See examples below. Is my understanding of Z_MIN_POS wrong? Then do a G28 Z0 to move Z to the actual position of Z 0. #define Z_CLEARANCE_DEPLOY_PROBE 3 // Z Clearance for Deploy/Stow #define Z_CLEARANCE_BETWEEN_PROBES 3 // Z Clearance between probe points. Specs: SKR1.3, TMC2130 Sensorless Homing, Marlin 2.0.5.3, Ender 3. Axes do home and once both endstops are detected firmware calls validate_homing_move and everything is ok but after that it aligns Z and one of the axis may release the endstop. I can imagine... Let me know if you need some help testing (when you have smth to test :D ) ... Or if you wish, you can use our component search engine Markets.sx, where you can compare prices in different Marketplaces (Amazon, Aliexpress, Banggood, etc.) So homing-validation on Delta will have to be ensured to happen only at the points where endstops are known to be triggered. euclidian distance between points divided by time for move equals feedrate). In Marlin 2.x, they’re now combined in NOZZLE_TO_PROBE_OFFSET. Z moves both directions (ok never goes below 0 but after a rise I can lower) In my Configuration.h i have #define Z_MIN_POS 0. Edit: hit_on_purpose is ok and it works. Please open a new issue for related bugs. What must be done is to clear live_state at home end if and only if endstops are not "continuosly" tested. $\begingroup$ No, the feedrate for the individual axes is calculated so that the total feedrate is 9000mm/s (e.g. @ejtagle I think I've found my issue cause. calibration AUTO_BED_LEVELING_UBL G29 - Bed Leveling (Unified) ... Save current position and move to filament change position. It’s safer to leave Z as 0 here are calibrate this yourself later. Still goes down to the same value as M851. Is my understanding of Z_MIN_POS wrong ? When I run G29 (3 x 3 grid) all 9 points are probed and the LCD tells me that I am at z=0.79. Be sure that adjustment is always bigger than home bump mm for that axis. Simply make this change to the clamp_to_software_endstops function in Marlin_main.cpp: yes, that works. @thinkyhead I will assign this one to you then. Thing Details Thing Files Apps Comments Makes Collections Remixes ... bug Marlin monoprice monoprice_ultimate Wanhao Wanhao_D6. You could experiment with the same idea to see if it fixes the issue for you. Displayed quote increase and decrease correctly, movement is properly loaded into planner (Planner::_buffer_steps returns true and recalculate() is called) and M119 return all endstop open. Already on GitHub? Marlin also accepts G53 on a line by itself as the command to return to the native workspace. I'm pretty sure these adjustments to the software endstops are no longer required, so I'm removing them in #3829 (which is mainly to fix an issue where switching extruders could cause movement beyond the software endstops). Then go to Menu>Prepare>Move Axis>Z-axis>0.1 mm and start to move your hotend down. Z moves both directions (ok never goes below 0 but after a rise I can lower) Sign up for a free GitHub account to open an issue and contact its maintainers and the community. EDIT: Re-checked and everything looks ok in this regard. Since I have #define Z_MIN_POS 0, why is the head moving below 0 ? Don't know what is "DELTA style" since mine is cartesian and I never worked with delta printers. The (min) endstop positions probably always should be in the negative range, so that a Z position of 0 will position the nozzle somewhat above the bed, and X/Y of 0 should position the nozzle beside the bed. Have a question about this project? Replaced Z min … (MarlinFirmware:RCBugFix, last update 15/05/2016). In Marlin 1.x, this was done with X, Y, and Z_PROBE_OFFSET_FROM_EXTRUDER. Then it moves to home X, and it tries to move the Z-axis up to Z_HOMING_HEIGHT, which is set from Z_CLEARANCE_BETWEEN_PROBES if that is defined (which it was for me, and it was 5). Hmm ja. Isn't that the min value for Z ? I see. adjustment is to properly align Z dual stepper, value is mechanical dependent and will move only one stepper and may not be bigger than bump.
