    Unexpected vertical tool offset following the change of workspace G54 G55 G56

    Hi,

    I wish to do a job requiring 2 tools in 3 Work Coordinates System (WCS) : G54, G55 and G56.
    Tool 1 must work in each WCS before changing to Tool 2.

    I use the option "Multiple WCS Offsets / Order by Tool" of the Setup in Fusion 360.

    I observe that the tool change induces a vertical offset of tool 2.
    This offset is precisely the difference between length compensations of tool 1 and tool 2.
    This difference is even doubled after the milling of the G55 to G56.

    e.g.
    Tool 1 Length Compensation -130,00
    Tool 2 Length Compensation -133.50
    Compensation difference = 3,50

    DRO Work_offsets at the end of the program:
    G54 X0.00 Y 0.00 Z0.00
    G55 X0.00 Y15.00 Z3.50
    G56 X0.00 Y30.00 Z7.00
    (The 3 Work_offsets are Y-aligned and spaced 15.00).

    I'm using Fusion 360 with Mach3, PostProcess Mach3mill_43262

    I tried to solve the problem by making changes in the program and looking for good advice on forums, but still unresolved.

    I would be grateful for if you could support me for this problem.

    Guillaume
