How to check where is the fault of Ambition Tattoo Machine? Batteries, motors, or stroke cams? 

Thank you for this. I’ve noticed my pen is not pulling clean lines lately so I have been wondering how to go about iy

Dud thank you this saved me

I heard really only good things about the torp model

What if my stroke cam isn't working easily? And machine heats up fast, the needle isn't even working up it down.
