Then do a G28 Z0 to move Z to the actual position of Z 0. @AnHardt I can move z up 50mm, then m119 (all open), and then down 10mm. #define Z_MIN_POS 0. It’s safer to leave Z as 0 here are calibrate this yourself later. Have a question about this project? to your account. Home is done ok, it is after it I can't move Z anymore down. My problem is with G38. Any hint? my variable is or'ed with abort_current_block and reset on M119 call. 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). Have a question about this project? Attached is my configuration.h all of my changes are bounded by #ifdef ChuckMod. Home is often done approaching bed, endstop are adjusted to be 'hit at pos 0', can't be lower that bed. Liked By View All Measure Z heights in a grid, enable leveling compensation. Place a piece of paper between the hotend and the print bed. Delta homes far from bed and can move far from endstops. 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). 3 3 0 0 0 0 0. 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. If those adjustments are big enough, after homing all hardware endstops are free. We’ll occasionally send you account related emails. In Marlin 1.x, this was done with X, Y and Z_PROBE_OFFSET_FROM_EXTRUDER. 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. You could experiment with the same idea to see if it fixes the issue for you. privacy statement. @thinkyhead is already in that area. Using the Creality BLTouch Kit bracket, mine is { -43, -9, 0 }. X, Y axis move fine (to right and back when adding +10 on the axis). #define Z_CLEARANCE_DEPLOY_PROBE 3 // Z Clearance for Deploy/Stow #define Z_CLEARANCE_BETWEEN_PROBES 3 // Z Clearance between probe points. Or am I doing something wrong? Units may be set to inches by G20. 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. Do you home with the probe? Trying G1 Z0 will show the Z probe endstop is hit and Z won't go any lower. The text was updated successfully, but these errors were encountered: @AnHardt the issue is not during home. calibration AUTO_BED_LEVELING_UBL G29 - Bed Leveling (Unified) ... Save current position and move to filament change position. Then go to Menu>Prepare>Move Axis>Z-axis>0.1 mm and start to move your hotend down.

Z offset = -2 + 0.6, meaning -1.4mm EDIT: Re-checked and everything looks ok in this regard. The current position is adjusted to align to the new home offset values. Here set the software endstop limits. Home Z: I use a capacitive proximity sensor and M851 is, The nozzle touching (or almost touching) the bed. This means you can no longer use G92 to move below the bed, for example. The value for X and Y can be quite coarse. @ejtagle I think I've found my issue cause. In CNC G-code G53 is a modifier. For now I guess I have to make sure nothing breaks... @Blue-Marlin will you care to submit a patch for this bug ? 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. By clicking “Sign up for GitHub”, you agree to our terms of service and 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. ... move Z-axis down by steps of 0.1 until it touches the paper. Z has to be accurate and has to be adjusted quite accurately. It’s safer to leave Z as 0 here are calibrate this yourself later. By clicking “Sign up for GitHub”, you agree to our terms of service and Interrupts are disabled and live_state will never be updated again. Is my understanding of Z_MIN_POS wrong? Homing feed rate. What must be done is to clear live_state at home end if and only if endstops are not "continuosly" tested. This means you can no longer use G92 to move below the bed, for example. 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. So I set both to 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. If you move from 0,0 to 2,1 the feedrate for X will be two times higher than the feedrate for Y. I'm not sure what you're trying to achieve, but changing the firmware probably isn't the right option. HI Everyone, Im setting up a new printer with Marlin 2.0.x on a Azteeg X5 GT from Panucatt and 32bit Im having a problem with Z homing to max endstop. @AnHardt I think I don't understand (it's not the first time I misunderstand you, please be patient). Still goes down to the same value as M851. Specs: SKR1.3, TMC2130 Sensorless Homing, Marlin 2.0.5.3, Ender 3. Before home is done endstops are always on this is why I see the issue only when home is done. marlin allow negative z, MARLIN FINANCIAL IS NOT LICENSED. Successfully merging a pull request may close this issue. 