You signed in with another tab or window. This means you can no longer use G92 to move below the bed, for example. I'm fairly new to the 3d printing world. Have a question about this project? Please can anyone help me. Interrupts promptly may reset hit_state but live_state is set because of at least one micro is pressed. Liked By View All You signed in with another tab or window. Note: Slicers tend to override firmware feedrates! Any hint? In earlier versions of Marlin G92 doesn't update the software endstops, so it was unsupported to set coordinates outside these boundaries. move rise but doesn't lower. #define NUM_AXIS 4. 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 note the Z value (i.e 0.7mm) and subtract it from the initial value (2mm-0.7mm). Ender 5 Pro With BLTouch Marlin bugfix-2.0.x config - ender-5-pro.patch 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. Does it make a difference if you make the test before or after G29? Configure BLTouch / 3DTouch in Marlin. After home: I'm not sure what's its purpose. #define Z_CLEARANCE_DEPLOY_PROBE 3 // Z Clearance for Deploy/Stow #define Z_CLEARANCE_BETWEEN_PROBES 3 // Z Clearance between probe points. 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. See examples below. 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. We’ll occasionally send you account related emails. 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). 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. Be sure that adjustment is always bigger than home bump mm for that axis. Units may be set to inches by G20. It’s safer to leave Z as 0 here are calibrate this yourself later. Instructions are in the comments. Tried to implement latest Marlin on my reprappro with ramps 1.4. Delta homes far from bed and can move far from endstops. In CNC G-code G53 is a modifier. # define MBL_Z_STEP 0.025 // Step size while manually probing Z axis. My problem is with G38. 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). If so - mesh, grid or 3-point? In my Configuration.h i have #define Z_MIN_POS 0. I'm proceeding to try to understand why planner skip it, Of course M502 and M500 after every time I update firmware. This means you can no longer use G92 to move below the bed, for example. Edit: hit_on_purpose is ok and it works. G53 applies native workspace to the current move. Then you can do a M211 S0 to remove the safety measure for Z. This effectively shifts the coordinate space in the negative direction. Already on GitHub? Deltas do have home adjustments , not only for 1 axis of a pair, but 3 adjustments for all 3 of their axes. # 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 seems that it bypass endstops when ENDSTOP_NOISE_FILTER is disabled and Endstop on interrupts are enabled. Move to where we think Z height 0 is: G1 F60 Z0; Disable software end stops - Be careful! Notes. It is the total number of axis (3) plus the number of extruders (1). 0,0 is on left bottom of the Buildplate, as usual. The Z_MIN_POS is -3 so the nozzle can move below Z0. If not please check if you have defined, I have #define min_software_endstops true in Configuration.h. This must also certainly be the case after we lower the nozzle below the "safe height," which is an optional part of G28 homing. What ive found so far: Physical endstop is triggered in the max when moving bed up to endstop, this is … I see. Using the Creality BLTouch Kit bracket, mine is { -43, -9, 0 }. On SCARA machines G0 does a fast non-linear move. Then do a G28 Z0 to move Z to the actual position of Z 0. That's how I have my printer set up, at least. In earlier versions of Marlin G92 doesn’t update the software endstops, so it was unsupported to set coordinates outside these boundaries. 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. The value for X and Y can be quite coarse. What must be done is to clear live_state at home end if and only if endstops are not "continuosly" tested. I am using Marlin 1.1.0-RC7. Isn't that the min value for Z? Sign up for a free GitHub account to open an issue and contact its maintainers and the community. This issue has been automatically locked since there has not been any recent activity after it was closed. Home is done ok, it is after it I can't move Z anymore down. Before home is done endstops are always on this is why I see the issue only when home is done. calibration AUTO_BED_LEVELING_UBL G29 - Bed Leveling (Unified) ... Save current position and move to filament change position. Attached is my configuration.h all of my changes are bounded by #ifdef ChuckMod. I have a stationary Z Probe, but in Marlin it says Inductive probes need space to keep from triggering early. 