I'm not sure what the proper "Marxist position" is, but the vulgar Marxist idea that "the problem isn't with technology itself" is rubbish.
Technology is a way to codify power relations in production. Technology is never neutral. Sabotage is of course one way to challenge this power, but changing the technology, and the power relations it represent, is how you "seize the means of productions". Just adopting the "master tools" won't be enough.
Marx' portrayal of the Luddites was built on the myths created by the English bourgeoisie which crushed them, so I wouldn't lend much weight to that part of his writing.
