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

Been very busy with work so been restricted when I can play with the machine, I have been plodding along in the back ground though. I have no fully re wired the stepper motors to the controller, I have binned the cheap 5 core unscreened power cables for a thicker screened 5 core cable and freshly soldered them to the plugs. These were a complete nightmare to try and fish through the cable track but I got there in the end. Once wired up the motors were making a high pitch noise, also when trying to jog any of the axis they just seemed to move back and fourth which is a tell tale sign of the wrong core pairs being wired up. For anyone interested, my motors are 4 cable motors, which means it has 2 coils with 1 pair of cables per coil. I used the multimetre to find when 2 of the cables were connected a circuit was made, that way I could establish which cables were paired together. The I wired one pair to pins 1 and 2, and the other to 4 and 5 of the 5 pin plug and hey presto it worked well. I have made the length of the cables just shy of 3m for now as im making a full enclosure so thought it is much easier to cut the cables back than to add in AND RE-FISH THROUGH THE CABLE TRACK LOL

Anyway here is a few pics, limit switches are to be done tonight then I can start setting the controller up through the software which I really have no idea how to do but got plenty of literature from Planet CNC to guide me, would like to mention they have been very supportive throughout this build even though I have been bombarding them with daft question constantly.
