marlin move z to 0

Instructions are in the comments. This means you can no longer use G92 to move below the bed, for example. On cartesian I think this is not possible. You signed in with another tab or window. Adding the probe-z-offset is no big thing - but finding the right conditions for that to not break something else. Likely the error is about here (https://github.com/MarlinFirmware/Marlin/pull/3829/files#diff-1cb08de130a6ece2d1b5b9c37bcfef48R1295). G53 applies native workspace to the current move. Successfully merging a pull request may close this issue. G1 Z-5 Recv: ok Send: M114 Recv: X:105.00 Y:10.00 Z:-3.60 E:0.00 Regardless what value I send for Z which is < -3.6 the head stops at -3.6, or whatever value I have set for M851. Is my understanding of Z_MIN_POS wrong? Hmm ja. When I run G28 the X & Y home on their respective endstops as before, and Z now moves to the middle of the bed and homes Z using the Z probe. By clicking “Sign up for GitHub”, you agree to our terms of service and Marlin 2.0 introduces an option to maintain a separate default feedrate for G0. Z moves both directions (ok never goes below 0 but after a rise I can lower) Home Z: I use a capacitive proximity sensor and M851 is, The nozzle touching (or almost touching) the bed. Delta homes far from bed and can move far from endstops. Place a piece of paper between the hotend and the print bed. In Marlin 2.x, they’re now combined in NOZZLE_TO_PROBE_OFFSET. G1 Z2.0 F3000 ; Move Z Axis up little to prevent scratching of Heat Bed G1 X0.1 Y20 Z0.3 F5000.0 ; Move to start position G1 X0.1 Y200.0 Z0.3 F1500.0 E15 ; Draw the first line This means you can no longer use G92 to move below the bed, for example. #define NUM_AXIS 4. Is my understanding of Z_MIN_POS wrong ? Skip to # 5 if you're familar with Configuration.h in Marlin. Attached is my configuration.h all of my changes are bounded by #ifdef ChuckMod. one question not related in endstop.cpp: @ejtagle another question: Isn't that the min value for Z ? Measure Z heights in a grid, enable leveling compensation. EDIT: Re-checked and everything looks ok in this regard. Do you home with the probe? Sign in See examples below. Then go to Menu>Prepare>Move Axis>Z-axis>0.1 mm and start to move your hotend down. Replaced Z min … Specs: SKR1.3, TMC2130 Sensorless Homing, Marlin 2.0.5.3, Ender 3. This must also certainly be the case after we lower the nozzle below the "safe height," which is an optional part of G28 homing. # define LCD_PROBE_Z_RANGE 4 // Z Range centered on Z_MIN_POS for LCD Z adjustment # define LEVEL_BED_CORNERS // Add an option to move between corners # endif /* * * Commands to execute at the end of G29 probing. It is the total number of axis (3) plus the number of extruders (1). This issue has been automatically locked since there has not been any recent activity after it was closed. Everything is ok but it doesn't move down..never.. What happens in my dual Z dual endstop (but I think this may be a problem for everyone): Since I have #define Z_MIN_POS 0, why is the head moving below 0 ? marlin allow negative z, MARLIN FINANCIAL IS NOT LICENSED. Are there other settings than Z_PROBE_OFFSET_FROM_EXTRUDER that affect bed leveling? $\begingroup$ No, the feedrate for the individual axes is calculated so that the total feedrate is 9000mm/s (e.g. Here set the software endstop limits. 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. my variable is or'ed with abort_current_block and reset on M119 call. https://github.com/MarlinFirmware/Marlin/pull/3829/files#diff-1cb08de130a6ece2d1b5b9c37bcfef48R1295, Fix bad movement in gcode_T when switching extruders. 1) Download install the Arduino IDE and get the latest version of Marlin or your printer MFG available version that has auto-leveling in the Configuration.h file.. 2) Un-zip the Marlin contents into any specially named folder. euclidian distance between points divided by time for move equals feedrate). to your account, Before home: Homing feed rate. The value for X and Y can be quite coarse. So homing-validation on Delta will have to be ensured to happen only at the points where endstops are known to be triggered. endstops are always enabled but you don't test them, I'll make a PR to solve my problem and I'll do what you will suggest me, so don't post any PR to fix them, @thinkyhead, @AnHardt and @ejtagle I finally discovered what is the real bug but I have some doubt about how to solve it. Units may be set to inches by G20. 