so go print something !
:-)
let's see what you can do quality wise at 150mm's and 0.4 layer height - basically what I use for rough prints on my £200 delta.
Mind you I do use a 0.5mm nozzle.
So I'll accept 150 and 0.3 layer height on a 0.4 :-)

let's face it, ANY machine can do quality at low speeds and thin layers. Where it's at, is the larger layers and faster speeds.

And - obviously get the mumu working :-)

Give me a model and we can have a print off ! :-)
