Guys, It's a brilliant idea in concept. Although I'm still excited about the possibilities, out-of-box this still has some things which could have been avoided to make this a more mature product. I have yet to print anything on this and I've just spent $900. 1) First things first, the power switch on the back is wired so that 1=OFF and 0=ON (reversed). 2) The foldout documentation suggests that I should download the "mobile Robo app" which can't be found on the Apps Store. Would suggest that you update the documentation to indicate that you should search for "Robo3D, LTD" if you hope to find it. 3) In the iOS app, the Getting Started goes to a video about the R1 model which is perhaps 30% pertinent in content at best. If a gluestick is required for adhesion and presumably its cost is cheap as compared to a support call, then why not include one in the kit with the tweezers? 4) At Frye's, the Drone Kit was positioned about six inches from the C2 and suggested by the salesperson so I said "yes". Only after opening the box does it mention that it wants the print bed at 55ºC (not possible on the C2 model). Would strongly suggest updating the Drone Kit to indicate that it's compatible with printers with a heated print bed like the R1. 5) Here on the website -> Support -> Support Room -> Language = English -> Printer = C2 -> Troubleshooting -> "Print not sticking to bed" -> basically, a 404 error since there are no troubleshooting landing pages. 6) The foldout documentation didn't suggest running the Z-adjust wizard before attempting to print. I watched the first attempt "air print" perhaps a full inch off the bed's desk. 7) Not to be too cynical but perhaps the first thing to teach the new user is how to cancel a submitted print job to avoid unnecessary waste. I've made at least ten attempts now and still no joy on this. It's a bit lost on the new user that one must tap on the job in order to see the logistics and to be able to then cancel it. You should consider adding this information to any help videos. 8) As mentioned by others, the LCD screen appears to be finnicky, requiring more pressure than I would normally press. 9) Someone on a forum (for a Robo C2 printer) suggested that they taped a piece of paper to the bed to assist with adhesion. When attempting this I found that the automatic bed-check step was confused by the difference in reflectivity of the paper and tried to "air print" again. 10) When entering the wifi password I found the onscreen keyboard to be super-small. I eventually was able to use something small/pointy to type in the letters. Not sure what to suggest on this. 11) The onscreen LCD has an Update feature which doesn't appear to work at all. It appears to have two sections (Features/Bugs) with hyphens as placeholders but no content otherwise. (It's as if someone was attempting to marry up a JSON response with a template and yet that conversation never occurred, resulting in a blank report.) Clicking the button yields some terse error message. 12) There appear to be places within the interface so that I could change the print speed or to adjust the extrusion speed. Selecting this option then gives me a blank field in which to type... something. What am I supposed to type here? And if I did, how would I return the setting back to its default if I don't know what that is? I have to assume that bed adhesion could happen if some settings are changed by the interface/documentation is seriously lacking at the moment. If I had purchased this online, waited several days for it to arrive only for it to act this way, I think I'd be a lot more frustrated at Robo. As it is, I waited three months researching my choices and thought that I'd made a good decision with the Robo C2. It would be a shame to have to take this back to Frye's for a refund but I'm hoping that some sort of fix is possible. I've compromised back to simply attempting one of the Test files which came pre-installed on the printer. Neither of them are adhering to the bed. I'll go out and purchase a gluestick but I wanted someone there to address some of the issues I've listed and to offer some advice otherwise.
