### Description

We present a recent lattice QCD investigation of charm tetraquarks. After describing some of our new methodology, we demonstrate its use in calculations with unphysically heavy light quarks such that the pion mass is 391 MeV. Spectra in the doubly charmed and hidden charmed sector will be shown including those which are of relevance to the experimentally observed charged $Z_c$ states.
