Hi
When I turn on my printer the LCD just displays black squares. I’ve been speaking to Geeetech support who suggested I update the firmware.
I’ve connected my laptop (ubuntu) to the printer using the USB and have tried to load the firmware using Arduino 1.0.1. but I get the following message
avrdude: stk500v2_ReceiveMessage(): timeout
Which I understand means that my laptop is having problems communicating with the board on my printer.
Any ideas ?
