I'm not a chemistry major by any means, but I theorize the process of separating Gramine from DMT is difficult to impossible for an amateur. The only real option for the amatuer without access to a full-scale lab is recrystallization of the DMT out of the Gramine. The problem is that DMT and Gramine are so close chemically, that I doubt a "magic solvent" exists that would allow the recrystallization. It would have to satisfy these parameters:
1. DMT - insoluble at room temperature.
2. DMT - soluble at boiling point of solvent.
3. Gramine - soluble at both room temperature and BP.
This would allow the recrystallization of DMT while the Gramine remains in the solvent. If you can find this solvent, or an opposite solvent (to recrystallize the Gramine rather than the DMT), than you can separate them. In the later case, you would discard the Gramine crystals and evaporate the solvent from the DMT. As for the solvent, you may be able to try Heptane, as it's an excellent DMT recrystallization solvent, but it's solubility of Gramine remains in question. As for determining that, you're on your own.
Basically, I can only recommend you don't worry about the Gramine in your DMT. It's still very possible to get those "breakthrough doses" with Gramine in your crystals.
For more information about recrystallization, there's a how-to video on MIT's website here:

hmmm....
well, there's column chromatography --- just check out the Rf(s) for the various indolic compounds & pick a workable solvent pair...
& maybe playing with a/b phase extractions (& variable solubilities of several salts & solvents at different pH values...)
& then there's vacuum distillation (sublimation of DMT under reduced pressures...)(this might be "the easiest" method, 'cause i'm sure that dmt & gramine would sublime at different temps under 0.1 Torr, or 0.01 Torr...)
k heb geen tijd gehad om t te vertalen naar nl, maar t schijn vrij moeilijk te zijn om gramine en dmt te scijden zonder een voledig lab.... maar we zoeken door
