From 16c83d203b9d5b0c797e2a0ee147ae3ecc3569a5 Mon Sep 17 00:00:00 2001 From: AnHardt Date: Wed, 6 Jul 2016 03:40:21 +0200 Subject: [PATCH] Make use of the good features of a sled probe for all probes. Move and extend axis_unhomed test to deploy/stow_z_probe(). Move and extend position store/restore to deploy/stow_z_probe(). Now all kinds of probes can use the 'E' parameter in G29/M48. Allen key probes can be used now for grid and 3-point levelling. Deploying the Allen Key probe uses big moves in z direction. Too dangerous for an unhomed z-axis. Throw a compile time error when we try to configure an Allen Key probe homing to z-min and having no other z-min-endstop. --- Marlin/Marlin_main.cpp | 146 +++++++++++++---------------------------- Marlin/SanityCheck.h | 11 ++-- 2 files changed, 49 insertions(+), 108 deletions(-) diff --git a/Marlin/Marlin_main.cpp b/Marlin/Marlin_main.cpp index 7fb99d6da..b9a88b512 100644 --- a/Marlin/Marlin_main.cpp +++ b/Marlin/Marlin_main.cpp @@ -1735,7 +1735,7 @@ static void clean_up_after_endstop_or_probe_move() { #endif //HAS_BED_PROBE -#if ENABLED(Z_PROBE_SLED) || ENABLED(Z_SAFE_HOMING) || HAS_PROBING_PROCEDURE +#if ENABLED(Z_PROBE_ALLEN_KEY) || ENABLED(Z_PROBE_SLED) || ENABLED(Z_SAFE_HOMING) || HAS_PROBING_PROCEDURE static bool axis_unhomed_error(const bool x, const bool y, const bool z) { const bool xx = x && !axis_homed[X_AXIS], yy = y && !axis_homed[Y_AXIS], @@ -1783,16 +1783,10 @@ static void clean_up_after_endstop_or_probe_move() { } #endif - if (axis_unhomed_error(true, false, false)) return; - - float oldXpos = current_position[X_AXIS]; // save x position - // Dock sled a bit closer to ensure proper capturing do_blocking_move_to_x(X_MAX_POS + SLED_DOCKING_OFFSET - ((stow) ? 1 : 0)); digitalWrite(SLED_PIN, !stow); // switch solenoid - do_blocking_move_to_x(oldXpos); // return to position before docking - } #endif // Z_PROBE_SLED @@ -1964,102 +1958,59 @@ static void clean_up_after_endstop_or_probe_move() { #endif #endif - static void deploy_z_probe() { + #define DEPLOY_PROBE() set_probe_deployed( true ) + #define STOW_PROBE() set_probe_deployed( false ) + + // returns false for ok and true for failure + static bool set_probe_deployed(bool deploy) { #if ENABLED(DEBUG_LEVELING_FEATURE) - if (DEBUGGING(LEVELING)) DEBUG_POS("deploy_z_probe", current_position); + if (DEBUGGING(LEVELING)) { + DEBUG_POS("set_probe_deployed", current_position); + SERIAL_ECHOPAIR("deploy: ", deploy); + } #endif - if (endstops.z_probe_enabled) return; + if (endstops.z_probe_enabled == deploy) return false; // Make room for probe do_probe_raise(_Z_RAISE_PROBE_DEPLOY_STOW); - #ifdef _TRIGGERED_WHEN_STOWED_TEST - // If endstop is already false, the Z probe is deployed - if (_TRIGGERED_WHEN_STOWED_TEST) { // closed after the probe specific actions. - // Would a goto be less ugly? - //while (!_TRIGGERED_WHEN_STOWED_TEST) { idle(); // would offer the opportunity - // for a triggered when stowed manual probe. - #endif - #if ENABLED(Z_PROBE_SLED) - - dock_sled(false); - - #elif HAS_Z_SERVO_ENDSTOP - - // Engage Z Servo endstop if enabled - DEPLOY_Z_SERVO(); - + if (axis_unhomed_error(true, false, false)) { stop(); return true; } #elif ENABLED(Z_PROBE_ALLEN_KEY) - - run_deploy_moves_script(); - - #else - - // Nothing to be done.
