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

many thanks neale, after all the grief I got about my soldering skills (or lack of) that was my first port of call but they all look fine. I think I have found the problem. I have tested all the pins against each other and found an inconsistency with limit plug no2. All the other tests on the other plugs behave the same but when I do the same test on the no 2 plug nothing happens. There doesnt seem to be a visible circuitry on the pcb so i am guessing this is enclosed within the pcb somehow? uploading a vid now

will be sending this info back to planet and hopefully get a new one sent out. This will give me a chance to finalise my wiring and get the earthing sorted. Just really motivated now thanks to you guys, getting the motors to work properly has really cheered me up.

possible when you were removing the solder you pulled up or otherwise damaged the copper trace around the hole... If so you should be able to see the trace in question, just scratch off the surface next to your solder blob and run solder to the trace. Alternatively you could run a small jumper wire or use a pcb repair pen.
