Good morning
with my printer Delta G2S, new, barely mounted, I can not load the firmware. I think the problem is the lack of communication between the computer (windows 7 32) and the motherboard. When I plug the usb on to win control panel will add a 3 Com port (Com3 no Arduino 2560) that I think is to communicate with the printer and tells me that I FTDI drivers installed. When I open Arduino 1.6.6 and load the Marlin, the end of the compilation stops and tells me it can not load the motherboard.
I tried to change the drivers, as suggested in the Arduino Forum, with Arduino.inf but Os goes iin crash just insert usb.

Suggestions?

Thank you

what's the specific error info? have you select the correct board type? and how about use arduino1.0.1, the latest arduino version will always have those problems.

Solved!

In my computer there was a USB card reader which created problems with the opening of the com ports:

Now the problem is a 'else: when I run the scripts 3 (GO X43.3 Y-12 Z5)
and 4 (43.3 G0 X-12 Y-Z5) the X-axis is inverted., 3 becomes 4
  and 4 becomes 3
how do I fix?

" 4 (43.3 G0 X-12 Y-Z5)" what do you mean by this??

Sorry:

the scripts

3: GO X43.3 Y-12 Z5 go in GO -X43.3 Y-12 Z5
and

4: GO -X43.3 Y-12 Z5 go in GO X43.3 Y-12 Z5

they are inverted

I think the correct coordinates should be "G0 X43.3 Y-12 Z5" and "G0 X-43.3 Y-12 Z5", not "-x43.3".
And if you write the correct coordinates and it still behaves like this, then how's your motor direction? or did you plugged the X axis in the Y axis connector or the Z axis one?

The problem is that the printer prints a mirror image: what must be on the right is left and what should be left on the right.
If mold a keychain with my name, the name is reversed, mirrored
Crushing home Tuttle three axes move in the same direction so this is not to reverse the direction of the motors.

then you have wrongly connected the X axis to the Y axis connector, you need to interchange them.

Thank-you !

I've inverted X and Y!

Solved!
