Simply make this change to the clamp_to_software_endstops function in Marlin_main.cpp: yes, that works. Z moves both directions (ok never goes below 0 but after a rise I can lower) Have a question about this project? If those adjustments are big enough, after homing all hardware endstops are free. 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. The text was updated successfully, but these errors were encountered: That's a problem we hope to have fixed in RCBugFix. To manually adjust the z-offset is to first auto-home your gMax. Specs: SKR1.3, TMC2130 Sensorless Homing, Marlin 2.0.5.3, Ender 3. It precedes a movement command (or other modifiers) on the same line. Successfully merging a pull request may close this issue. Well, let’s start configuring our Marlin firmware to support BLTouch / 3DTouch sensors. 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). 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. Prepare > Move axis > Move 0.1mm > Move Z; Slowly move the Z axis down until you have the correct first layer gap (paper or thin card method) Note the distance on the display e.g. calibration AUTO_BED_LEVELING_UBL G29 - Bed Leveling (Unified) ... Save current position and move to filament change position. @ejtagle I think I've found my issue cause. But when I home the axis, they move to the right/front insted of left/back. marlin allow negative z, MARLIN FINANCIAL IS NOT LICENSED. What must be done is to clear live_state at home end if and only if endstops are not "continuosly" tested. 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. You signed in with another tab or window. Already on GitHub? It is the total number of axis (3) plus the number of extruders (1). Then go to Menu>Prepare>Move Axis>Z-axis>0.1 mm and start to move your hotend down. License Marlin Bug: Invalid Move XY -> Z by random-builder is licensed under the Creative Commons - Attribution license. It’s safer to leave Z as 0 here are calibrate this yourself later. In Marlin 1.1.0 and up, the physical boundaries are maintained. ... move Z-axis down by steps of 0.1 until it touches the paper. 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. It seems that it bypass endstops when ENDSTOP_NOISE_FILTER is disabled and Endstop on interrupts are enabled. 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. @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). Be sure that adjustment is always bigger than home bump mm for that axis. Please open a new issue for related bugs. M503 to Read the current values. euclidian distance between points divided by time for move equals feedrate). https://github.com/MarlinFirmware/Marlin/pull/3829/files#diff-1cb08de130a6ece2d1b5b9c37bcfef48R1295, Fix bad movement in gcode_T when switching extruders. Have a question about this project? 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 2.x, they’re now combined in NOZZLE_TO_PROBE_OFFSET. #define Z_CLEARANCE_DEPLOY_PROBE 3 // Z Clearance for Deploy/Stow #define Z_CLEARANCE_BETWEEN_PROBES 3 // Z Clearance between probe points. Marlin also accepts G53 on a line by itself as the command to return to the native workspace. You signed in with another tab or window. Endstops.enable(false) In my Configuration.h i have #define Z_MIN_POS 0. Super weird thing: I loaded new firmware to get this issue but going back with PR it persists. In Marlin 1.x, this was done with X, Y and Z_PROBE_OFFSET_FROM_EXTRUDER. 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. What happens in my dual Z dual endstop (but I think this may be a problem for everyone): 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. On cartesian I think this is not possible. If not please check if you have defined, I have #define min_software_endstops true in Configuration.h. In Marlin 1.1.0 and up, the physical boundaries are maintained. (MarlinFirmware:RCBugFix, last update 15/05/2016). I'm fairly new to the 3d printing world. What ive found so far: Physical endstop is triggered in the max when moving bed up to endstop, this is … #define Z_MIN_POS 0. 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. baricuda BARICUDA M126 - Baricuda 1 Open. Is my understanding of Z_MIN_POS wrong? EDIT: Re-checked and everything looks ok in this regard. The value for X and Y can be quite coarse. 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. Delta homes far from bed and can move far from endstops. Interrupts are disabled and live_state will never be updated again. Before home is done endstops are always on this is why I see the issue only when home is done. Is my understanding of Z_MIN_POS wrong ? 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). By clicking “Sign up for GitHub”, you agree to our terms of service and This is a requirement for proper working software endstops anyway. privacy statement. Replaced Z min … So homing-validation on Delta will have to be ensured to happen only at the points where endstops are known to be triggered. Since I have #define Z_MIN_POS 0, why is the head moving below 0 ? The text was updated successfully, but these errors were encountered: @AnHardt the issue is not during home. 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). #define Z_MAX_POS 190. 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.) Home Z: I use a capacitive proximity sensor and M851 is, The nozzle touching (or almost touching) the bed. sequence example: The offset in X,Y, and Z are the values defined in the firmware (In Marlin Configuration.h). With Marlin 1.0, the Z-axis works great (and has been for three years). This means you can no longer use G92 to move below the bed, for example. G53 applies native workspace to the current move. 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. # define MBL_Z_STEP 0.025 // Step size while manually probing Z axis. See G54-G59.3 for workspace coordinate system. Open the valve for Baricuda 1. Everything is ok but it doesn't move down..never.. I am using Marlin 1.1.0-RC7. 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. The patch i meant only corrected to software endstops for G92. 