Thread: Floating Head for 3020
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.
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.
The word Impossible doesn't exist on this Forum...Clive
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.
