After much searching on the web and CnCZone I was unable to find the Pros and Cons of rigid/flex coupling.
Wikipedia says that "Flexible couplings are designed to transmit torque while permitting some radial and axial and angular misalignment". But what is meant by "misalignment". I would think that the rigid coupling would provide more accuracy. Is the error introduced by a flex coupling negligible or is it just accounted for in software.
The mechanics of CNC always get me stumped, seeing how I am a computer engineer, microelectronics are more my area.
Thanks in advance …
