From 1451b7eacf74c45a29e9ee41ba83c6f659df36a0 Mon Sep 17 00:00:00 2001 From: Roxy-3D Date: Thu, 6 Apr 2017 18:46:47 -0500 Subject: [PATCH] UBL's Grid Based Leveling code Pretty much... The code is in place. Still more work to do. But it has a lot of hooks and variables in other code, so commit and merge before I pick up a million 'Conflicts'. --- Marlin/G26_Mesh_Validation_Tool.cpp | 32 ++-- Marlin/Marlin.h | 9 ++ Marlin/Marlin_main.cpp | 2 - Marlin/_Bootscreen.h | 110 ++++++++++++++ Marlin/least_squares_fit.cpp | 134 +++++++++++++++++ Marlin/ubl.cpp | 19 +-- Marlin/ubl_G29.cpp | 221 ++++++++++++++++++++++++++-- Marlin/ubl_motion.cpp | 41 +++--- 8 files changed, 501 insertions(+), 67 deletions(-) create mode 100644 Marlin/_Bootscreen.h create mode 100644 Marlin/least_squares_fit.cpp diff --git a/Marlin/G26_Mesh_Validation_Tool.cpp b/Marlin/G26_Mesh_Validation_Tool.cpp index 12042a5de7..0bf62432a1 100644 --- a/Marlin/G26_Mesh_Validation_Tool.cpp +++ b/Marlin/G26_Mesh_Validation_Tool.cpp @@ -219,8 +219,8 @@ move_to(destination[X_AXIS], destination[Y_AXIS], destination[Z_AXIS], 0.0); move_to(destination[X_AXIS], destination[Y_AXIS], destination[Z_AXIS], ooze_amount); - ubl.has_control_of_lcd_panel++; - //debug_current_and_destination((char*)"Starting G26 Mesh Validation Pattern."); + ubl.has_control_of_lcd_panel = true; + //debug_current_and_destination(PSTR("Starting G26 Mesh Validation Pattern.")); /** * Declare and generate a sin() & cos() table to be used during the circle drawing.
