I'm not sure if I am doing something wrong or if my lathe is acting up.
I'm roughing out a large bowl, and I'll have the lathe going at 200-400 RPM. Without hitting any buttons, I turn the speed control knob down to 0 to check my work. Again, without hitting any buttons, I then adjust the knob to increase the RPMs. Nothing. It won't move. I've tried removing tension from the belt (so the motor can spin freely), giving the blank a push in the right direction before increasing the speed, turning the direction switch to neutral then back to Forward, etc. Nada.
The only thing that works is hitting the red power button on the lathe, waiting until it fully shuts down, then starting it up again. It'll run great without issues or doing anything odd.
I've only noticed the issue on the two big bowls (20 inches+ diameter) I've done and never on any of the smaller ones. it doesn't happen all the time, but enough it's annoying as all get out.
The only thing I can figure is that on these large blanks, they really continue to spin after I turn the knob to zero. I'm not sure if this is causing the motor controller to freak out or anything-- but I can't really explain why I haven't seen the issue on smaller pieces.
Thoughts?
