Cleaning ETMX vacuum dirty window |
|

Gautom is progressing with the layout nicely. The X-arm transmission window have not seen cleaning for decades. This should be the time to do it. Here is picture of dirtiness.
It is not that simple... How much effort should we put in it? The hole table with 1W inno laser plus... set up now about ~500 lbs We can pull it off carefully, but it is not risk free.
We should look at our other signal port windows! Gautom's long reach able him to do the first contact cleaning without moving anything. It is great!
