1. A cutting device comprising:
a platen;
a blade mount;
a cutting blade mounted on the blade mount;
first movement mechanisms, one of the first movement mechanisms having a first motor configured to move a holder placed on the platen and the blade mount relative to each other in a first direction, another of the first movement mechanisms having a second motor configured to move the holder placed on the platen and the blade mount relative to each other in a second direction intersecting the first direction;
a second movement mechanism having a third motor, the third motor being configured to move the blade mount in a third direction causing the blade mount to approach the platen and a fourth direction causing the blade mount to separate from the platen, the third and fourth directions being directions intersecting the first and second directions, the fourth direction being an opposite direction of the third direction;
a detector configured to output a position of the blade mount in the third direction;
a processor configured to control the first movement mechanisms and the second movement mechanism; and
a memory storing computer-readable instructions that, when executed by the processor, instruct the processor to perform processes comprising:
acquiring cutting data;
controlling the first movement mechanisms in accordance with the cutting data to move the blade mount and the holder relative to each other to a cutting start position at which the blade mount faces a cutting object held by the holder;
acquiring a contact position of the blade mount in the third direction output by the detector when the cutting blade comes into contact with the holder;
setting a cutting position in the third direction based on the contact position, the cutting position being a position at which an edge of the cutting blade in the third direction is located further in the third direction than the cutting object;
with the blade mount and the holder located relative to each other at the cutting start position, controlling the second movement mechanism to move the blade mount in the third direction to the cutting position;
performing cutting processing to cut the cutting object using the cutting blade by controlling the first movement mechanisms in accordance with the cutting data;
determining, during a period in which the cutting object is being cut on the basis of the cutting data, whether the position output by the detector is a separated position at which the edge of the cutting blade is separate from the holder, the separated position being further in the fourth direction than the contact position; and
when the position output by the detector is the separated position, re-cutting the cutting object using the cutting blade, on the basis of the cutting data.
