Xrd holder cleaner

I will handle retrofitting the 3d printer. Last week I designed and printed a toolhead to mount the vacuum hose to the 3d printer. Will move forward with this next week!

The robot is ready now. Once the vacuum switch is ready we can install this in 105

Vacuum switch is ready. Both robot and switch are on the tall table in 105.

Sometimes, vacuuming alone is insufficient to remove all powder from the XRD holder. This even differs across replicates of the same powder. Maybe some hygroscopic powders stick to the holder when they are left in air for longer? Anyways, we need to account for this.

I suggest using a camera to take pics of the holder after cleaning:

• If clean enough, return the holder to the rack and mark as CLEAN
• If too dirty, still return to rack but mark as DIRTY. This spawns a userrequest for manual cleaning, basically same behavior as XRD cleaning now without the robot. If all XRD holders are DIRTY, the system will hang until user cleans a holder.

To start can we use the robot arm camera?
