CNCdrive UC300ETH Mach3 plugin is now available

Don't understand why folks will buy Motion controller for the higher cleaner pulse rates then strangle them by connecting to Cheap BOB with Slow Optos etc.?

Nobody prevents you from buying a super expensive BOB and use that if you want to and believe it can do better. The BOB I have can pulse fast enough. Besides, the problem is NOT the optos on the inputs but the optos in the stepper driver. If you have crappy driver you have problems, yes, but the pulsing from the motion controller or the cheap BOB is not the problem, the problem is your driver in that case.

Here is a video I just made. My CNC is using the cheap BOBs and the UCCNC with the UC300ETH in this one.



I have also made a similar test with Mach3 and I can't run Mach3 as fast as I can run UCCNC with otherwise everything being the same. Mach3 can't keep up with the acceleration/deceleration, and that's not the fault of the optos in the BOB but Mach3.
