SD card problem

[Tintek]

Hy!

I buy one of your printer prusa i3 pro B2 from ebay.de

It works more than good, i realy did not expected as much from it.

But there is one problem it works only online from computer, if i just pust the button on lcd the printer freeze and can't eaven connect with the PC. Even if i pust one or other reset button not helped, lcd just show two line on lcd.
Only solution is that i disconect the SD flat cable, than i can reset it.

I try to upload new FW for a few times but nothing, i checked al the circuit, all the connector and cable, but can't find the problem.

Also try many different SD card with different format...

What can i do to print without PC?

Thanks Tine

Did you try other ports on your PC or change another USB cable?

Why? I said that works great with pc and usb connection, there is problem with sdcard or offline mode, if i do not heave connected usb cable at all and just push the knob and try to go down it freeze and can't be reset.

So the socket direction is the exact problem?

[Tintek]

Yes, some guy solder it on wrong way, i don't want to desolder it and solder again, so just cut another hole on other side and turn the connector for 180 degree, it works now, thanks
