The MB-4 Version 1.30 program update contains new features and improvements:
New Feature:

Resolves jump thread trimming
Number of jumps feature now correctly recognizes the number of programmed thread jump commands in order to differentiate between a jump and a trim in a manner common to commercial embroidery.

Position adjustment while embroidering
Embroidery position can be adjusted with the jog keys even after starting to sew a design. This is a powerful feature for when embroidering multiple instances of the same design and needing perfectly precise alignment in the hoop, for instance when embroidering decorative buttonholes.
