Geeetech

Hi all,

I've had a geeetech printer standing idle for a few years, went to power it up the other day and I had 2 lines of blocks on the LCD screen flash up, vanish for 10 seconds or so, flash up again and so on. If I unplug the usb lead to my pc, this doesn't happen, only when I'm hooked up to my pc. If I run my repetier host software, I can connect to my printer but the connection is lost when the 2 lines pop up onto the LCD screen on the printer. On the repetier software, there are lines at the bottom where instructions and feedback can be seen, that comes up as random letters/digits, like it's corrupt.

I tried to reflash the software to my gt2560 board and the Arduino software said that port 8 was in use, stop what ever was using it to continue, my 3d printer is on port 8, so I am stuck, can anyone offer any suggestions please?

I am pretty new to 3d printing, when I got the printer, I read through software installation instructions and updated it all ok, building the actual printer was easy enough, I can't code at all.

Prior to this, a few years ago, I was printing things fine.

The board is a GT2560 rev a, I have i3 Pro B software that was uploaded via the Arduino 101 software, the printer was from Amazon, single head, my pc is running windoze 7 enterprise, stupid amounts of processor and RAM etc.

Hi, I think you can try to print without connecting to the computer to verify that the printer is normal. Maybe the problem with the port is that you can't connect.

I've setup an old laptop, same O/S etc, bunged on the repetier software I use, got Cura on as well, all seems to work ok, so obviously an issue with my main pc, not tried printing as yet but nothing to say it won't print. Got to make sure all ok, bed level blah blah blah
