I'm just finishing a retrofit of a Triac. Used Acorn Centroid.

Previously I've used SZGH, CS LABS, Pokeys and various hardware on Mach 3 and Mach 4. I think I have a fair sense of what each offers.

I've skipped LinuxCNC. Familiar with Linux, its used widely in my IRL industry.

There are 2 systems catching my eye at the moment and I'm looking at a retrofit on a 5 Axis mill that I have recently bought which still uses an old Heidenhain TNC 407 controller.

The first is the Masso G5 Touch. It looks amazing, very professional and relatively simple to use. I do like the 'no PC' option. With SZGH for example, no PC, great, however not. Moving files onto it is a pain etc whereas Masso has an eco system for wifi / remote management etc. The downside, its expensive and there's little support. They have a forum, its not very active.

The 2nd is one of the older systems which Ive previously not looked at an that's UCCNC and the various controller boards. I avoided this mostly as I didnt want a less supported Mach 3 clone. That said, it may have been wrong. It looks decent, has great support. The various hardware is relatively affordable.

I do like Centroid. I'm struggling a bit with some PLC / Code for the Triac's ATC but will get there ... The 6 Axis Centroid card is expensive, so willing to look at the Masso but its really pricy. Do I save £1K and go for the UNCNC ecosystem?

This is a 5 Axis Bridgeport clone (Gate) machine with an A and C axis (Nikken).

Thanks.