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. Notes. Does it make a difference if you make the test before or after G29? On cartesian I think this is not possible. Is my understanding of Z_MIN_POS wrong ? Marlin 2.0 introduces an option to maintain a separate default feedrate for G0. Don't know what is "DELTA style" since mine is cartesian and I never worked with delta printers. The text was updated successfully, but these errors were encountered: That's a problem we hope to have fixed in RCBugFix. 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. Set Gap Between Nozzle And Bed Using G-Code, EEPROM & Marlin Firmware Now my Z doesn't go below 0 even if i have a negative z offset set by M851. #define Z_MAX_POS 190. Thing Apps Enabled. Already on GitHub? Sign up for a free GitHub account to open an issue and contact its maintainers and the community. 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. Already on GitHub? I'm fairly new to the 3d printing world. one question not related in endstop.cpp: @ejtagle another question: But when I home the axis, they move to the right/front insted of left/back. G53 applies native workspace to the current move. 0,0 is on left bottom of the Buildplate, as usual. Tried to implement latest Marlin on my reprappro with ramps 1.4. After home: Also set_directions is called this confirm move is queued, I'm wondering, even if this is not my situation since I have DUAL_Z, if code below. This effectively shifts the coordinate space in the negative direction. * Useful to retract or move the Z probe out of the way. 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 Ender 5 Pro With BLTouch Marlin bugfix-2.0.x config - ender-5-pro.patch Likely the error is about here (https://github.com/MarlinFirmware/Marlin/pull/3829/files#diff-1cb08de130a6ece2d1b5b9c37bcfef48R1295). It is the total number of axis (3) plus the number of extruders (1). It seems that it bypass endstops when ENDSTOP_NOISE_FILTER is disabled and Endstop on interrupts are enabled. (MarlinFirmware:RCBugFix, last update 15/05/2016). In Marlin 1.x, this was done with X, Y, and Z_PROBE_OFFSET_FROM_EXTRUDER. 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. Isn't that the min value for Z ? On SCARA machines G0 does a fast non-linear move. This company is NOT a licensed Title Loan lender as required under Chapter 516.02(04), Florida Statutes through the State of Florida Department of Financial Regulation – The "Consumer Finance" license they do have, CF9901149, DOES NOT allow for Title Loan lending as defined in Florida Statute 538.03(1)(i). @thinkyhead I will assign this one to you then. With Marlin 1.0, the Z-axis works great (and has been for three years). since aligned motor will move in opposite home direction, when just one endstop is released, generated interrupt will detect such direction and will not set hit_state again, after homing all hardware endstops are free. Be sure that adjustment is always bigger than home bump mm for that axis. You signed in with another tab or window. Successfully merging a pull request may close this issue. It precedes a movement command (or other modifiers) on the same line. 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. Super weird thing: I loaded new firmware to get this issue but going back with PR it persists. See G54-G59.3 for workspace coordinate system. So thats good. I'm proceeding to try to understand why planner skip it, Of course M502 and M500 after every time I update firmware. 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. 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. Add DELTA style home adjustments in every case. Edit: hit_on_purpose is ok and it works. That's how I have my printer set up, at least. This is a requirement for proper working software endstops anyway. In earlier versions of Marlin G92 doesn't update the software endstops, so it was unsupported to set coordinates outside these boundaries. Interrupts promptly may reset hit_state but live_state is set because of at least one micro is pressed. In Marlin 2.x, they’re now combined in NOZZLE_TO_PROBE_OFFSET. Coordinates are given in millimeters by default. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. Since I have #define Z_MIN_POS 0, why is the head moving below 0 ? with a single search and very easily. Please can anyone help me. Thing Details Thing Files Apps Comments Makes Collections Remixes ... bug Marlin monoprice monoprice_ultimate Wanhao Wanhao_D6. Movement settings Define the number of axis. Sign in I have a stationary Z Probe, but in Marlin it says Inductive probes need space to keep from triggering early. */ The offset in X,Y, and Z are the values defined in the firmware (In Marlin Configuration.h). I see. Z moves both directions (ok never goes below 0 but after a rise I can lower) Sign in Using the Creality BLTouch Kit bracket, mine is { -43, -9, 0 }. privacy statement. ... 