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. That's how I have my printer set up, at least. Note: Slicers tend to override firmware feedrates! Then do a G28 Z0 to move Z to the actual position of Z 0. to your account. Trying G1 Z0 will show the Z probe endstop is hit and Z won't go any lower. In Marlin 2.x, they’re now combined in NOZZLE_TO_PROBE_OFFSET. This issue has been automatically locked since there has not been any recent activity after it was closed. Isn't that the min value for Z? If so - mesh, grid or 3-point? Using the Creality BLTouch Kit bracket, mine is { -43, -9, 0 }. Edit: hit_on_purpose is ok and it works. Is my understanding of Z_MIN_POS wrong ? This effectively shifts the coordinate space in the negative direction. Since I have #define Z_MIN_POS 0, why is the head moving below 0 ? My problem is with G38. So I set both to 3. This means you can no longer use G92 to move below the bed, for example. We’ll occasionally send you account related emails. Endstops.enable_globally(true); I'm proceeding to try to understand why planner skip it, Of course M502 and M500 after every time I update firmware. In Marlin 1.x, this was done with X, Y, and Z_PROBE_OFFSET_FROM_EXTRUDER. Isn't that the min value for Z ? 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. Now my Z doesn't go below 0 even if i have a negative z offset set by M851. Home is done ok, it is after it I can't move Z anymore down. No abort so endstops are not cause. Thing Details Thing Files Apps Comments Makes Collections Remixes ... bug Marlin monoprice monoprice_ultimate Wanhao Wanhao_D6. @thinkyhead is already in that area. */ Place a piece of paper between the hotend and the print bed. 0.6 mm (0.6 mm is example, note your actual) Use this formula to determine your Z offset needed: e.g. @AnHardt I can move z up 50mm, then m119 (all open), and then down 10mm. Hmm ja. I see. I can imagine... Let me know if you need some help testing (when you have smth to test :D ) ... one question not related in endstop.cpp: @ejtagle another question: Successfully merging a pull request may close this issue. I have an FLSun 3D Cube, running off an MKS GEN V.1.4 main board. Z has to be accurate and has to be adjusted quite accurately. The Z_MIN_POS is -3 so the nozzle can move below Z0. We’ll occasionally send you account related emails. Sign in You could experiment with the same idea to see if it fixes the issue for you. Now use the pronterface software to move Z lower until it grabs your test piece of paper.

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). In earlier versions of Marlin G92 doesn’t update the software endstops, so it was unsupported to set coordinates outside these boundaries. ... 1.0.0-beta encoder I2C_POSITION_ENCODERS M860-M869 - I2C Position Encoders. Notes. I think that hit_state and live_state should be reset after validate_homing_move and not inside. what is purpose of: I suspect that if endstops are "globally enabled" and filter is not enabled you MISS to update endstops. * Useful to retract or move the Z probe out of the way. 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). note the Z value (i.e 0.7mm) and subtract it from the initial value (2mm-0.7mm). Instructions are in the comments. Are there other settings than Z_PROBE_OFFSET_FROM_EXTRUDER that affect bed leveling? to your account, Before home: 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. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. Isn't that the min value for Z ? Does it make a difference if you make the test before or after G29? Instructions are in the comments. The current position is adjusted to align to the new home offset values. Likely the error is about here (https://github.com/MarlinFirmware/Marlin/pull/3829/files#diff-1cb08de130a6ece2d1b5b9c37bcfef48R1295). 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. move rise but doesn't lower. Z moves both directions (ok never goes below 0 but after a rise I can lower) 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 Then you can do a M211 S0 to remove the safety measure for Z. Add DELTA style home adjustments in every case. Deltas do have home adjustments , not only for 1 axis of a pair, but 3 adjustments for all 3 of their axes. Coordinates are given in millimeters by default. @AnHardt I think I don't understand (it's not the first time I misunderstand you, please be patient). In CNC G-code G53 is a modifier. This is the moving speed of the axis when homing in [mm/min]. This must also certainly be the case after we lower the nozzle below the "safe height," which is an optional part of G28 homing. @thinkyhead I will assign this one to you then. Thing Apps Enabled. Units may be set to inches by G20. See examples below. 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. Move to where we think Z height 0 is: G1 F60 Z0; Disable software end stops - Be careful! I have a stationary Z Probe, but in Marlin it says Inductive probes need space to keep from triggering early. #define NUM_AXIS 4. # 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. Here set the software endstop limits. my variable is or'ed with abort_current_block and reset on M119 call. Using the Creality BLTouch Kit bracket, mine is { -43, -9, 0 }. Configure BLTouch / 3DTouch in Marlin. with a single search and very easily. Home is often done approaching bed, endstop are adjusted to be 'hit at pos 0', can't be lower that bed. In earlier versions of Marlin G92 doesn't update the software endstops, so it was unsupported to set coordinates outside these boundaries. Do you home with the probe? 0,0 is on left bottom of the Buildplate, as usual. After home: Please can anyone help me. Don't know what is "DELTA style" since mine is cartesian and I never worked with delta printers. Description. 3 3 0 0 0 0 0. So thats good. Adding the probe-z-offset is no big thing - but finding the right conditions for that to not break something else. Liked By View All Use M206 to apply a persistent offset to the native home position and coordinate space. Marlin 2.0 introduces an option to maintain a separate default feedrate for G0.

Skip to # 5 if you're familar with Configuration.h in Marlin. Sign in Already on GitHub? I'm not sure what's its purpose. 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. 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. privacy statement. Or am I doing something wrong? Any hint? $\begingroup$ No, the feedrate for the individual axes is calculated so that the total feedrate is 9000mm/s (e.g. By clicking “Sign up for GitHub”, you agree to our terms of service and Notes. It’s safer to leave Z as 0 here are calibrate this yourself later. Movement settings Define the number of axis. Homing feed rate. 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. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. Z offset = -2 + 0.6, meaning -1.4mm Still goes down to the same value as M851. 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. Measure Z heights in a grid, enable leveling compensation. X, Y axis move fine (to right and back when adding +10 on the axis). Been using marlin 1.1 but wanted newest auto leveling and other bells and whistles. On SCARA machines G0 does a fast non-linear move. Tried to implement latest Marlin on my reprappro with ramps 1.4.
