Solved White Screen on new Christmas present

Got a C2 for Christmas and cannot use the machine because the screen is just white. We've followed the suggestions in the video, pulling and reseating cables but nothing has worked. Have sent in a request to tech support but thought maybe someone might have another idea. Would really like to start printing !

 

Mine did that after about a month of printing... turned out that I corrupted the SD card in the Raspberry Pi. After I reloaded it, all was well again.

You can also check the HDMI connection inside the printer, but that’s probably not it.

Thanks for the replies. My dad got this at a local store for me for Christmas. Its was the last one in stock. I guess I'll have to wait for tech support. I wanted to start printing over Christmas break. Do you think they can help me that soon ?

 

We did try both ends of the HDMI cable too. That didn't work either. Could we plug it directly into our LAN with an ethernet cable and bypass the wireless connection ?

 

Partially solved. Tech support got back with us. They sent us a link for a new .img file We had to "flash" that to a micro SD card using a program they recommend called Etcher. Lucky we had a laptop with an SD port. We bought a new 16G card (all I could find) but they said we could have reflashed theirs (only requires 8G) Screen now comes up but we can't get it to connect to our wifi. It won't find any network at all. We're letting it run for a while as this software seems to take forever. Maybe it will find it eventually. One of our tries to juust access the Utilities menu took over 45 seconds to load. And I can't back out of any submenu without turning the machine off and on (and I'm using pencil eraser head as suggested on another string. Stylus doesn't work at all)

 

No wifi connect for an hour. Tried to set up a wifi hotspot, that failed as well

 

I'm going to mark this solved but it wasn't really. Unless you say my wife did it. My son is now up and working because of her. I'm writing this up so someone else won't go through the same misery we did. We haven't heard back from tech support (or anyone else I wrote at Robo) for a week now. The reinstall of the flash image got the screen up but it was working poorly and the machine would never connect to wifi. I was ready to just return it to the retailer (who seemed to have stopped carrying Robo) and buy a different product. My wife who worked in retail for years made one final effort and called the store manager. Short version, they are carrying the product again and they agreed to exchange the C2 for another one. We got it today and I have to say its like a completely different machine. My son had it up and running in 1/2 hr. The touch screen works, the wifi came right up and he has already got some of his designs printing. I can't stress enough the difference in the two printers. More than night and day if thats possible. I just hope the retailer doesn't try to sell it to someone else. If your product doesn't seem to work correctly out of the box, don't mess with it. Take it back. The old machine was so bad that even the original SD card was bad, not just a corrupt image. We tried to reflash that old card and it still didn't work. We only got it to come up after we bought a new micro SD card. I realize the tech support folks have likely been busy with the holidays but they've completely ignored us for a week. Disappointing. Lets hope thats the last of those kinds of issues.

 

Agree about the card location. It was a challenge even to figure out exactly where it was. Can't even see the slot when you put it back. Gotta go by "feel". We kept the "new" image/SD card and put the old corrupt one back in the machine we returned. I presume if anything happens to the new machine we can put this saved image in to get it back up. Gotta do some research on how to save the any updated image files. Turns out having wifi turned on wouldn't have helped us with the old machine. We don't have an Apple product in the house. The apparently don't have the Android version available yet. Didn't know that until today. But this new touch screen works well so not an issue at this point. Thanks for your support Mark. And the encouragement Fitz and Geof. One new problem. I think the boy is going to be up until 4A tinkering....

 

@Icthys Welcome to the forums (and glad to see that you're up and working finally).

If you're into coding, check out my own Robo mobile app which should work fine for an Android phone as long as you're on the same network. (The install instructions assumed OSX but replacing the forward slashes with backslashes should work for a PC.) Robo 3D themselves may have their Android app available soon enough from what I understand.

Minimum requirements: git and npm

I've got a number of Robo C2 mods in my repository, for what it's worth.

 

Dad here. Just thought I'd give you guys a one month in report since you were so much help. He's gone through 1 1/2K of PLA already, maybe closer to 2K Customized it with the fan shroud and his own design nozel cover with his name instead of Robo. So he's having fun. We just bought some PLA from both the local Microcenter and from Push Plastics to compare. Thanks a lot for all of the help. Robo sent him a complimentary spool of Glow in the Dark for all issues. That was a nice touch.

 

Coolness.

You might want to check for any caution labels on the Glow-in-the-Dark filament. I've heard anecdotes of some of those causing faster-than-usual nozzle wear.
