    Well bit of an update. I sent the pcd back to planet and they emailed me back the day they received it saying there was a faulty bit of soldering on rhe board which they have rectified and tested. It is now back with me and I have re fitted it. This all took 3 days fir play to them foe sorting it quickly. Anyway I have been stripping the old control box to now house the stuff for the spindle motor

    - - - Updated - - -

    Here is the old box, I stripped it and sprayed it the same as the new control box as I want to mount the 2 together.


    Now I mounted the power supply thing and bolted it now, I spaced it about 5mm up off the deck to help air flow, not sure if it is needed but though as there are vents on the underside it would make sense.

    Now I have to find a place to fit the small pcb which has the speed control dial plugged into it


    Is it ok to mount this box directly ontop of my new box so it is nice and neat? I think the power will go from one box to another so it would be much neater if the cables were kept internal hence linking the boxes?

    Wow, that's a lot of work for a 3020.....you'll probably outgrow it once you play with it a bit......you didn't actually say what you are going to make with it.

    BTW....as you are masochistically inclined and want to "improve" everything on the machine, if you have problems with the stepper drivers or want to go better, go onto the MASSMINDS.ORG website.....James Newton et al.

    They have stepper driver kits and break out boards (DIY assembly etc) that are quoted to be a huge improvement on the Chinese stuff......specifically anything related to the TB6600 crap....they produce the kits using the TBH6064AH chip for better power output and reliability etc.

    If you Google MASSMINDS.ORG there is a video of the testing of the improved kit form as well as a list of the kits and pricing to date.

    Good Day Sir,
    I have a CNC same as yours and I too have been trying to get the CNC to work proper so I am liking this thread. I am wondering if you would like to sell one of your washers to take the play out of my Z.

    Right chaps I need some help. I have Wired the spindle control board up to my planet cnc enclosure box as instructed by Planet themselves. However I am having difficulty in getting advice on how to get power to the spindle power pack.

    Here is what I have done so far:

    I have removed the potentiometer, capped off one wire and wired the 0-5v and gnd to the pin6 and gnd on the planet board. I have soldered the wires and heat shrunk them

    I just dont know how to supply power from the enclosure box to the large silver power pack which is mounted on top for the spindle.

    It has these connections on it:
