    Hi

    Thanks for making the review video’s of the hobby CNC machines, they really give a better insight in the possibilities of the machines. Could you give a small word of advice? I would like to start to learn working with a CNC and my primary hobby projects would be milling aluminum for small interface parts, carving PCB’s and some wood work. A working area of 300x200x72mm is sufficient. Potential future upgrade with 4th axis, laser or 3D printing would be really interesting but is not a ‘must-have’ right now and might make the choice just overly complicated…
    I checked your videos of the Genmitsu 3020-PRO MAX and Genmitsu PROVerXL 4030. The PROVerXL 4030 might give more potential for bigger parts, but I really want to mill aluminum from time to time. Do you believe the 3020-PRO MAX would be the better choice or is there another device I should look at?

    Kind Regards

    Hello

    Would this CNC be useful if the main work is machining aluminum? I would like to achieve ±0.1 and max ±0.2mm tolerances and dimensions of the 3020 would be sufficient. Would the PROVerXL 4030 be a better choice or another CNC in one of your reviews for the same budget range as a PROVerXL 4030?

    Many thanks in advance. Your videos clear up a lot of things on the machines.

    Best Regards
    Jef

      You can mill aluminium with the 3020 but its not a stiff machine, so the depth of cut and feed rate have to be relatively low. It is quite a bit stiffer than a typical 3018 type machine though.
      The PRoverxl is considerably larger (takes up a lot of space) and the frame is stiffer, but it uses rollers. On balance I would say the Proverxl is the better option but consider the space required.
      The other option is to look for generic 3020 or 6040 Chinese cnc machines, these usually come with mach3 controllers, which I wouldn’t recommend if you want to do any pcb milling, as height mapping (essential for pcb milling) can be an issue.
      At this price range everything is a bit of a compromise.
