Hi,

I've got a 3020T 3-axis cnc primarily for pcb routing. Even with autolevelling, am getting some depth variation, so wondered if it's possible to get a floating head that would fit on this type of router?

I found this, which would seem perfect, but is obviously made for a specific machine, so will probably not fit:

Maybe this is impossible, but thought I'd ask.
