Yea your experience is very relatable over the las 4 years of so ive been in 3D printing 3 of those years are using the ender 3 v2 and i too also experience electricak shocks due to bad earthing. But this new printer really is quite the game changer not only for those who is in the 3D printing industry but also for newcomers who doesnt have to learn the steep learning curve from the old ages of 3D printing
