What is different between the minimill 6K and 10k spindle on the super mini?
Which one or all of the following would have to be replaced to upgrade a regular minimill to a 10K? Same question for a 15K

1. Spindle Cartridge?
2. Spindle Drive?
3. Spindle Motor?
4. Pulley ?
5. Belt?
6. Parameter Change?

Thanks,
