Hi all
there must be some typos wrong the motors are nema 23 4NM
this machine has dual 20mm ball screws the motors are more than powerful to power these personally i would not move up the the 34s as there are inherent resonance issues & problems with acceleration & deceleration as well as the other problems stated in previous post that's not putting the 34s down they are good motors but not needed on this machine our competitors use only 3nm & lower in some cases our are 4NM motors powered & high voltage
RE the bed once the bed is ready for skimming the bed is 34mm thick there will be no discernible flex issues.
