DDSCV1.1 3 and 4 axis offline motion controller

but I'll still keep running my little probing machine on Mach 3, just for the Probe-It probing plugin.

I believe that the author of the Probe It is porting it to UCCNC.

Not much use to me though, as my probing machine runs a KFlop+KStep with linear scales to close the loop, to get as much accuracy as possible. :-/

Ger, do you happen to know the Macro/program refresh rate for the UCNC software?
I know Mach3 is 10Hz, Mach 4 is fair bit quicker but depends on system load, and KFlop depends entirely on how you program it but can potentially be 90uS.

UCCNC has 48 macroloops, which are similar to mach3's macropump. These apparently run independently, and can be any speed you want. There's an example in the manual for running at 20Hz. Apparently, the faster they run, the higher the CPU loading?
They don't mention the screen refresh, but it's independent of the macros, and appears to be much faster than mach3, as the DRO's are much smoother. The toolpath display is different, so hard to compare. But the entire interface seems much faster.

Thanks for that Gerry. I did have a quick look through the UCNC manual, but couldn't find anything, and a quick search of the forum mentioned a macro manual which I couldn't find a download link to. It was how quick macros could update inputs/outputs I was interested in. As long as the screen can tell me what I need to know at a reasonable speed, I'm not that interested in just how quickly it updates.

I've not got any plans to use any of their controllers, but I still like to know what the limitations are for whenever any questions come up.

According to Ron everyone left the workshop with a working lathe but only one person has posted since then about their machine and that was to say that due to issues with Mach 4 he couldn't get his machine running and so far it still isn't running.

Not one person posted a video? and Ron will not show a finished thread?

A friend of mine has one of those lathes, but hasn't had time to use it. Last time I talked to him, he said there were still issues with the speed control due to either the Pokeys or the speed control board they are using, from CNC4PC I think?
