Sewing error management device, sewing error management system, and non-transitory computer-readable storage medium storing sewing error management program

A sewing error management system comprising:

• a sewing machine configured to sew a sewing pattern in accordance with coordinates representing formation positions of each of sewing stitches of the sewing pattern formed by a plurality of the sewing stitches, the sewing machine including
• a first processor, and
• a first memory configured to store computer-readable instructions that, when executed by the first processor, instruct the first processor to perform processes comprising:
• acquiring the coordinates representing the formation position of the sewing stitch being sewn at a time point when an error occurs in sewing of the sewing pattern by:
• acquiring a sewing speed set for sewing the sewing pattern and a sewing complete stitch number representing a number of the sewing stitches sewn from a start of the sewing of the sewing pattern to when the error occurs;
• deciding an error range, based on the acquired sewing speed;
• and
• deciding an error range stitch number, based on the acquired sewing complete stitch number and on the error range, using the sewing complete stitch number as a reference;
• acquiring coordinates representing the formation positions of the sewing stitches corresponding to each of stitch numbers included in the decided error range stitch number;
• and
• generating an error image obtained by drawing an occurrence position of the error on the sewing pattern, based on an image showing a shape of the sewing pattern and on the acquired coordinates using a coordinate range corresponding to the error range stitch number as the occurrence position of the error on the sewing pattern;
• and
• an external device including a display portion displaying the image, the external device being configured to communicate with the sewing machine, and the external device including
• a second processor;
• and
• a second memory configured to store computer-readable instructions that, when executed by the second processor, instruct the second processor to perform processes comprising:
• acquiring the generated error image, by the communication with the sewing machine;
• and
• displaying the acquired error image on the display portion.

• acquiring the coordinates representing the formation position of the sewing stitch being sewn at a time point when each of a plurality of errors occurs in sewing of the sewing pattern;
• generating a total error image obtained by drawing an occurrence position of each of the plurality of errors on the sewing pattern, based on an image showing a shape of the sewing pattern and the acquired coordinates;
• and
• an external device including a display portion displaying the image, the external device being configured to communicate with the sewing machine, and the external device including
• a second processor;

• a second memory configured to store computer-readable instructions that, when executed by the second processor, instruct the second processor to perform processes comprising:
• acquiring the generated total error image, by the communication with the sewing machine;
• and
• displaying the acquired total error image on the display portion.

A non-transitory computer-readable storage medium storing a sewing error management program for displaying error information relating to an error occurring in sewing of a sewing pattern formed from a plurality of sewing stitches on a display portion, the sewing error management program including computer-readable instructions that, when executed by a first processor provided in a sewing error management device, instruct the processor to perform processes comprising:

• communicating with a sewing machine over a communication interface, the sewing machine being configured to sew the sewing pattern formed from the plurality of sewing stitches;
• acquiring, for a plurality of errors that occur in the sewing of the sewing pattern, a total error image from the sewing machine over the communication interface;
• the acquired total error image having been generated by a second processor in the sewing machine by:
• acquiring coordinates representing a formation position of a sewing stitch being sewn at a time point when each of the plurality of errors occurs in the sewing of the sewing pattern;
• generating an error image obtained by drawing an occurrence position of each of the plurality of errors on a sewing pattern, based on the acquired coordinates on an image showing a shape of the sewing pattern;
• and
• displaying the acquired total error image on the display portion.
