  1. thats very helpful and exactly what I was aiming for as you have echoed what I watched in a tutorial, but remember this is my first time so even though the theory is there putting it into practice is another matter lol. Hopefully ive not cooked anything, just waiting on further instructions on the advanced addons for this box from planet then I should be able to fire the thing up.

  2. Managed to get a bit more done tonight. I have decided to install limit switches to help prevent damage and to aid homing. I have decided to put 2 each of the x and y axis and one on the z axis. I have soldered 2 small tails to the switches in NC configuration and crimped a small 2 pin plug for future maintenance/removal

    First job was to solder the pins to the board for the motor connections and other plugs which in not sure of lol
    Ravi I would re solder (re flow all the motor connections that look and are bad on that board) as they will give you trouble and it si possible that could blow the drives if there is a dry joint. The resistors look a lot better.

    All you need to do is put the iron back on them and when the solder starts to flow with the iron still on apply a bit more solder and the flux will do the rest. I know this may be controversial but full lead solder is a lot easier to use.

    Ravi They are better but some are not good. It does take practise I think you said you have leaded solder.

    You will have to power it up and see. Remember always apply the solder to the joint (its ok to wet the iron first with solder) It should run and not ball up. What is the wattage of your iron?

  11. i have balled it up deliberately, once I had allowed plenty to go into the terminal i then gently moved the iron in a circular motion to ensure the solder didnt interfere with the next one. Iron is 30watt matey

    Too much solder, you should be able to see the shape of the parts after they are soldered.
