Like others mentioned, it doesn’t seem far off stock. The things I can pick out that are mods are:

• bl touch (or something like it). This is an automatic bed leveling tool. So instead of spinning the little cogs under the bed all the time to get the bed level, it will probe the bed before printing to build a map of the bed position, and print accordingly.
• general parts upgrade. This is a simple upgrade kit that’s just an increase in quality. Better springs, stuff like that
• mainboard upgrade. Might just be upgraded to a silent board. Might be upgraded to something more… hard to tell.

I don’t see much else that stands out as being particularly modded. Hope that helps.

The person you are replying to is talking about pink sky being built on bluesky, and you equate that to Lemmy being based on Reddit. One is a hard technical dependency, and the other is a conceptual inspiration.

You are engaging in an equivocation fallacy, and I think you know that. You even try to sneak it in by switching to a different but similar word (built->based) with a different meaning, then you switched back again to “built” while using the term in the same way you used “based”, then you start using other phrasing to obscure it even more. You are gaslighting with word games to try and get people to not notice your fallacy. It’s super dishonest.

JavaScript has nothing to do with Java. They are completely different languages and environments.
