So, I suppose this is the best place to post this. I got a treasure chest from Throwhammers with an estimated less than 8 hours of use and have since put a minimum of 8 hours on it. Now yesterday a strange thing happened. I had been running it long stroke and had switched to medium stroke. Everything was going well running as it had been since I had it. I had done some black shading and was switching to color. All of the sudden the machine sped up. Maybe 20% faster, to exactly where I had always wished it was. I had been running my voltage high near 11volts. Now I was able to come down to high 9s. So after this long explanation my very basic question is " does this machine have a break in period?" it ran great before but now it is a monster. Still quiet no different noise just faster. I ran some outlines today and I was lining as fast or faster than with coils.
