Hi Mike its nice to hear that you are finally up and running!
You can calculate the powder like this:
You need 1 cm for every 100 layers (0.1mm layer high is standard) Also you will need additional 2 cm. 1 cm is for bed preparation and 1 cm is for cool-down. Also i suggest you put 5 mm to 1 cm more just to be sure.
So for the calibration print (5 mm) you will end up with about 3 cm space you need in the build chamber
For the feeding chamber this is a different story. you have to keep in mind that the density of the powder chances when sintering. From about 0.5 kg per liter to about 0.9 to 1 kg per liter (depending on the sintering strength). This means that you actually have to apply more powder to compensate. This means the feeding chamber will move about +25% the distance of the building chamber.
If you apply that knowledge to the calibration part you end up with 37.5 mm.
have fun printing if there are any more questions feel free to ask.
