Arduino Mega 2560 destroyed in attempt to do something even young eyes and steady nerves shouldn't probably attempt

Confirmed that the direction pin was not getting a signal for the y motor, it remained 0 while I saw that the x direction pin would be 0 or +5 depending on direction. Instead of just remapping the y direction and moving the connection to a remapped pin, I stupidly try to see if I can remove a solder bridge I am not even sure if I can see. The result is massive solder bridging over many pins and then after giving up and trying again, managed to pull up a trace because of repeated heating and scraping with soldering iron. So that will be another $17 or so dollars to get a new one from Ebay. Disgusted with myself but I will persevere after I can get the money from my wife.
