We have 3 Multus machines and they are the worst CNC machines we have encountered. Un-user-friendly, always breaking down, known problematic issues, slide covers that break after just 2 years and have to be replaced at $10k per machine, throwing tools out etc etc. We have a Macturn bought new in 2012 and it took Okuma almost 1 year to get it working and even then it runs for only a short time then something goes wrong. Its a piece of junk.
If you want big troubles with a new machine buy a Multus. If you want something reliable look elsewhere.
Of course the Okuma fanboys will have another point of view but if you search here for Okuma Multus problem posts you will read the truth.
There are many posts about Okuma problems. You can read some here......
