I'm starting the conversion my Sieg X3 to CNC using the CNCFusion kit and about to order the remaining stuff from Zapp.

I'm looking to use the CSMIO/IP-M and EM806 with two Nema 23 and one Nema 34, or possibly the Easy Servo Closed Loop system (ES-D808 and Easy Servo motors).

This is my first CNC and will be for hobby use mostly. I have a few questions:

- Firstly,is a closed loop system worth the ~60% increase in cost? I don't want to waste money which could be directed elsewhere obviously.
- The ability to cut threads would be useful on the converted machine (occasional use). What's options are there to accomplish this?
