I have tried an ALTERNATE Platting method as suggested by another knitter and find it to be very satisfactory.
It is for stockinette only, but is more convenient for color changes.
The appearance is identical.
Color A, feeder 1
Color B, feeder 2
Stitch dial, L or punch/thread lace
Side levers, set to the “circle”, non patterning.
Bottom 2 sections of the test sample. They look appear to be the same as the top 2, which were using the PLATTING feeder.
