I may as well stick my bit in as well, Hood used me as a test case for his purchase convincing me I needed one of these, the man is an evil genius

I have 2 of these units now a 4 axis CSMIO/IP-M and the new and just released 6 axis +/-10v analogue CSMIO/IP-A
The 4 axis is fitted to a mini mill and has worked without a hitch for several months now, the installation was quick and easy as the mill is a very basic stepper driven 3 axis wired for a 4th when needed, home switches and a 0-10v spindle drive. It runs off a ASRock PV530A-ITX 1.8Ghz Mini-ITX Mainboard with 2 Gb ram and a 30Gb solid state drive and WinXP the whole lot was less than 100 quid and it works very well.
The CSMIO/IP-A 6 axis unit is fitted to a 4 axis mill with Baldor Flex drives working +/-10v with 4096 pulse encoder feed back, I have to say the documentation is somewhat lacking at the moment so installation of the software was a bit confusing on a clean install of windows, I am informed the manuals are been worked on as is the automatic installation of the software and new versions are due very soon. The team at CS_Labs have been very helpful and are very keen to get things right.
The unit is now installed and controlling the XY & Z axis the motion is very smooth and very accurate, the servo tuning is manual at the moment so it was pot luck as to just how good I got the motion, there is an auto tune feature in the setup screen but this is not working at the moment, again a new plugin is due soon with the auto tune working. At the moment its running off my old Dell laptop but I will be installing the same PC as the mini mill.
All in all I only have good things to say about the controllers and the company, I have just ordered a MPG unit to go on this machine too.
