Hi Mr Xushuo:
Yes, that is an X1 CNC. The main problem with it is that it has servo motors that are under powered. It will not loose steps because of the encoder but it can easily go over current and then it will stop. My only solution is to have it move very slowly and adjust the acceleration to be very gradual so it does not stall.
I did research on building my own X3 with servo and stepper motors. If the stepper motor is sized correctly it will be nearly impossible to loose a step unless you run into a hard stop. Using servo motors presents many other problems and would not be a good solution for an X3 machine. You are using the same size stepper motors and ball screw lead that I calculated would be best for this machine.
I am looking forward to the new CNC Mill. I am going to try to use the existing enclosure if possible and make some changes to support the longer table and increased travel.
I think an enclosure would be an excellent option to offer for your unit.
