From f7567a0db954eabe4c6b8da3f73ce68693698646 Mon Sep 17 00:00:00 2001 From: Kevin O'Connor Date: Sat, 21 Oct 2023 15:45:47 -0400 Subject: [PATCH] Revert "toolhead: Use dict for step generation flush times. (#6303)" This reverts commit 6749985302fe002a9cb5672dab9badb11e4e3c36. A defect was found in the above commit (the input shaper code calls note_step_generateion_scan_time() for many steppers, so the input_shaper class can't be used as the index).
