That looks like a great set of components. Proper Tamagawa resolvers and closed loop (to the controller) should give decent performance! And as you say, great value for money.

I have the 990MDCa (non absolute model, lower spec controller) that is also supplied by SZGH. However, mine came from Newker and I have to say it's been the very devil's own job trying to work out WTF their Chinglish manual was trying to say. It even got to the point where I machine translated the Chinese manual myself in desperation. Newker (and Newkye, different company) didn't seem to have anyone who could speak much better than their manuals were translated. I might have been better going with SZGH but I wasn't to know. In the end, I replaced it with an Acorn on my Shizuoka and moved the Newker onto my smaller Bridgeport machine. It's clearly quite a capable controller but has taken a lot of reverse engineering (aka trial and error) to figure out how to use some of the features. I had to rewrite the tool length offset and WCS measurement macros to get them to work on my machine and generate usable (English!) status messages.

I'm not sure exactly how these controllers came about. Newker, Newkye and SZGH are located in completely different parts of China yet physically their 990 models look identical. Note that the firmware is subtly different, so I can tell you that mistakenly reading one company's manual while trying to program another's controller doesn't end well and they aren't prepared to support each other's products(!). I paid about £300 for my 4 axis version when I was working in China but I don't think that saved me a lot of money in the end.

I'll be interested to see how this works out. In the meantime, I've taken a look at the 1000MDC manual and it is recognisable in general format but does at least look a bit more readable than what I was up against with the 990. However, there will still be some learning to be done while you get your head around how it is organised and what some of the Chinglish words actually mean. It's good to know you have a responsive team at SZGH - hopefully extending beyond the pre-sale period. This should be a fine machine when it's done!
