Have a question about this project? euclidian distance between points divided by time for move equals feedrate). In my Configuration.h i have #define Z_MIN_POS 0. Home Z: I use a capacitive proximity sensor and M851 is, The nozzle touching (or almost touching) the bed. privacy statement. Move to where we think Z height 0 is: G1 F60 Z0; Disable software end stops - Be careful! 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. By clicking “Sign up for GitHub”, you agree to our terms of service and The offset in X,Y, and Z are the values defined in the firmware (In Marlin Configuration.h). Any hint? Do you home with the probe? Now use the pronterface software to move Z lower until it grabs your test piece of paper. The value for X and Y can be quite coarse. 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 Super weird thing: I loaded new firmware to get this issue but going back with PR it persists. to your account. Now my Z doesn't go below 0 even if i have a negative z offset set by M851. It’s safer to leave Z as 0 here are calibrate this yourself later. Note: Slicers tend to override firmware feedrates! Isn't that the min value for Z ? 0.6 mm (0.6 mm is example, note your actual) Use this formula to determine your Z offset needed: e.g. #define Z_MAX_POS 190. @ejtagle I think I've found my issue cause. Z moves both directions (ok never goes below 0 but after a rise I can lower) marlin allow negative z, MARLIN FINANCIAL IS NOT LICENSED. 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. 0,0 is on left bottom of the Buildplate, as usual.

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.) 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. We’ll occasionally send you account related emails. Movement settings Define the number of axis. 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. If those adjustments are big enough, after homing all hardware endstops are free. Using the Creality BLTouch Kit bracket, mine is { -43, -9, 0 }. 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. Interrupts promptly may reset hit_state but live_state is set because of at least one micro is pressed. Homing feed rate. No abort so endstops are not cause. sequence example: Have a question about this project? 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. Instructions are in the comments. Is my understanding of Z_MIN_POS wrong? It’s safer to leave Z as 0 here are calibrate this yourself later. I think that hit_state and live_state should be reset after validate_homing_move and not inside. Been using marlin 1.1 but wanted newest auto leveling and other bells and whistles. Isn't that the min value for Z ? In CNC G-code G53 is a modifier. On cartesian I think this is not possible. EDIT: Re-checked and everything looks ok in this regard. 3 3 0 0 0 0 0. note the Z value (i.e 0.7mm) and subtract it from the initial value (2mm-0.7mm). Add DELTA style home adjustments in every case. $\begingroup$ No, the feedrate for the individual axes is calculated so that the total feedrate is 9000mm/s (e.g. Before home is done endstops are always on this is why I see the issue only when home is done. @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. 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). I'm not sure what's its purpose. Likely the error is about here (https://github.com/MarlinFirmware/Marlin/pull/3829/files#diff-1cb08de130a6ece2d1b5b9c37bcfef48R1295). On SCARA machines G0 does a fast non-linear move. So thats good. Coordinates are given in millimeters by default. Sign in So homing-validation on Delta will have to be ensured to happen only at the points where endstops are known to be triggered. Skip to # 5 if you're familar with Configuration.h in Marlin. I'm proceeding to try to understand why planner skip it, Of course M502 and M500 after every time I update firmware. In Marlin 1.1.0 and up, the physical boundaries are maintained. I have an FLSun 3D Cube, running off an MKS GEN V.1.4 main board. Endstops.enable(false) In earlier versions of Marlin G92 doesn’t update the software endstops, so it was unsupported to set coordinates outside these boundaries.

