For those of you struggling with bed leveling, some advixe. Auto Bed Leveling is not a feature. It is a crutch. Better to address the root cause of the problem, and either replace the bed, or resurface it to be flat. You can do this by adding a sheet of glass of thickness between 3 and 5mm. Use silicone adhesive against the edges, but not under the glass.
Once you have a flat surface, do a three point manual leveling with the screws.

Not sure how reliable the sensor would be with a piece of glass that thick.

Glass does not have any electromagnetic properties. However if you put 5mm of glass on top with a sensor that takes readings at 4mm you may have problems. I would also assume printing on a flat surface (glass), but measure a warped one (aluminum bed), could be problematic as well. I have not tried the autobed leveling yet. I figured once I get my machined turned/level I should not have to adjust things. I am wanting to give it a try though. I plan to glue a sheet of aluminum foil to a sheet of glass and see how well that works.

Another bad solder joint on one of the end-stop switches. This is just ridiculous, and this time both contacts came off. It's not that hard to create a solder joint, I am very annoyed, I just was to get this done but everything keeps popping out of nowhere to stop me.

Finally got my printer in today. Was looking over things and noticed the wiring is odd for the steppers. There are 4 pin connectors and 6 pin connectors. The 4 pins are wired black green blue red. However the 6 pins are wired red green blue black. Which is correct? How can I fix it? Thanx.

Hope this helps a bit and good luck! (I'll let you know whether my own advice helps me at all )

My printer is due to come in tommorrow (after nearly a month and a bunch of lies). Anyway, I have read mixed reviews on the power supply that comes with this thing. Would it be better/safer to use the PSU that comes with it or an old ATX computer power supply (the one I am planning is rated at 19A on the 12v rail)?
