Each ball screw has 3 bearings 30TAC62 , the screw is secured with an additional body (grinding cylinder with dimensions of 40-60mm ).

 

New servo motors for spindle and axis 

The drive is with Etercat and mesa cards for spindle and I/o port. 
 

 

 



I decided to make a foundation as shown in the machine documentation.Because my foundation was too bad…
20 cm of gravel and 60 cm of concrete.  


 

 

 



 

Looks great! I am looking to do the same soon.
May I ask where you are sourcing all your replacement parts from?

Thanks.

Which part are you referring to?
Do you have the same machine?

The machine has been moved. All 6 screws fit well.
