PI evaluation cumbersome
First of I love the interface, the idea and the implementation.
Currently using Octoprint with reasonable success but I find the octoprint interface (especially the touchui) a little too user unfriendly especially for smaller touch screens (like the 3.5 adafruit one I have).
So I downloaded the Pi version of Repetier Server, flashed it to an 8gb card ... and it wouldn't even boot. Mind you I blame that one on the card. It's an old and slow card.
Then flashed it to a 32gb Lexor card, and it boots but no wifi showed up after 10 minutes so I decided to go move the pi (I use wireless because I have no network cables at it's normal location) upstairs and connect it to an ethernet cable. This worked. I started the trial went through a WLAN config. Installed the Adafruit display drivers (it's not HDMI but connected to GPIO) and admittedly messed up there by selecting the mirror HDMI option (this usually results in a scaled display mode with the touchscreen input not matching the screen). The PI reboots then and as expected the repetier UI appeared.
This is when it all went to hell in a handbasket. For some reason my Wifi router (and internet cable modem) suddenly started using a completely different address range. I assume it sensed an IP conflict and thus started using a different range to compensate. As the only thing going on at the time was me configuring repetier on the Pi I suspect both the modem and Pi were in conflict (not sure why)?
Worst of all the Repetier UI complained about needing a license but due to my own mistake I could not use the Touchscreen to try and fix it on the Pi directly. Of course with the modem and Pi also seemingly in conflict over IP ranges getting to the Pi remotely was also out of the question. Your basic catch 22 scenario it seems.
I guess my point is that having to struggle with both the experimental nature of something like a Raspberry PI and a licensing mechanism is a bit much.
I am not saying remove licensing, just make it so it is not an additional issue to have to deal with while you are trying to get the basics (i.e. the PI) running if that makes any sense.
