A couple of days ago I was happily working on something when something odd happened. The lathe was running around 400 rpm (I don't get exact readings with this model), I was very gently moving the Y axis in further and it was cutting cleanly. I just as I was moving it out, the motor seems to increase to what I can only guess was around 2000 rpm (which is what it's limit should be). My hand was nowhere near the dial. I then slowed it right down and moved everything out the way. When i turned it back on it sounded like it was going up to some rediculous rate when turned further up... then it went back to normal, and I carried on with the job.
Electrical problems? I'm a little concerned. I've only had it 4-5 months and it's still under a 12 months warranty.
