My Cheapo Chineese 3020t mini CNC Build (more like improvements) leanring all the way

here is a pic of the soldering I did, the limit switch plugs are on the bottom.

I cant see anything obviously wrong from the picture, to check the back of it would mean removing all the soldering to allow it to separate. Am I correct in understanding that I could program the end socket to act as the y axis input if it works?

Just an idea
