[Maya] MASH Curve node in Python

[Tomatoprincess]

Okay after 2 days somebody else found the solution. Maybe somebody have the same problem in the future :)
Just add the command

cmds.connectAttr('curve1' + '.worldSpace[0]', 'MASH1_Curve' + ".inCurves[0]", force=1)

curve1 is the Name of the curve in the scene and MASH1_Curve the name of the curveNode

Cheers
