This is simple thing to make. Just linear rails with spring pushing down for tension. The depth is controlled with the adjustable height plastic depth control.
Daft as it sounds you could just remove power from your Z axis stepper so there is no holding torque. Fit strong spring to pull down on Z axis then fit plastic collar to the tool to control depth.!! . . . .Instant depth control.

Thanks, yes, homemade may be the only way since I've a 57mm spindle - and there doesn't seem to be any floating heads for that diameter spindle. Not sure if just removing the power from the Z motor would be enough, the spindle is still attached to the thread.
Re: Floating Head for 3020
Hi
We have come across this before regarding PCB work, there was a post with a link to software to compensate, you secure your work and using a probe take readings to the face of the PCB or whatever in various positions(grid) the software uses this to plot Z axis offsets.

That's why you need a strong spring to pull down the Z axis. If strong spring can't pull it down then your Z axis is binding and needs looking at.!!
