Hello all,
We are students at UIUC. Currently we are installing the software and the system of my computer is Win 8.1. Problems are below:
1.The SD card is failed even though we did nothing and we tried to read it in computer and it was fine (in picture 2) I personally think our LCD panel does not work since the light did not tureen on when it was powered.
2. The thermistor on the heat bed is defect.(We installed it as the steps in your instruction but it was not connected to any wire like the one on the heat rod), so was it normal? (picture 3)
3.The printer set into dry run mode until restart. (We don't know what it means and should or how to change the setting? Picture 3)
4.I would be very appreciated if anyone can tell us the best version of softwares we should use. Thanks a lot!
Looking forward to receive your answer!

Re: RosTock Max Version 1
Not all SD cards work with arduino based electronics like the Rambo used by the Max.
You need one that supports the SPI interface, unfortunately they don't list this on the box's I can tell you most of the small <4GB San disk cards work and none of the Kingston ones I've tried do. There is a partial list of working cards on the Reprap wiki.
Having said that if you don't have any power to the LCD Panel it's more likely it's wired incorrectly or broken, I'd err on the side of the former, on a V1 wiring it was very easy to mess up.
The Dry run mode will happen if either thermistor reads out of range, I'm assuming it's the heated bed one, you need to trouble shoot why you get no reading, start by measuring the resistance of the thermistor at the RAMBO connector (when disconnected from the RAMBO) and trace the the wiring back to the thermistor, there is probably a bad connection or a short somewhere. Unless you pull a leg off the thermistor they are pretty robust devices.
When you resolve the other issues, you'll want to upgrade the firmware to the latest version on the SeeMe site, 0.8 has some fairly serious know bugs, there are some changes that need to be made when configuring 0.9X for a V1, so I'd get it printing with 0.8 first.

Re: RosTock Max Version 1
Thank you very much for your reply. For question 2, in the instruction, the two legs of the thermistor is not connected to any wire like the one of the heat rod and that was what I guessed why it was defected. Would you mind telling me about installing this? Thank you very much!
Re: RosTock Max Version 1
The instructions are pretty clear on how the thermistor is wired in. Were you the one to build the machine?
"SD Init Fail" will appear when the firmware can't see the SD card - if there's no SD card inserted, you'll get that message, but I think you need to figure out why the LCD panel isn't working first.

Re: RosTock Max Version 1
My experience with the LCD building my V1 was similar. It is very easy to connect the LCD panel in a way that does not function. I had to go back and look at diagrams several times to get it right.
For the thermistor, I agree with starting at the board measuring resistance. If it reads low, you've got a short, high and something isn't connected that should be. You can always verify it's operation by hooking your meter to it and heating it by holding your finger to it. The resistance should change.

Re: RosTock Max Version 1
Thank you all for helping us out, I think we have found a way to solve the problem. But for the coding of Arduino, it always says error, can you guys help me out with this part?
Re: RosTock Max Version 1
Can you be more specific? What are you trying to do when you get the error? What is the error message?fuhao1995323 wrote:Thank you all for helping us out, I think we have found a way to solve the problem. But for the coding of Arduino, it always says error, can you guys help me out with this part?
