Hi,

Yes UCCNC is software like Mach 3 and one can use various controller cards like ESS Smoothstepper or CNCDRIVES own ones like ETH300.
This is incorrect...UCCNC software requires one of CNCDrives own motion controllers, the UC100,UC300,UC400 or ABXEE. UCCNC cannot run an Ethernet SmoothStepper.

CNCDrives do however have a Mach3 plugin and a Mach4 plugin. Thus you could use a UC300 say with either Mach3, Mach4 or UCCNC.

For laser operations I would not recommend any of the CNCDrives with either variety of Mach, although the evidence is that they perform laser ops well with UCCNC.

If you are considering Mach then get Mach4 and an Ethernet Smoothstepper, laser ops on Mach3 are rudimentary at best. All development on Mach3 ceased seven years ago
and while still many use it it should be considered obsolete, it will stay exactly as it is now.
