Printing from SD card will not work for me.

[Nofear202]

I am following the Simplify3D traffic cone example and did all the steps. Now when I try to print from my SD card nothing happens? I noticed in my communication tab that it said "RECEIVED: echo:SD init fail
SD init fail". So what does that mean?

Thanks

It's your printer telling your computer that the firmware on your printer has failed to initialize the SD Card reader on the printer. This usually happens when you connect to the printer without an SD card in the printer. It shouldn't affect anything, and once you put an SD card into the reader, and send a initialzing request (this is done automatically when you try to read or write to the SD card in the printer) it should work fine

Ok so what do I do? I have the SD card in my printer, before I turn it on. Now I don't even see the g-code file? In the g-code tab.

Do you see the gcode files when you plug it in to your computer? Maybe you need to format the SD card so that it uses a FAT16 filesystem. Some of the larger cards also aren't compatible, so generally I have better luck using SDHC with 4GB or less in size

With G-Code files loaded onto the SD Card, go to the Machine Control Panel (Tools > Machine Control Panel) and then click the button "Print From SD" and it should bring up a pop-up with all the found gcode files on your SD Card.

I know the wanhao D4 firmware has an issue. I flashed mine to sailfish 7.7 and the SD card worked.

Ok It finally sees the G-Code up on my Simplify3D G-code library tab. I don't know why its now working I didn't do anything different? But anyways now I get this pop up window saying " Unable to open the selected file. Has it been moved or deleted?".
How did it get deleted or moved when I just saved it to my SD Card?
I don't get it, even Simplify3D program sees it in the G-code tab?

Thanks

Files appearing in the "G-Code Library" are locally saved G-Code files, not ones located on your printer's SD Card. Printing from the G-Code library will open up a file for printing and stream it over USB to your printer, the same way the "Print over USB" button works. You're getting the message because you saved the gcode file onto the SD Card that you plugged into your computer, and once you take it out to put into your printer, the SD card is no longer "local" and the file is no longer in your computer. With the SD card inserted into your printer, use the Print From SD card button in the Machine Control Panel. It will open up a window containing all the gcode files on the sd card, select the file you want to print, then hit ok. Your printer will begin to heat up and should begin printing shortly. Take a look at the communication tab/temperature tab to see preheat progress.

Ok I did what you said I left the SD card in my computer. Then I went to simplify3D controls and selected print from SD card. Nothing pops up?
I looked in the communications tab and got this.

That means the board can't read your SD card. There are many possible causes. A bad reader, incorrect wiring, wrong format on the card, incompatible card, firmware configured incorrectly, and I'm sure several others.
