Bed adhesion is usually the biggest issue, often attributable to the z height being off, and a lot of older printers didn’t have z-axis sensors or the software to accommodate for the variances, so it involved the old paper test. Depending on the printer, it might shake itself out of its z height setting while printing. A lot of people ended up spending as much as the cost of their printer upgrading with after market parts to try to resolve some of these issues.
I haven’t used the Monoprice before, but my research says that Monoprice doesn’t make their own printers. They just rebrand someone else’s. So the Monoprice Maker Select appears to be a rebranded Wanhao Duplicator i3, which looks like it came out sometime in 2016. So while you might have bought it six years ago, the actual printer design is much older and missing out on possibly 9 years worth of innovations.
If you can eventually afford to replace it with something else, there are some sub-$400 printers out now that might give you a much nicer experience. I started with an Ender 3 v2, which was a pain, similar to what you experienced. I upgraded to a Sovol SV06, which was great (and recommended to me by a professional with a print farm and wide variety of printers). Now I’m on a Prusa CORE One, but I don’t recommend spending big until you know you’re really into 3D printing. If you do consider buying a newer printer at some point, I’d recommend seeing if you can see someone else’s in action so you can experience the difference. Makerspaces might be a good resource for this.
A pattern I’ve noticed isn’t the legal aspect, but rather the monetization. Everyone is offering a platform where an obscure writer can pay to give away their writing for free or pay for an ad campaign where you’re spending more on ads than you will otherwise make off your work. One of the significant advantages for writing is that it requires very little overhead versus another activity like making physical objects that require equipment and material. But the market is saturated and publishing platforms are harder to access unless you’re a guaranteed seller who is already somewhat famous or has a built-in following. And there’s always someone out there willing to “help” by taking your money for the promise of connections and exposure.
It reminds me of the old poetry contest scams where you submit a poem, they tell every poet that they’ve “won” and will be published, and then they offer a “discount” for poets published in the book to get print copies for you and your friends and family, but the book is only advertised to the poets.
It does seem like there should be more open and free resources for this—websites where authors and readers connect without barriers or monetization. There probably are, but they don’t show up high in search results. Obviously they’re not going to be seen before all the paid options with ad funding.
