Use a spot drill before the small drill to get the hole on center and true. "Real" CAM software usually lets you select spot drilling for each hole. Then it generates tool path for the spot drill operation before tool path for the regular drill.
I would love for FreeCAD to gain the features other CAD/CAM software has. I keep trying it out, but keep getting stuck with some key missing piece. I haven't made the commitment to get involved in development though. They came out with a new release fairly recently, so I believe it is under active development. -- Ralph ________________________________________ From: Nicklas SB Karlsson [n...@nksb.eu] Sent: Thursday, October 20, 2022 7:23 AM To: emc-users@lists.sourceforge.net Subject: [Emc-users] Freecad path workbench + drilling small hole CAUTION: This email originated from outside the Walla Walla University email system. There is some things missing in the Freecad path workbench of which some are rather simple to fix. Zig facing operation, rigid tapping, G95 feed per revolution or tooth is not possible and these are probably not to hard to fix. While reorder and get blank from machining of previous operation might be harder. Have been able to figure a little bit on the data model add a zig function but had to disable some kind of sorting function sometimes changing direction of cut, probably to get shortest path. Have registered to Freecad mailing lists and posted on at least one of them but they seems dead. Anybody else activing in Freecad? Just starting to machine my first parts milling seems to work rather well. Drilling small holes a few millimeters I am however a little bit uncertain it work well to start a hole with a normal length drill? Or start point tend to slip a little bit on the surface?
