Hi. This is the procedure I followed.
- Image a microSD card with the latest downloadable version (v0.10(4) ).
- Put the card in a Pi3, and run the sudo apt-get update, sudo apt-get upgrade and sudo apt-get distro-upgrade commands via SSH to ensure latest kernel etc.
- Manually configure the wifi using the instructions from @Daniel at this link
- To get the pi camera working with Astroprint enable the camera first in raspi-config and then usual setup in Astroprint.
I assume all the above could also be done directly on the zeroW if you have a microUSB to ethernet setup.
