Post Polargraph goes Up when I click Right

Hello there,

I'm very new to this, but I am nearly done with making my own polargraph, very excited!

The only problem is, for some reason when I click to the Right of the machine on the polargraphcontroller software, the pen moves Up instead. Similarly, when I click up, it goes right.

I've been trying to comb the forum to see if anyone has the same problem, but couldn't find any. Any suggestions would be greatly appreciated!

I am using an Arduino Uno, adafruit motor shield v2, most recent controller running through Processing, and mac.

Hi! This is a good one, I love diagnosing these ones.

When you say go RIGHT:
Left hand motor should turn clockwise, letting cord out.
Right hand motor should ALSO clockwise, pulling cord in.

When it goes UP instead:
Left hand motor is turning counter-clockwise, pulling cord in.
Right hand motor is turning clockwise, also pulling cord in.

So maybe your left-hand motor has it's wiring backwards?