Successfully merging a pull request may close this issue. Don't know what is "DELTA style" since mine is cartesian and I never worked with delta printers. But when I home the axis, they move to the right/front insted of left/back. Specs: SKR1.3, TMC2130 Sensorless Homing, Marlin 2.0.5.3, Ender 3. The text was updated successfully, but these errors were encountered: @AnHardt the issue is not during home. 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. The Z_MIN_POS is -3 so the nozzle can move below Z0. What happens in my dual Z dual endstop (but I think this may be a problem for everyone): 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. (MarlinFirmware:RCBugFix, last update 15/05/2016). baricuda BARICUDA M126 - Baricuda 1 Open. In Marlin 2.x, they’re now combined in NOZZLE_TO_PROBE_OFFSET. For now I guess I have to make sure nothing breaks... @Blue-Marlin will you care to submit a patch for this bug ? 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. 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. # 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. Hmm ja. Edit: hit_on_purpose is ok and it works. You could experiment with the same idea to see if it fixes the issue for you. Thing Apps Enabled. 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. This means you can no longer use G92 to move below the bed, for example. The patch i meant only corrected to software endstops for G92. Delta homes far from bed and can move far from endstops. 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. my variable is or'ed with abort_current_block and reset on M119 call. This means you can no longer use G92 to move below the bed, for example. 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. #define Z_MIN_POS 0. If not please check if you have defined, I have #define min_software_endstops true in Configuration.h. Marlin 2.0 introduces an option to maintain a separate default feedrate for G0. move rise but doesn't lower. In earlier versions of Marlin G92 doesn't update the software endstops, so it was unsupported to set coordinates outside these boundaries. with a single search and very easily. 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. Isn't that the min value for Z? Are there other settings than Z_PROBE_OFFSET_FROM_EXTRUDER that affect bed leveling? Notes. X, Y axis move fine (to right and back when adding +10 on the axis). Thing Details Thing Files Apps Comments Makes Collections Remixes ... bug Marlin monoprice monoprice_ultimate Wanhao Wanhao_D6. Set Gap Between Nozzle And Bed Using G-Code, EEPROM & Marlin Firmware Does it make a difference if you make the test before or after G29? Endstops.enable_globally(true); My problem is with G38. Then do a G28 Z0 to move Z to the actual position of Z 0. Tried to implement latest Marlin on my reprappro with ramps 1.4. So I set both to 3. 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. Notes. Already on GitHub? This issue has been automatically locked since there has not been any recent activity after it was closed. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. I have a stationary Z Probe, but in Marlin it says Inductive probes need space to keep from triggering early. @AnHardt I think I don't understand (it's not the first time I misunderstand you, please be patient). That's how I have my printer set up, at least. @AnHardt I can move z up 50mm, then m119 (all open), and then down 10mm. Is my understanding of Z_MIN_POS wrong ? Still goes down to the same value as M851. Sign up for a free GitHub account to open an issue and contact its maintainers and the community. I see. It precedes a movement command (or other modifiers) on the same line. In Marlin 1.x, this was done with X, Y, and Z_PROBE_OFFSET_FROM_EXTRUDER. What must be done is to clear live_state at home end if and only if endstops are not "continuosly" tested. Units may be set to inches by G20. ... 1.0.0-beta encoder I2C_POSITION_ENCODERS M860-M869 - I2C Position Encoders. 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. https://github.com/MarlinFirmware/Marlin/pull/3829/files#diff-1cb08de130a6ece2d1b5b9c37bcfef48R1295, Fix bad movement in gcode_T when switching extruders. Trying G1 Z0 will show the Z probe endstop is hit and Z won't go any lower. Ender 5 Pro With BLTouch Marlin bugfix-2.0.x config - ender-5-pro.patch I am using Marlin 1.1.0-RC7. The current position is adjusted to align to the new home offset values. @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). privacy statement. See G54-G59.3 for workspace coordinate system. We’ll occasionally send you account related emails. Deltas do have home adjustments , not only for 1 axis of a pair, but 3 adjustments for all 3 of their axes. Place a piece of paper between the hotend and the print bed. Then you can do a M211 S0 to remove the safety measure for Z. This is a requirement for proper working software endstops anyway. 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. This effectively shifts the coordinate space in the negative direction. 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. I can imagine... Let me know if you need some help testing (when you have smth to test :D ) ... 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). Successfully merging a pull request may close this issue. In Marlin 1.x, this was done with X, Y and Z_PROBE_OFFSET_FROM_EXTRUDER. Using the Creality BLTouch Kit bracket, mine is { -43, -9, 0 }.
