HEXAGON DEA CMM loses its home position

Hello, everyone!
Nowadays I am working with HEXAGON Dea and during last 3 weeks I started to notice, that sometimes, after switching on a new program, CMM goes into emergency mode. After pressing Motor On it does't give the opportunity to work, due to the fact that it loses its own home position. For example, on the position, where X has to be 0, it shows- minus 5238.93849303232. So, because of that it is impossible to calibrate or to work with machine in such condition. To switch off machine for night used to help, but nowadays this problem starts to appear more often and it becomes worse and worse.
UPD: Unfortunately cleaning of scales didn't help to solve the problem. Machine still loses its home position (I forgot to say, only in X direction). It has 3 legs on both sides, so if to imagine that zero position is near the 3rd leg, now it goes in between the 1st and the 2nd legs, stops there and switches "Emergency stop" in controller box (quite loud sound). The code of mistake is " Level 3: Axis X error (0x34) Please Reset Emergency".
My questions are- what can be the main problem and how to solve it?
Thank you

  • Hello, everyone!
    Just in case if somebody is interested why such problem appeared: The problem was in air pressure , in usual condition it is a bit below 0.2(something like 0.195). But when I checked- the pressure was 0.17. After I increased it to 0.2, and while moving on Z-axis it started moving quite sharply(jumping), but computer got normal coordinates and PC-DMIS found its own home position. Then I decreased pressure a bit, tip started moving smoothly and everything started working normally.
    Hope it was not just an usual luck, because in this case problem is not solved and will apper again.
