Hello,
I am new with SmoothieBoard and I have a “serious” problem.
Fist off all, I use:
Windows 7, CamBam to produce gcode, Pronterface, the last firmware, config and windows usb drivers for the SmoothieBoard.
I have create with CamBam a gcode with 450 lines. The size of the file is 9.700 bytes. My next step is to load the gcode to smoothieboard via the PronterFace. But, the SmoothieBoard stops after some lines of gcode. It doesn’t stop at the same line every time. The maximum progress that I have done are 98 lines. When I plugin the usb cable to my laptop the leds 2 and 3 blinks.
What I have tried up to now:
with new sd card,
to mount and unmount the sd card (manually),
via command play (play /sd/file -v)
with different file extension, file.gcode - file.nc
with different baud rates
When SmoothieBoard stops the situation of leds 2 and 3 is not every time the same. Some times:
both leds blink, or
led 2 is stable and 3 blinks, and some times
led 2 is stable and led 3 is off.
Could I load the gcode directly to sd card without Pronterface and how?
Could you suggest me something else?
Regards,
Giannis

I am having a similar issue with Smoothie. I have had 2 large prints fail this week. I have had failures before that I traced to my computer, but these both occurred while printing directly from the sd card with no computer attached. It appears that the board resets and doesn’t just stop because all leds are normal and the heaters are off but everything is stopped. These are long prints, supposed to be 24 hours. One stopped after 12 hours and the second stopped around 16 hours.
Your issue may be something with your computer so disconnecting it during printing may help your situation.
To print from the SD card, just type sdprint from the console and select your file on the sdcard. After the print starts you can disconnect your computer. Put the gcode file on the sd card however you want. I just copy mine through windows over the USB and unmount (eject) the card.
I’ve also had this problem and found two causes:
1 - A problem with the USB connection. This happened twice - one time the USB cable got jiggled at the computer - I reconnected it and it continued - even though it was printing from SD. I recommend disconnecting the USB cable from your computer after starting a long job.
2 - Crosstalk between the stepper wires and another wire. I use three external stepper drivers for my 3D printer, and am using one on-board stepper driver for the extruder.
I had added an external reset button, and the two wires were right next to the extruder’s stepper wires - crossing at 90 degrees. During a long print it would reset or hang the Smoothie. Testing just extruding at high speed would do the same thing. I moved the reset wires away from the stepper wires and it was cured. I had shielded all the other stepper wires except that one… I recommend keeping all other wiring away from the stepper wires.
