Machine story:

2014-09-18
Foam residue, comming from the noise isolation, placed on the bottom plate and case interside, is found in the machine.
The plus and minus key are both pushed in .

2014-09-20
Cleaned the machine mechanics; case and bottom plate and remove the foam residue.
The machine sprayed with W40 to make hardened oil, fluid and lubricate again.
The machine seem not blocked. A machine cycle could be finished ( operate manually) by turning the main axis. Turn the electricity on a plus cycle performed. It seem to run two times?? But on this moment enough to know that it runs on motor. How well is of later matter.
