Ball end G-code generator - eliptic curve #4

Closed KyrreKnive closed 7 months ago

KyrreKnive commented 8 months ago

Hi Maxim,

I am trying to generate a ball end, but my input seems to generate an unevan curve on the left side. STOCK D10 TOOL ROUND R0.2 L1.5

L4 DS0 DE8 CONV

L3.464 DS8 DE4 CONV ; 3.464 is the legth from center where the diameter = 4 L4 D4

Did you mean RECT tool instead of ROUND?

First workaround is to define the full sphere but use the cutter that can't cut into the deep part e.g. parting blade:

Second workaround is draw the picture on figma.com with your exact dimensions (1px = 0.01mm) and use From image button.

Thank's for the workarounds! Can you post the calculation (program lines) for the curve /elipse function (L3.464 DS8 DE4 CONV ) ?
