This article is a stub. It needs to be expanded.

Getting crystolecules into huge scale free space
(larger than their won scale by several orders of magnitude)
should afford some easily manageable conscious effort.
If charged they can be free-space manipulated with conventional techniques.
Electric fields, magnetic fields, and optical traps.

Challenge of getting cool i.e. slow free space crystolecules

Cooling them down aka slowing then down is possible so far that gravity acting on them can be observed.
(wiki-TODO: Check that claim, there can be significant heat-up problems from the laser intensity.)
But these crystolecules are far outside machine phase deep inside gas phase (or dystactic phase).

Instead, keeping crystolecules …
– close to the emitting source and
– inside a small volume not much bigger than their own size, and
– having them without a charge is likely quite difficult.
Requites getting crystolecules ejected at at typical nanomachine speeds of a few mm/s
(constant speed control, in mechanical analogy to constant current control).
Or requires to at least get them quickly cooled down again after high speed ejection.

Due to intercrystolecular forces being many orders of magnitude bigger than gravity (at these small scales)
either they stick like very strongly or they fly off very fast with a lot of kinetic energy.
There is no easy pushing them off a surface (or out of a tube) gently and
they fall off and down by gravity locally at scale similar to their own size right after being fully pushed-out.

Crossing the heat-overpowers-gravity size-scale crystolecules rather "fall" in a
relative to their own size very large parabolic arc. That is so far they are in a good vacuum.
In a gas they are diffused away to who knows where.

Growing positional uncertainty from quantum dispersion and (if in gas) Brownian random walk

For small crystolecules and typical machine speeds of mm/s quantum dispersion speed of position is relevant.
(wiki-TODO: Ad a very crude caculation to show the scales.)

Probably the case: In a gas the quantum dispersion more or less mixes with a statistical Brownian random walk.
Free floating crystolecule decoherence due to a collision with a gas molecule is not fully decohereing the free floating crystolecule relaive to the nanomachine bulk if the gas molecule itself has some degree of quantum dispersion relative to the nanomachine bulk. Relational quantum mechanics.

High energy ejection out of machine phase into dystactic phase

Simulation by Philip Turner. Beware of misleading aspects in animations of diamondoid molecular machine elements. Pauli repulsion pushes the piston out of the slightly too tight cylinder. The effect gets weaker with progressive push-out but still suffices for a final ejection. A bend snap makes for a sudden re-acceleration and for strong excitation of mechanical modes. As a side-note: There is also some significant conversion to kinetic energy. This is around tens to ~100m/s. More like a crystolecule cannon than a gentle push-out.
