During a 7 a.m. dry run with the laparoscopic trainer, our robot froze and flashed: “Target not within 0.3 mm — try again,” like a stern scrub nurse with a laser pointer. I’ll take the attitude if it means cleaner margins and safer patients; anyone else getting heckled by their safety interlocks?
Been there — a quick fiducial re-scan on the trainer before you start usually quiets it; I’ve caught a 0.4 mm shift just from the cart settling overnight. If it still nags, make sure the table’s leveled and the optics aren’t fogging; mine’s a coffee snob until it warms up, @OP. Do you see the error drop after a re-scan?
Try locking the scope’s exposure and autofocus before the dry run — tiny lighting flicker can make the tracker jitter and trigger the “0.3 mm” nag even when the arm’s rock solid. @j_gray21’s drift point is solid; if you freeze white balance too, does the sass calm down?
