Dear people,
Iam trying to mill a large pocket in a piece of wood which need to be the same distance between the upper outside stock and the lower outisde stock. The gcode is correct in fusion360 but when I machined the part the lower dimension is 9,5cm and the upper is 10,5 mm. When I try a smaller part with the same feature it is correct. So looks like mach4 shifts the y coordinates when it starts the program. The x values are the same as my drawing but the Y value is shifted.
It is strange because when I try a smaller part, with the same feature and adjust the feature dimensions to the stock size, the problem does not occure
I use g54 to define my work coordinates. Could someone please help me. Iam really lost what it could be
