We have a relatively new ShopSabre 23 with WinCNC in the school robotics shop. Coming from Haas/Doosan/Deckel, I programmed a bore operation in Fusion CAM using Compensation in the Control. The posted code came up with G41 O0.1875, which at first glance I took to mean that the cutter would be offset from the programmed path by 0.1875, which was the cutter radius. No so. The cut ran with no offset - the tool centerline followed to path, and we ended up with a hole diameter larger than desired by the amount of the cutter diameter.

Can WinCNC handle Comp in the Control in the "normal" way? If so. what's the trick? The WinCNC manual has these, which don't seem to explain the problem.
