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

Well I have redone the soldering, and im pretty happy with it. Its still balled up a little but the prongs stick out through the board a fair bit so didnt really have a choice as I wanted the whole of the prong covered in solder, they are very round and meet the metal contact on the board pretty much perfectly, plent of solder also flowed into the connection to begin with :-)

singed the board coating a little but the solder had made a solid connection and like I say plent of solder has flowed into the conection

Yep looks much better, you can see now how they resemble the other original joints more, nice job.

also popped to my best mates workshop, he has a few little toys ;-)

:) Mates with benefits a , your plan for the control box and the earthing looks to be ok.

thanks very much lee, still a bit iffy but the main thing is I now know the theory behind it.

Yeah my mate does a lot of contracting to a few aerospace firms and has helped me out a fair bit with advice, nearly pissed himself when I showed him my 4 axis machine lol

Work has been crazy busy at the moment so only been able to do a little bit on the build. I have started to create an enclosure for the machine, this will consist of a sealed unit with 2 led strip light running at the top of the enclosure front to back each side. One side of the enclosure will be perspex and and front will be a hinged perspex door. There will be an extraction system installed on the side opposite the perspex. Its a very make-shift idea but it will serve a purpose I think and help keep the area as clean as possible.

I have replaced all the wood on the workbench from cheap thin mdf to 12mm thick ply wood for stability, weight and strength.



Now I have added a few coats of paint to the inside of the enclosure to aid lighting

And here is the side perspex screen installed

One other issue I have is that I now have a additional power supply/controller for my 600w spindle which wont fit within my planet control box. I have decided to fabricate another box lid which will fit and attach to the top of the existing planet box. Here is the grp mould I have made so far to achieve this


Nothing really that interesting and still haven't registered the license correctly since changing from the crap control box to the new one so hopefully I will be able to sort this at the weekend and make some progress on finishing the wiring. All in all enjoying the small amounts of time I spend on this so far which is great. More to come :-)

Have you had it cutting yet?

[ravihotwok]

After you all explained what a star was in the box it was obvious where it was when I opened it up. I have drilled a small hole near the motor connections and linked a bolt to the star so I can attached the earthed wires from the motor cable screens to it
