My prints up to this point have been okay, but not great. Serious stringing seems to be an issue here, and one of the things I've notice is that the further along the print goes, the more it seems like the print head is almost grinding into the print. To the point where if I'm printing something like a minifigure, it will get ripped apart mid print. Am I overextruding? Missing z steps?
Filament is Overture PETG, Nozzle is 230C and bed is 80C. I have it in an enclosure. I'm running it from a laptop set up with Cura.
Depends on the webapp, traffic, etc. I have an EC2 instance and my own domain that runs me a solid $7 a month. It's just a tiny little web server. If your web app is structured in a way that the client does the processing, your hosting costs can be pretty cheap.
For instance, rather than editing a PDF on a server, if your web app provides all of the tools to edit the PDF in the client's browser, the server doesn't need to be particularly robust. Basically it just needs to hand out those tools to the client.
