I get a similar error.

I have a 3-in-1 controller box with the GT2560 control board in it. I've been using the printer (Repetier and Slic3r) )with no problems for over 2 years. All of a sudden, as of 3 days ago, I get the problem: printer just stops in the middle of a print. Sometimes it happens ...

I put a scope on the IC1 hex buffer clock pin 3, and when I inserted a card, I got a brief clock signal, but it had a ghost/reflection, probably enough to prevent the SD card from working. I thought maybe the trigger on my scope wasnt set right, but then I remembered from somewhere that impedance ...

Out of desperation I re-soldered the pins in IC1 (even though they looked OK).

The SD card slot now works great. All my SD cards work: 512MB SD, 2GB SD, 4GB SDHC Class 4, 8GB SDHC Class 10

I tried .gco, .gcode. In either case the SD card cant be seen, although it does know the card has been inserted.

Soldering looks OK, I dont see any bad joints or shorts.

I've tried 3 cards so far, all the same result: No SD Card, and echo: SD Init Fail

That's why I wonder if maybe it's something ...

Hi Mark,

The heatbed measures 1.4 ohms across the red wires, cold.

When set to 115C in Repetier (as measured by the built-in thermistor), the aluminum bed itself only goes to 75C, as measured with a thermocouple. That's as hot as it goes, ie setting Repetier to 117C results in no additional ...

Hi,

I have 3-in-1 control box and can't seem to get my SD card reader to work.

When I insert SD card the display shows Card Inserted, then when I scroll down it says No SD Card and I cannot see any files on the card.

I've tried several different SD cards, different format (FAT16, FAT32 ...

Hi,

I have the 3-in-1 control box. With the power supply outputting 12 volts, I measure 11.5 volts across the heatbed terminals when it is on. Can I turn up the voltage from the power supply a little? Say to 13 volts?

The reason is that my heatbed temp seems a little low.

The GT2560 ...
