More great info - thank you

well I have the LinuxCNC CD burned and been into the live version to check latency which seems ok. time to swap HDD and do an install and see how it works....

as I have both a lathe and mill to control UCCNC not having a turn component is a bit of a showstopper for me. I know its in the works but I also appreciate there is no timeline and it may never happen so for now it looks like Mach3 or LinuxCNC are the options - I would rather spend the time familiarising on a single control option rather than using 2 different ones as the potential for human error switching between them is high - its easy to forget lol

while I like the comfy Windows environment its not like this PC will be doing anything other than machine control so Linux may not be so bad...

getting any motion control in the UK seems to be difficult and while I have licenced Mach3 it came with the mill so its not like I have invested in it and I have to learn it as well.

I probably have a few weeks of messing around to figure things out before I make the purchase so any and all feedback is great. so many options!
