I didn't cut Pressure Point's arm and frame on it as they were made before I had the machine and so were water-jetted instead. Any new bits I attempt for it I'll do on the machine though, but from the aluminium I have tried on it, don't expect quick cuts.

Looking at the one you have linked, the machine itself looks virtually identical. The steppers are smaller and the spindle on it is 230w, I have the 600W air cooled spindle on mine. I don't know if that would hinder your ability to cut soft metals on it or how fast you could cut them but someone with more knowledge may be able to comment. The ER11 collect limits you to around a 6mm bit, but I don't think you'd want to be pushing a much bigger tool around with it anyway.
