I have been doing some upgrades to the Robo C2. Even though I made a backup after a few changes to the original image from the SD card, I would like a download of the original Raspberry Pi image they included on the factory load of the printer. Well three days later after contacting Robo 3D support still no answer. They did contact me after three days, but I still have not received an answer; not a yes or a no, just double talk, when I asked why I cannot get an image their answer was so vague I'm not sure if I still recieved a yes or no answer on an image download link, I’m not sure what the answer was. It was like talking to a politician, I was confused. Since Raspberry Pi is an open OS I do not understand what the problem is. Well I have had it after three days calling Robo support still not a defined answer. Solution: I am going to buy another Robo C2 and copy the SD card. Then I will return the Robo C2. Before returning it I will of course backup that factory image. I will then post the image of the original load so everyone will have access to it and they will not have to go through the crap I am going through right now. Now that is what I call an open system, something Robo 3d does not get the concept of OPEN! It is very simple if you develop on an Open Public OS system then Open means Open. Look forward to my image link post. I know some of you will say "no you cannot do that", well to bad I am going too. Open means Open end of story! If it is not on this forum, it will defiantly be another one.
