Wow, I never knew the vacuum can cause so much trouble! I have over 80hrs on my machine and for the past 3 months have vacuumed it 4-6 times per carve depending on how long the carve was. My theory was the cleaner I keep my machine during the carve the longer it would last and the less trouble I would run into later. I just use a regular shop vac and have not had any trouble. I guess will have to be more careful and cut back on the vacuuming. Thanks for the heads up!
