Pb with CNC and PCB done with Kicad

Hello
I am trying to produce a gerber file for an electonic board to be process with a CNC.
On PCBnew on the module editor I have some “plain” circle where I will put the component.
When I import the component in PCB new, I have a thin circle around my “plain” circle (at the distance definein the design rules between to track).
If I put the mass around the componenet, the mass surface will not touch this circle. There will be a space between the mass and this thin circle.
When I use the gerber file with the CNC there will be some copper left at the place of the thin circle.
How do I remove this unwanted thin circle ?

Many Thanks

(Sorry my English is may be not so clear…)

I assume you’re talking about a plated through-hole (PTH) here?

That’s the ‘Pad Clearance’. You can define pad clearances in the footprint editor for single pads (priority 1) OR the whole footprint (priority 2) AND you can define pad clearances for all the pads of the board in pcbnew (priority 3).
If the pad clearances of higher priority are 0 (zero) then the next priority level takes over.

Sounds like your filled zone is set up for a different clearance as the pads…

There are:

  • pad clearance
  • track clearance
  • zone fill clearance

I guess to solve your issue you should do the following:
Hover with your mouse and no tool selected/active over the zone edge, hit [E]
In the dialog that comes up adjust the clearance to the same as you got for your pads.
Refill the zone by hitting [B]

Good news, simple respond
With “zone fill clearance adjustment” it should work.
I will test this evening and let you know.
Thanks
