    Yeah sorry about that. I grind everything from D2 to A2 to M390 to S90V and 10V. Mainly I want to be able to focus on getting a good finish on M390 with the capability to get decent finishes...

    Thanks! I was wondering what that small line was for!

    So what is that cup behind the lube pump for? And why is it so inconvenient to get to if it needs to remain checked and filled?

    Ok just checked and the spindle on light comes on, but the main power light does not. It looks like it's 120v from what I can read on it.
