ID 90015

Change of selection mode not permitted using direct selection.

Description

If TRC (G138) is selected directly, it is not possible to change the selected side after the first motion block.

When indirect selection (G139) is used and then a following motion bock without any relevant motion information in the current main plane, a change is made implicitly to direct selection mode. Therefore, this error may also occur with G139.

Example:

V.G.WZ_AKT.R = 5

G139 G90 G01 X10 Y10 F1000

G42 G01 X10 Y10  ; implicit change from G139 → G138

G41 G01 X30 Y12  ; the error 90015 is also output here.

Possible changes to the NC program:

1. Use indirect selection (G139)
2. Add additional motion block before changing selection side
