this is a bit mysterious, I suggest that get_last_entry (in a factored-out version) throws the Empty exception and then you can have the much more compact:
try:
mov_amount, mov_type = self.get_last_entry(self.input_queues[axis])
if mov_type == MovementType.relative:
...
except empty:
return| value = motor.home_pos | ||
| self.input_queue = input_queue | ||
| self.output_queue = output_queue | ||
| self.mov_type = MovementType(False) |

you would rather use the enum as MovementType.relative (the point of using Enums is that this mapping true, false or integers is arbitrary)

this can be factored out in thecolonel (which can also get a new culinary name)

this appears in many places, I suggest to factor it out

| if package: | ||
| mov_value = package[0] | ||
| mov_type = package[1].name |

again, this goes against the spirit of using Enums

the point of using Enums is to avoid string comparisons

axes can be an Enum and this function just a dictionary lookup

this again is the queue quering pattern that should be in a separate, common function