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. I can imagine... Let me know if you need some help testing (when you have smth to test :D ) ... Don't know what is "DELTA style" since mine is cartesian and I never worked with delta printers. The patch i meant only corrected to software endstops for G92. to your account, Before home: The current position is adjusted to align to the new home offset values. Replaced Z min … @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). 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. On cartesian I think this is not possible. * Useful to retract or move the Z probe out of the way. $\begingroup$ No, the feedrate for the individual axes is calculated so that the total feedrate is 9000mm/s (e.g. Set Gap Between Nozzle And Bed Using G-Code, EEPROM & Marlin Firmware This is a requirement for proper working software endstops anyway. If those adjustments are big enough, after homing all hardware endstops are free. Sign in Then go to Menu>Prepare>Move Axis>Z-axis>0.1 mm and start to move your hotend down. Is my understanding of Z_MIN_POS wrong ? In Marlin 2.x, they’re now combined in NOZZLE_TO_PROBE_OFFSET. 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. You could experiment with the same idea to see if it fixes the issue for you. EDIT: Re-checked and everything looks ok in this regard. Specs: SKR1.3, TMC2130 Sensorless Homing, Marlin 2.0.5.3, Ender 3. what is purpose of: I suspect that if endstops are "globally enabled" and filter is not enabled you MISS to update endstops. 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). 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. Successfully merging a pull request may close this issue. Use M206 to apply a persistent offset to the native home position and coordinate space. Z has to be accurate and has to be adjusted quite accurately. Isn't that the min value for Z ? Marlin 2.0 introduces an option to maintain a separate default feedrate for G0. with a single search and very easily. Movement settings Define the number of axis. Is my understanding of Z_MIN_POS wrong ? 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. Instructions are in the comments. 3 3 0 0 0 0 0. Please open a new issue for related bugs. The offset in X,Y, and Z are the values defined in the firmware (In Marlin Configuration.h). Add DELTA style home adjustments in every case. Endstops.enable(false) License Marlin Bug: Invalid Move XY -> Z by random-builder is licensed under the Creative Commons - Attribution license. Do you home with the probe? Notes. By clicking “Sign up for GitHub”, you agree to our terms of service and 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). (MarlinFirmware:RCBugFix, last update 15/05/2016). 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. Coordinates are given in millimeters by default. By clicking “Sign up for GitHub”, you agree to our terms of service and Open the valve for Baricuda 1. This is the moving speed of the axis when homing in [mm/min]. @thinkyhead is already in that area. 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. Have a question about this project? But when I home the axis, they move to the right/front insted of left/back. privacy statement. Home is often done approaching bed, endstop are adjusted to be 'hit at pos 0', can't be lower that bed. baricuda BARICUDA M126 - Baricuda 1 Open. X, Y axis move fine (to right and back when adding +10 on the axis). Interrupts are disabled and live_state will never be updated again. What happens in my dual Z dual endstop (but I think this may be a problem for everyone): ... move Z-axis down by steps of 0.1 until it touches the paper. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. Endstops.enable_globally(true); Home Z: I use a capacitive proximity sensor and M851 is, The nozzle touching (or almost touching) the bed. Simply make this change to the clamp_to_software_endstops function in Marlin_main.cpp: yes, that works. 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. 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. Successfully merging a pull request may close this issue. In Marlin 2.x, they’re now combined in NOZZLE_TO_PROBE_OFFSET. Everything is ok but it doesn't move down..never.. Is my understanding of Z_MIN_POS wrong? Thing Apps Enabled. Skip to # 5 if you're familar with Configuration.h in Marlin. Thing Details Thing Files Apps Comments Makes Collections Remixes ... bug Marlin monoprice monoprice_ultimate Wanhao Wanhao_D6. Using the Creality BLTouch Kit bracket, mine is { -43, -9, 0 }. To manually adjust the z-offset is to first auto-home your gMax. 