    That 4th axis would be very limited in what it can do. Not enough travel in the Z axis to turn anything of decent size. Also not much X axis left to turn anything of length.

    Apart from that machine looks ok and probably will be typical Chinese build. I got a similar machine with 4th axis and it works OK - not great but it works and priced better than I can buy the parts to make one. The 4th axis I got was smaller and had a tailstock.

    I got a pirated version of Mach3 with the machine. I have a legit copy so used that and the file of instructions they gave was next to useless. Be prepared to problem solve and you will get it going and it will be a good start to CNC projects. Price is the incentive for buying this machine. If you want a no problem turn key solution then look elsewhere.

    Hi White Cedar,

    I can't comment on the 4th axis, but I got a 3-axis machine from the same seller, I'm very happy with it, for a low cost machine I've found it to be very good.

    I've doing some upgrades, fitting a bigger spindle motor ( 800W water cooled) and I've got some 100W Yaskawa AC servos to replace the steppers.

    If you opt to run EMC2 I can give you a copy of the configuration files we ended up with.

    All in all a nice machine, it has it's limitations, but for the money I think it's a ripper.

    Regards
    Ray

    Default mini cnc

    I'm looking to make jigsaw puzzles and small toys. 200w seems to be quite small, most hand routers are 700w at least? So I'm guessing this will overheat quite fast if used continuously. I'd be cutting plywood sheet of 8mm most of the time.

    If I get the 4 axis and upgrade the spindle, how many hours a day will this run? 0.5mm consistent accuracy will do for me.

    Thanks

    0.5mm accuracy is not acceptable. 0.01 should be considered an absolute minimum for accuracy but try for 0.001. It is unlikely that you will obtain quite this degree of accuracy because of various mechanical limitations which tend to be cumulative.

    Yes, I agree with you that 200 watts is quite small for a CNC router unless you are only cutting out PC boards. I would go with the the 800 at a minimum and bigger if you can afford it. If you are buying a spindle then the noise factor alone will more than compensate you for the extra cost.
