I bought the ready-made one - $149. I was looking at the kit on Adafruit for $75, but they were sold out and I think the processor is better on the ready-made Astrobox. Anyways, I was having some software issues and just tried using the Astrobox webpage, and it seems to work fine. I couldn't get the bed to heat at first, but preheated it manually using the controls on the front of the printer, and now the bed control seems to work on the Astrobox browser - early days so I am not sure.
My first print looked good for the first half and then slid off of its spot, so failed. I have now preheated the bed (didn't use heat on the bed for the first print) and installed the acrylic cover. We will see how this one does!
