Hey mac

I only ran the test @ F2500.

I'm beginning to believe we were conned into buying this machine.
The technician/broker knew what I wanted to cut and said the machine would do it.
And when the truth came out he said we were pushing it beyond its limits.
I still say the we are not exceeding the limits and the machine should be able to do it. It can't even give a good finish @500mm/min

Anyone want a Super Minimill 2 $60 000 Australian. You may want to take it slow though.

So the MiniMill has a higher Resolution,per/rev so a smoother cutting machine, not as fast in rapids, but does a better job over all

The machine Resolution (low Encoder Count Per Rev) & control is where your problem is for high speed machining
