ok so iv had my id liner about a week now and i cannot for the life of me pull a clean line with this machine, iv found myself picking my standard brass up halfway through the tattoo, not saying there is a problem with the machine as it seems to sound and run fine but im wondering if there is anyone on here with this machine and how they use it, volts, hard/soft grommet ect? i have the 3.5 stroke btw, thanks in advance