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. 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. privacy statement. Marlin also accepts G53 on a line by itself as the command to return to the native workspace. 0.6 mm (0.6 mm is example, note your actual) Use this formula to determine your Z offset needed: e.g. Sign in Or am I doing something wrong? 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. Since I have #define Z_MIN_POS 0, why is the head moving below 0 ? Are there other settings than Z_PROBE_OFFSET_FROM_EXTRUDER that affect bed leveling? 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. ... 1.0.0-beta encoder I2C_POSITION_ENCODERS M860-M869 - I2C Position Encoders. Adding the probe-z-offset is no big thing - but finding the right conditions for that to not break something else. Hmm ja. It precedes a movement command (or other modifiers) on the same line. So I set both to 3. 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.) https://github.com/MarlinFirmware/Marlin/pull/3829/files#diff-1cb08de130a6ece2d1b5b9c37bcfef48R1295, Fix bad movement in gcode_T when switching extruders. Place a piece of paper between the hotend and the print bed. euclidian distance between points divided by time for move equals feedrate). No abort so endstops are not cause. Description. 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). 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. So thats good. In Marlin 1.1.0 and up, the physical boundaries are maintained. In Marlin 1.x, this was done with X, Y, and Z_PROBE_OFFSET_FROM_EXTRUDER. M503 to Read the current values. Since I have #define Z_MIN_POS 0, why is the head moving below 0 ? @thinkyhead I will assign this one to you then. marlin allow negative z, MARLIN FINANCIAL IS NOT LICENSED. See G54-G59.3 for workspace coordinate system. Now use the pronterface software to move Z lower until it grabs your test piece of paper. G1 X10.1 Y200.0 Z0.28 F1500.0 E15 ;Draw the first line G1 X10.4 Y200.0 Z0.28 F5000.0 ;Move to side a little G1 X10.4 Y20 Z0.28 F1500.0 E30 ;Draw the second line G92 E0 ;Reset Extruder G1 Z2.0 F3000 ;Move Z Axis up One last thing. Z offset = -2 + 0.6, meaning -1.4mm The text was updated successfully, but these errors were encountered: @AnHardt the issue is not during home. Z moves both directions (ok never goes below 0 but after a rise I can lower) I think that hit_state and live_state should be reset after validate_homing_move and not inside. In Marlin 1.1.0 and up, the physical boundaries are maintained. Well, let’s start configuring our Marlin firmware to support BLTouch / 3DTouch sensors. 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. Now my Z doesn't go below 0 even if i have a negative z offset set by M851. @AnHardt I think I don't understand (it's not the first time I misunderstand you, please be patient). #define Z_MIN_POS 0. Been using marlin 1.1 but wanted newest auto leveling and other bells and whistles. It’s safer to leave Z as 0 here are calibrate this yourself later. Measure Z heights in a grid, enable leveling compensation. 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. Homing feed rate. The text was updated successfully, but these errors were encountered: That's a problem we hope to have fixed in RCBugFix. one question not related in endstop.cpp: @ejtagle another question: Likely the error is about here (https://github.com/MarlinFirmware/Marlin/pull/3829/files#diff-1cb08de130a6ece2d1b5b9c37bcfef48R1295). #define Z_MAX_POS 190. Isn't that the min value for Z ? Z moves both directions (ok never goes below 0 but after a rise I can lower) 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. So homing-validation on Delta will have to be ensured to happen only at the points where endstops are known to be triggered. Trying G1 Z0 will show the Z probe endstop is hit and Z won't go any lower. Already on GitHub? For now I guess I have to make sure nothing breaks... @Blue-Marlin will you care to submit a patch for this bug ? sequence example: 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. Here set the software endstop limits. I have an FLSun 3D Cube, running off an MKS GEN V.1.4 main board. @ejtagle I think I've found my issue cause. to your account. my variable is or'ed with abort_current_block and reset on M119 call. */ Still goes down to the same value as M851. @AnHardt I can move z up 50mm, then m119 (all open), and then down 10mm.
