1st Build, Second machine

[m_c]

Jonathan, do you even know what Michael makes with his machine?

I'm pretty sure he doesn't need 2.2kw to machine what he does, and I'd even say the kress has far more power than what's needed. I'll agree a water cooled spindle will be better for noise reduction, but I wouldn't say it's a priority.


As for the smoothstepper, if you do get one, the ethernet SS is very near production, and is reported to be far more stable than the USB version.

Yes I do know - spent some time discussing quite a lot about this and the machine over Skype, but not going to say here as that's up to Michael. I gather what he is making requires high accuracy. It's also generally small tools, so I guess the cutting noise wont be much which makes getting a quieter spindle sensible.

Yes if you actually got 2.2kW from the spindle - see what I put in post #102. Similarly if the Kress had far more power than needed Michael wouldn't have considered getting a Super-PID.
More importantly he needs the bigger collets that the 2.2kW spindle offers, so the only spindle to get is the 2.2kW water cooled (as air is too noisy and bad at low speed).
