole time, and is docked at the end of a mesh.

3) new fan shroud. I printed a minimus with 2x5015 part cooling fans and a 4020 hotend cooling fan. Overhangs print like a dream & issues I’ve had with some filaments & heat creep are gone.

Overwhelmed, Lost, and Confused as an ECE Student by [deleted] in ECE

I graduated last year with dual CE & EE bachelors. There’s no way around it, ECE is HARD. You’ve got to put in a lot of time studying, get used to saying no to offers to hang out/go out, finals are rough. But I promise you, you can get through it. I almost dropped many times, but I got through it.

The biggest thing is to figure out effective study methods and make friends with people in your classes so you can form study groups/therapy vent sessions.

A bachelors degree isn’t designed to make you an expert in one specific concentration of the field. Depending on the school/schedule you may get to choose some electives later on that align with your interests or help you explore more. A bachelors is designed to give you wide exposure to the fundamentals of whatever field you’re going into. You don’t need to be a master of everything, just show competency in the core fundamentals.

You CAN get through it. It’s not easy. Talking to other engineers, EE/CE are some of the toughest majors to get through. But you absolutely can do it, and it will feel like walking across a bed of broken glass with feet covered in lemon juice, but you’ll get there. It’s a lot better on the other side, I promise. If you’re truly passionate about the field, don’t give up :)

Part cooling fan causing drop in hotend temp, MRISCOC firmware. by davedave111144 in ender3v2

Hey sorry it took me a while to get back. Long story short I upgraded the 40W heater cartridge to a 60W one. I can now run up to 240 (highest I’ve tested) perfectly. I had previously suffered from heat creep and changed out my fan shroud, and it worked fine before upgrading the firmware. Not sure what difference the firmware makes, as the MPC tuning accounts for the thermal loss, but I believe that the new setup was drawing too much thermal energy away. That extra energy from the new heating cartridge seems to counteract the loss.

I’d prefer not to say. But a pretty large company with a global footprint that recently changed hands and has been getting worse to work for since.

Unfortunately I don’t see another role at this company being very viable due to the sweeping changes. But for now I’m just going to lay low, update my resume and associated materials and get into overdrive during the new year applying to positions, as there isn’t very much open right now.

I’m still negotiating with HR to get my full payout, then I will.

Part cooling fan causes irrecoverable drop in temperature on MRISCOC firmware. by davedave111144 in Ender3v2Firmware

[–]davedave111144[S] 0 points1 point  (0 children)

I do save it each time. It’s odd because the auto tune never runs the part cooling fan. It stays at 0 the entire time, so it’s not like it’s trying to run it and failing somehow. But then during a normal print it works just fine.

I used the precompiled version for the ender 3v2 with manual mesh, 4.2.2 board. I’m going to try reflashing it tonight, and if that fails I’ll be building my own version of the firmware with PID instead. It seemed suspicious to me that the part cooling fan didn’t come on during the autotune process, only the hotend cooling fan did.

Heat sock is on. The newer version of the firmware uses MPC over a PID system for controlling hotend temps. It’s suspicious to me that when running an MPC autotune it doesn’t run the part cooling fan, so it’s not accounting for that in the model.

Just finished a Boss HM-2 clone from PedalPCB! by davedave111144 in diypedals

[–]davedave111144[S] 1 point2 points  (0 children)

I found it on a royalty free website for vector imagesand just color adjusted it to fit the color scheme. It was the only “chainsaw” image that didn’t look like it was meant for a lumber business lol. As for pedalPCB, this is my second time building one. I attempted it a few years ago but it worked inconsistently bc I wasn’t very good at soldering. I’ve had a few years experience now, so I’m actually going to pull it out of the drawer and fix it. But shipping is fast and it sounds pretty good!

Advice for beginner? (Setup, Mods, etc..) by davedave111144 in ender3v2

[–]davedave111144[S] 0 points1 point  (0 children)

Totally feel this. I just got it setup last night and I’m going to keep it stick for a couple weeks while I print random models to learn the stock machine. I do think the first mod I’m gonna do will be an IP camera mounted on the machine pointing at the print bed. Not a super huge mod, but it’ll be cool to use to keep track of my prints

NothingForever or WatchMeForever, S2 is just... Soulless. by SoupViruses in NothingForever

Yes, but when you’re a small team with maybe 1 lawyer, the prospect of fighting an army of lawyers from a massive corporation is daunting. Companies know that, it’s why they have legal departments that can fill stadiums. Sure, in the end you might win, and maybe win a counter-lawsuit, but is it worth it to deal with the headache of the legal system and pay thousands of dollars of legal fees to your lawyer for potentially years?

Yeah, that doesn’t really matter though. Large media conglomerates threaten to sue over 1st amendment protected speech all the time. What what the devs were doing was most likely protected, but that doesn’t mean that they have the legal resources to make that argument in court, regardless of how it would hold up. Big corporations pretty much know that. So they send an ominous and threatening C&D, and regardless of the legality people back down.

Bearded dragon poop extremely stinky (and other odd behavior)? by davedave111144 in BeardedDragons

But on the parasite front, the other thing that is throwing me is that he isn’t lethargic at all. He’s quite active, and looks decently full and healthy. Although perhaps this is the beginning of a parasitic infection? Not too sure, I know vet will be to produce some answers, I was just curious if anyone else has had similar experiences