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.) #define Z_MAX_POS 190. Now my Z doesn't go below 0 even if i have a negative z offset set by M851. If so - mesh, grid or 3-point? Isn't that the min value for Z? I checked if the probe activates at the same level by moving it up and down 10 times: it always comes on at exactly the same height. To manually adjust the z-offset is to first auto-home your gMax. 0.6 mm (0.6 mm is example, note your actual) Use this formula to determine your Z offset needed: e.g. It's like z movement is multiplied by 10 and I'm not sure what I have to change in marlin code to fix it. The Z_MIN_POS is -3 so the nozzle can move below Z0. Deltas do have home adjustments , not only for 1 axis of a pair, but 3 adjustments for all 3 of their axes. Weâll occasionally send you account related emails. baricuda BARICUDA M126 - Baricuda 1 Open. If not please check if you have defined, I have #define min_software_endstops true in Configuration.h. Endstops.enable_globally(true); In Marlin 1.1.0 and up, the physical boundaries are maintained. My problem is with G38. Add DELTA style home adjustments in every case. Z offset = -2 + 0.6, meaning -1.4mm Note: Slicers tend to override firmware feedrates! Use M206 to apply a persistent offset to the native home position and coordinate space. Then you can do a M211 S0 to remove the safety measure for Z. 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. move rise but doesn't lower. Or am I doing something wrong? Interrupts are disabled and live_state will never be updated again. Configure BLTouch / 3DTouch in Marlin. M119 will report real input status so when I raise with Z it correctly say "open" but live_state tells another story and will block all "towards home" movements. note the Z value (i.e 0.7mm) and subtract it from the initial value (2mm-0.7mm). @AnHardt I think I don't understand (it's not the first time I misunderstand you, please be patient). See G54-G59.3 for workspace coordinate system. Tried to implement latest Marlin on my reprappro with ramps 1.4. Have a question about this project? Now I'm checking inside stepper isr to see why it stop... Edit: Weird thing is that before home it moves... added a debug test inside stepper isr just after endstops.update() call. Does it make a difference if you make the test before or after G29? Endstops.enable(false) @thinkyhead is already in that area. I'm in process of editing marlin for my 3d printer (ender 3 with skr 1.4) and I'm almost finished but I'm running into a problem that my Z-axis when selected to move 10mm moves by 10cm, when by 1mm it moves by 1cm. Super weird thing: I loaded new firmware to get this issue but going back with PR it persists. You could experiment with the same idea to see if it fixes the issue for you. Already on GitHub? #define Z_MIN_POS 0. Z moves both directions (ok never goes below 0 but after a rise I can lower) 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). I see. Then do a G28 Z0 to move Z to the actual position of Z 0. Still goes down to the same value as M851. Set Gap Between Nozzle And Bed Using G-Code, EEPROM & Marlin Firmware 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). This is a requirement for proper working software endstops anyway. This effectively shifts the coordinate space in the negative direction. ... 1.0.0-beta encoder I2C_POSITION_ENCODERS M860-M869 - I2C Position Encoders. When the nozzle starts to get close to the print bed, start to move the piece of paper with your hand at the same time. It’s safer to leave Z as 0 here are calibrate this yourself later. It precedes a movement command (or other modifiers) on the same line. Notes. The offset in X,Y, and Z are the values defined in the firmware (In Marlin Configuration.h). Successfully merging a pull request may close this issue. In CNC G-code G53 is a modifier. Been using marlin 1.1 but wanted newest auto leveling and other bells and whistles. I'm proceeding to try to understand why planner skip it, Of course M502 and M500 after every time I update firmware. Z has to be accurate and has to be adjusted quite accurately. It seems that it bypass endstops when ENDSTOP_NOISE_FILTER is disabled and Endstop on interrupts are enabled. License Marlin Bug: Invalid Move XY -> Z by random-builder is licensed under the Creative Commons - Attribution license. M503 to Read the current values. Well, let’s start configuring our Marlin firmware to support BLTouch / 3DTouch sensors. Home is often done approaching bed, endstop are adjusted to be 'hit at pos 0', can't be lower that bed. Any hint? Be sure that adjustment is always bigger than home bump mm for that axis. You signed in with another tab or window. @MoonshineSG The software endstop for Z currently gets extended based on any negative probe offset and based on any negative home_offset (as set with M206). 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. Movement settings Define the number of axis. Using the Creality BLTouch Kit bracket, mine is { -43, -9, 0 }. In earlier versions of Marlin G92 doesn’t update the software endstops, so it was unsupported to set coordinates outside these boundaries. In Marlin 2.x, they’re now combined in NOZZLE_TO_PROBE_OFFSET. In Marlin 1.1.0 and up, the physical boundaries are maintained. This is the moving speed of the axis when homing in [mm/min]. By clicking “Sign up for GitHub”, you agree to our terms of service and calibration AUTO_BED_LEVELING_UBL G29 - Bed Leveling (Unified) ... Save current position and move to filament change position.

(MarlinFirmware:RCBugFix, last update 15/05/2016). Have a question about this project? Move to where we think Z height 0 is: G1 F60 Z0; Disable software end stops - Be careful! Marlin also accepts G53 on a line by itself as the command to return to the native workspace.
