Those are gone, and also the Potato stuff is gone.
The Voiding shard is also gone, but I assume the latter two were removed purposefully, the machines worked, at least the casting one.

Yes, everything was removed intentionally. The machines because while they may have worked were still very incomplete (untested, had no recipes, had no basic-resonant variants, etc.). Everything else was removed because those features are all provided by other mods. Now if everything was complete, I would've ported them, but since there seems to be a lot of a public upset around those unusable features, it just seems logical to give people what they're told they are getting; including no more and no less.

Untested, probably.
The Ingot and block casting machine worked, it had recipes for basic to resonant, if thats what you mean by recipes. I straight up never used the Part caster, so I wont really comment on it.
At least look into the former machine,
