So I'm really pretty happy with my Robo R1 + except lack of support. I had a problem with my SD card reader not working right out of the box. I called Robo and they were going to send me a new Arduino board, but needed me to send an email. I did that and NEVER heard back from them. I bought one after market myself and a Ramps 1.4. That solved my problem, but I shouldn't have had to do this. I keep seeing all of these troubleshooting posts where people are looking for parts. I've never purchased a product where I couldn't go to the companies website and purchase replacement parts. You can't with Robo. I'm thinking about buying another printer and really hesitate because of this experience. It feels like you buy this item and you're kind of on your own. The guys in the forum are tremendously helpful and that's Robo's only saving grace, but I really think Robo needs to correct this to be a serious contender in the 3D industry. I've been surfing other sites with quality printers and they DO offer pretty much all wear and tear parts to order. Any opinions on this? I've heard mixed reviews on service, but my own has not been good.
