just bought GcodePrintr v.2.52 and installed on my tablet Samsung T-705.
When I connect my printer via OTG cable the programs starts by itself, but when I press ‘connect’ the answer is:
Request access to USB device. VendorID 0x1a86 ProductID:0x7523 Device:/dev/bus/usb/002/011
Connecting to serial port (250000 baud)
Connection to printer failed
(Please send… by email ecc.)
My board is an ATmega 2560 + RAMPS 1.4, CH340/341 Serial/USB chip.
Thanks in advance
