The name Maschik was not found in the surname databases I checked. Names that sound similar to Maschik are: Macek - Czech, Majewski - Polish, Masek - Czech, Miazga - Polish, Myska - Czech. It is likely Maschik came from one of these.
I'd go with a Slavic language board. The -chik is usually a diminutive in Slavic (mostly Czech or Serbian) meaning "son of" or "descended from" etc.
