Masa Harina and a pasta roller?
I have mede pasta years ago with regular corn flour (not cornstarch, but just a non-nixtamalized version of maseca or very finely ground cornmeal if you wish) and I don't remember much in terms of the recipe, but I remember that it worked well in the roller and that the result was awesome. And I don't see a reason why you couldn't do the same with masa harina to add a little bit of the delicious nixtamal flavor (like they did here) =)

I tried to google a corn pasta recipe to link to (as I couldn't remember mine) ... and one of the first hits was - guess what - with masa harina. Here is the video, where it seems like they also use a pasta roller with no problems, but they were trying to make something gluten free, but there are a lot of other cornmeal pasta recipes online that use regular flour mixed in.

Just some thoughts on masa flour: in my experience when you making a firmer dough it often tends to come out a bit more crumbly ... but I had good success (if I wanted a bitt more compact workable dough) by mixing it 1:1 to all-purpose flour. The nixtamal flavor is strong enough that you still taste it well even if you use more wheat flour. Sometimes I also add a couple of drops of oil so that it isn't so sticky (you can also use other fats ... like the masa for tamales often calls for lard).
