With that one (creality textured glass carborundum something or other) I kept hitting it with 95%+ IPA, it just gives out eventually. I switched to a textured spring steel plate recently, world of difference for petg, PLA, and tpu. It’s just another consumable :/
If you’re not ready to switch yet a layer of masking tape can get you by for awhile, it’s just a pain because the masking tape will need to be replaced about every other print depending on your settings.

It looks like a glass carborundum Creality plate. I have one of them, they work really well until one day they just don’t.

What did you do to that poor build plate?!?

It’s bad at anything useful for programming too.

Welcome to late stage capitalism where the game’s made up and the points don’t matter.
Privatize the profits and socialize the losses.
I’ve tried to use “AI” to help me with minor programming tasks, or to start basic projects, it’s really bad. As in, it takes me more effort to fix the garbage it outputs than it would have to write it from scratch. In addition to that, it writes things badly in non-obvious ways. Junior engineers make similar mistakes to each other, because they’re working logically. “AI” makes weird mistakes because it’s not working in the same way a human mind does.

It’s 0.2 layer height, I wanna say it was 3 layers, but it could have been 4. The green I’m using is opaque at even one layer with these settings though

They’re manual changes. Annoying, but they work for basic stuff.

I’m excited to introduce you to this if you haven’t seen it!
teachingtechyt.github.io/calibration.html
I use this as a general guide for every time I buy a new material, manufacturer, and/or color of filament. There’s YouTube videos explaining everything every step of the way.
For a new printer (or significant modifications) I’d go through the whole thing. For new filament, if I haven’t used it before, I do flow calibration, temperature tuning, retraction tuning, pressure/linear advance tuning, and max flow tuning, not necessarily in that order. I’ve found that as I’ve learned and experimented more I’ve branched out into more esoteric tools for some things.
My filament printer is a fairly heavily modified ender 3 pro (spider hotend, direct drive, dual z axis, spring steel bed, solid bed spacers, herome gen 7 cooler, cr touch, stepper driver diodes, and an adxl345 waiting for me to mount and wire it… I think that’s it). So I’m not saying this as a Creality hater, I love my ender, I hate their software and firmware. I had a terrible time with their Marlin firmware and ended up building it myself. I’ve since switched to klipper though and highly recommend it, it got me a reasonable quality benchy in around 30 minutes.
My point there is that I have had a hard time with the default profiles across the board, even before the mods. For filament printing I use Prusaslicer, though I do like Superslicer and Orcaslicer seems nice as well, I just have all my profiles built for Prusaslicer and it generally just works.

I’m only adding this because I don’t already see someone mentioning it.
My first thought was bed leveling, because that’s always the first thing, especially with weird surface artifacts.
But looking at the bridging “above” the text and the gaps in the interface between the solid infill and your perimeters I suspect that you’ve got some under-extrusion going on.
Have you tuned your filament? If not I recommend giving that a shot and seeing if it doesn’t clear up those issues.
- Comment on What is on your "things to 3d print" list? 1 month ago:
I just “finished” a herome parts cooler upgrade on the E3 pro. And holy shit has it made a difference.
I’m in the process of printing random gardening stuff while I put off setting my Saturn back up. I am like a year behind on printing Loot Studios stuff. I wanna paint some minis so bad.

Zwave is great too, but still no video. Wired is the answer.

Expand the Supreme Court and add Kanye, King Charles, and Elmo. At least that shit will be entertaining.

Mm wave sensors are way more accurate than pir sensors, they also don’t stop “seeing” you if you’re still in the room, just still.
Mm wave sensors can detect breathing as movement.

Interconnected hardware and software systems do affect each other. It’s not magic, it’s physics.
And yes, your graphics card spewing garbage onto the pci bus can affect the rest of your system.
It actually does work like that.
- Comment on Rivian blames “fat finger” for infotainment-bricking software update 5 months ago:
Dollars to donuts their infotainment system shares a CAN bus with nodes that affect control systems. If they can’t handle the easy stuff, what the hell else are they fucking up?
It’s not about the infotainment system, it’s about the culture that leads to this problem.
This company will not end because of this issue. Boeing is still kicking and you can actually count the number of people they’ve killed with shitty software/system integration process.
I’ve spent my career working in embedded systems and embedded test and verification. This issue is not the first or only issue to get by. Maybe they take this like the red hot poker it is and fix their problems, maybe not. I’m not gonna gamble on their products though.
- Comment on Rivian blames “fat finger” for infotainment-bricking software update 5 months ago:
Anyone who builds software that runs on actual hardware should know that you NEVER deploy builds that haven’t been fully exercised on actual hardware.
This tells me that their software QC process is non-existent at best and actually malignant at worst.
If their software is supposed to be their defining feature this is the equivalent of McDonald’s “accidentally” shipping frozen discs of literal shit instead of burger patties to franchises who then serve them to customers without question.
If their company dies because of this (it fucking should imo) they 100% deserve it for the countless unknown dangers they’ve exposed their customers to. It’s not this particular thing, bricking the infotainment system, it’s the demonstration that they have no or bad process.

- Comment on [deleted] 5 months ago:
The short answer is “practice”
The longer answer is, do it a lot. Listen in code reviews. When you investigate bugs, do actual root cause analysis, understand the problem, and understand how it got missed. Don’t stop learning, study your languages, study design patterns, be intentional in what you learn.
I had good mentors that were hard on me in reviews. Developing a thick skin and separating criticism of you from criticism of your code will help a lot in terms of learning in reviews.
