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

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,

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.

ffs!

No problem clive, will take that board out tonight and do as you say to make sure as the last thing I want is parts burning out, will be doing it around 7pm tonight so will do one re solder and post a pic up to see if its satisfactory before I crack on with the rest mate, be handy if you can keep an eye out pal.
I appreciate everyone's input :-)

right im at work doing a bit of skiving watching homeland and messing with this control box, I have re soldered the plug connections as advised, pelase have a look and give me your thoughts, don't think I can do much better if I'm honest
before


And now after re soldering

[Clive S]

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?

[ravihotwok]

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.

Did a bit more on the machine this weekend, my new 600w spindle and pwr supply arrived as well


I have allso installed the limit switches, 2 on each x and y axis and one on the z axis
