Ive got a 3020 chinese machine, and touch wood ive had no problems with it so far. Well saying that the fuse keeps blowing on the spindle power supply when i turn on the controller. Ive done a lot of 2.5d work on it in mdf oak mahogany pine and the results all come out good.

Im going to start upgrading the bearing on the axis soon as there onyl 50p each from the local supplier. so that will be a massive £6 for higher spec bearings than what are in now:) happy days.

Dont be too disheartened with the problems on the machine. They are cheap and the parts are cheap but as a starter machine they are great to learn on.
