As of 2020 July 1st, there are four changes being implemented gradually:

 


1. The Z axis up/down buttons on panels have been applied since Container#20.

 

 

2. Some machines now are with chiller connected to machine.(gradually from Container#22)

 


3. The waste collecting drawer/ drop tray. (gradually from #23), this feature will start from Nova 35\51\63, drop tray for Nova 24 will not come so soon.


 


4. X&Y gear ratio used to be 2:1.  From the beginning of 2020, Y axis gear ratio for Nova 35/51/63 was changed to 3:1, aiming to decrease the unsmooth cutting problem on big machine. (but increasing the gear ratio will sacrifice speed, so we still keep the X ratio 2:1).

 

 

5. Gradually from May, we changed some motor and driver to new models on Nova 51 and Nova 63, also aiming to improve the cutting smoothness. (but change also means unexpected problem, we would make more testing before fully replacing them).


So we are using two types of easy servo motors and drivers.

  1. Driver HBS57-500(V2.0), motor: 573HBM20-LS-1000
  2. New driver: CL1-507-3LS (grey color), New motor: 573HBM20-L-1000


 

 

Summary

  1. Z axis up/down buttons: from #20

 

  1. 3:1  Y axis gear ratio on Nova35/51/63: from the beginning of 2020.

 

  1. New Motor/driver:from all machines on #20;  Nova51 and Nova63 on #21, #22, and #23

 

  1. Chiller connected to machine:  Nova24 on #22,   Nova24 and Nova51 on #23

 

  1. drop tray:   only 3 machines on #23 have this feature as of now.  

Nova 35-80w, 2009390
