Answered ROBO 3D R1+ Cant Connect Over USB

Hello

So I've had this printer for over a year now and its been running great and I've never encountered any connection issues till today. I got a new computer and I went to plug in the printer and I'm not receiving any signal from the printer itself. I checked the device manager and I got nothing on the COM's. I also tried plugging it in to my old computer that I used to run it on and I got the same issue. No COM's on device manager. And just to be sure it wasn't a cable issue, I tried 3 different cables and all 3 cable worked with other devices. Am I looking at a bad arduino board?

 

I just tried installing new Arduino Drivers on my new computer but to no avail. I'm going to try the same on the old computer.

 

I'm thinking that I have a bad board. I tried installing new drivers on two computers and I don't even get a notification sound when I plug in the printer. I'm also getting no readings on any COM ports in the Device Manager on both computers.

 

I removed the cover and I dont see any visual damage although I didn't take off the top section of the board with all the headers and connections. Every looks and sounds like its running (lights and fans are running), I'm just getting no comms from the board.

I'm assuming the top section is the RAMPS shield. If that's the case, I can take that off to visually inspect the board below

 

Okay. I think I ruled out the computer since the printer isn't working on my old computer and it was running flawlessly on that for 6 months. I tried different cables, drivers, and computers and none of that helped. I think I might just end up swapping out the board. Nonetheless, thank you both for your speedy input.

 

Sounds good. I'll see if that works. If not, I'll replace the board. If it's the latter where are the best places to buy from for a replacement? And what does replacing it all entail? Is it a simple swap out our do I need to flash the new board with anything?