1.0.0-beta encoder I2C_POSITION_ENCODERS M860-M869 - I2C Position Encoders. https://github.com/MarlinFirmware/Marlin/pull/3829/files#diff-1cb08de130a6ece2d1b5b9c37bcfef48R1295, Fix bad movement in gcode_T when switching extruders. note the Z value (i.e 0.7mm) and subtract it from the initial value (2mm-0.7mm). I think that hit_state and live_state should be reset after validate_homing_move and not inside. 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. In Marlin 1.1.0 and up, the physical boundaries are maintained. Endstops.enable_globally(true); Marlin also accepts G53 on a line by itself as the command to return to the native workspace. Well, let’s start configuring our Marlin firmware to support BLTouch / 3DTouch sensors. Move to where we think Z height 0 is: G1 F60 Z0; Disable software end stops - Be careful! In my Configuration.h i have #define Z_MIN_POS 0. Everything is ok but it doesn't move down..never.. We’ll occasionally send you account related emails. Isn't that the min value for Z ? Description. 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. # 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. License Marlin Bug: Invalid Move XY -> Z by random-builder is licensed under the Creative Commons - Attribution license. In Marlin 2.x, they’re now combined in NOZZLE_TO_PROBE_OFFSET. To manually adjust the z-offset is to first auto-home your gMax. Use M206 to apply a persistent offset to the native home position and coordinate space. Isn't that the min value for Z? 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.) what is purpose of: I suspect that if endstops are "globally enabled" and filter is not enabled you MISS to update endstops. # define MBL_Z_STEP 0.025 // Step size while manually probing Z axis. Then you can do a M211 S0 to remove the safety measure for Z. To set the Z axis home offset on the 3d printer, you will use g-code commands including M206 for the home offset, M500 and M501 for the Marlin Firmware EEPROM feature, and G1 for controlled move to Z axis zero position. @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). See examples below. The patch i meant only corrected to software endstops for G92. I can imagine... Let me know if you need some help testing (when you have smth to test :D ) ... Since I have #define Z_MIN_POS 0, why is the head moving below 0 ? #define NUM_AXIS 4. M503 to Read the current values. Instructions are in the comments. Instructions are in the comments.

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. baricuda BARICUDA M126 - Baricuda 1 Open. No abort so endstops are not cause. Endstops.enable(false) Z moves both directions (ok never goes below 0 but after a rise I can lower) The Z_MIN_POS is -3 so the nozzle can move below Z0. 0.6 mm (0.6 mm is example, note your actual) Use this formula to determine your Z offset needed: e.g. Replaced Z min … What happens in my dual Z dual endstop (but I think this may be a problem for everyone): to your account, Before home: sequence example: I have an FLSun 3D Cube, running off an MKS GEN V.1.4 main board. I am using Marlin 1.1.0-RC7. Configure BLTouch / 3DTouch in Marlin. euclidian distance between points divided by time for move equals feedrate). Since I’m homing to Z-max when G28 is executed by marlin it will home Z first (moving to the endstop, and setting Z to Z_MAX_POS (0 in my case). What ive found so far: Physical endstop is triggered in the max when moving bed up to endstop, this is … Deltas do have home adjustments , not only for 1 axis of a pair, but 3 adjustments for all 3 of their axes. Simply make this change to the clamp_to_software_endstops function in Marlin_main.cpp: yes, that works. Please open a new issue for related bugs. My idea is to remove hit_on_purpose call from the position it is now and move it after dual alignment and clear also live_state (when interrupt are enabled and endstop are not always tested). Is my understanding of Z_MIN_POS wrong ? Now use the pronterface software to move Z lower until it grabs your test piece of paper. Adding the probe-z-offset is no big thing - but finding the right conditions for that to not break something else. In earlier versions of Marlin G92 doesn’t update the software endstops, so it was unsupported to set coordinates outside these boundaries. Notes. You signed in with another tab or window. Skip to # 5 if you're familar with Configuration.h in Marlin. Open the valve for Baricuda 1. Been using marlin 1.1 but wanted newest auto leveling and other bells and whistles. This issue has been automatically locked since there has not been any recent activity after it was closed. This is the moving speed of the axis when homing in [mm/min]. In Marlin 1.1.0 and up, the physical boundaries are maintained. If so - mesh, grid or 3-point?
