All good points. A few i'll touch on. In case you're wondering about fans, how's this look? Calibration with the probe on Rostocks seems to be working much better. I wish i had a more scientific answer other than "longer arms maybe?" or something along those lines, but the bigger more rigid machine does tend to ring the accelorometer cleaner. It is what it is. That's not to say we havn't fixed things on the ERIS and it probes much better now.
Raspi support has always been there, it's just now we're pushing it more and more for the mass of users that want the wifi control or networked control of their printers. The touch tablets do that to some extent, but just not to the same extent that the pi setups with astro/octoprint can and have done.
Chassis cooling is the same 60mm fan as the ERIS, but it's mounted a little different, and as such it's much quieter. The ERIS has a lot of stuff going on in that little tiny package, and needs a lot of airflow to keep things under control

Yes, RAMBo is what we have always used. Reliability trumps cutting edge when you have as many users building for the first time as we do. Yes, 32b ala smoothie etc. has a lot of advantages, but theres just not nearly as big of a user base and it's not being actively developed fast enough to where we would need it to be to include it in our kits. Now again, that said

Lastly, go check out the site guys, they're up for pre-order now. Just loaded them up. And if you're reading this, and want one, or know of someone wanting one, use this or give them this code v3forme one per
Have fun guys, hope you enjoy it!
