Hi im tryin to use SD ramps, im enabled it in marlin. the software pronterface can pick up the sd card and read the file. when i click on the file it loads the file and starts printing. however when i press the disconnect or pull out the cable from the pc it stops printing. the led is on on the arduino when i plug out the usb and the D1 and D2 is installed on the ramps.
Does anyone know where im going wrong.
Im naming the files test.gco this is ok isnt it?
thanks
Hi,
If you are still having this problem, I might be able to help. You need to pull out the little jumper between the 2 chips. This will enable your reprap to run without input from the pc.
You will see it in the pic inside the yellow box.
When you do this, the ramps gets power from your power supply also. So the red led will not come on and you cannot connect to your printer until you turn on your power.
Also if you send the gcode from pronterface it will take forever. Instead save it on the micro sd card in your computer and then plug that into your printer.
Let me know how you go.
