Well here goes... Aluminium frame router design

[CharlieRam]

So I had some issues with my AXBB charge pump output but that has now been resolved thanks to some helpful people on here .
This means that I have finally been able to make some movement on my machine however I'm not entirely happy with it.
What kind of rapid speeds would you expect on nema 23 and 70v driver/psu?
I may have to go for twin motors on the X axis or a higher power nema 34 as that seems to bind if I go above 12000 units per minute(I am running at 10000 to be safe) whereas y axis goes upto 17000 units before binding(running at 14000). The z axis is only around 8000 but I assume that's because of the ballscrew pitch.
Anyway, it's looking promising but there may be room for improvement.

The y axis is smooth one way but seems to have a judder when rapid in the opposite direction...any ideas?

The X axis sounds gratey in both directions ! I'm thinking it may be sounding worse because it runs on the steel box section and that may be amplifying the sound?
