The printer knows this is (100,100,0) and is not mistakenly thinking it is (0,0,0). Notes. If I run G29, again speeds are as expected. Notes. The text was updated successfully, but these errors were encountered: Check out HOMING_FEEDRATE in Configuration.h and in Configuration_adv.h. look in same block for "feedrate = max_feedrate[Z_AXIS];" // - Move the Z probe (or nozzle) to a defined XY point before Z Homing when homing all axes (G28). But I will try changing the HOMING_FEEDRATE to see which of the steps is affected. Without this, you may accidentally miss the bed when homing Z. Homing speeds are just below the Steps per Unit, I believe, but I don't have it in front of me. and i have 8 start leadscrews for Z and can move well over 40mm/s, found it code expects Max Z feed rate in MM per min idk) will let you print without homing Z as long as it knows where zero is. Thanks for contributing an answer to 3D Printing Stack Exchange! // - Prevent Z homing when the Z probe is outside bed area. This feature is so sensitive that it can actually take the place of traditional endstops. still has another bug hiding 3rd print it started Z down on G29 tell it crashed so more then a few problems to be found so back to my 3-15-15 Dev dump that just works i got 117 parts to print i will do more debugging tomorrow almost done with my 11 foot tall delta. #define Z_SAFE_HOMING … I fear that I may have not zero'd down enough, so there will be a noticeable gap/weak spot, but I won't know that until I get more layers on than there are at this moment. I finally have working FW that properly compensates for the bed level, and homes within my lilfetime. Since this intentionally stalls the Z steppers, you should use the minimum current required to move the axis. max_feedrate[Z_AXIS] * 60 is that what it should be.#1790 feedrate for line_to_destination is feedrate/60. in config.h as it looks like the given speed is to high. why not in line 1820 Where did all the old discussions on Google Groups actually come from? I send M119 codes to the printer in Pronterface when holding the Z switch with my finger and get that the z axis is open. If homing is needed the LCD will blink the X Y Z indicators. I then set Z at zero, G92 Z0. Report the current speed percentage factor if no parameter is specified. UPDATE TESTED works good now, seach marlin_main.cpp for " Z_RAISE_BEFORE_HOMING " privacy statement. G28 disables bed leveling. Realistic task for teaching bit operations. This is the moving speed of the axis when homing in [mm/min]. Forum List Message List New Topic. I have just checked it and @Wurstnase is correct. Without this, you may accidentally miss the bed when homing Z. But on the slower second tap it does not trigger. Welcome! To learn more, see our tips on writing great answers. slower (half speed) decent until stop hit again. I can't wrap my mind around what I need to do here. With this change, the second probing speed for Z at G28 is the same as the first probing. I see. // - Move the Z probe (or nozzle) to a defined XY point before Z Homing when homing all axes (G28). mines been changed to {2,2,2} just for this test This causes problems with many printers as their z-axis couldn't move that fast. With a retract of just 2mm this takes 10 seconds. Homing on the Ender 3 with HOMING_FEEDRATE_XY set to 50*60 was shown (MarlinFirmware#12074) to cause the end-stop micro-switches to bottom out, causing the carriage for both X and Y axis to physically crash into the micro switch. I'm using the Marlin firmware (1.1.0-RC7 - 31 July 2016) for a 3d printer. Marlin 2.0 on the SKR 1.3 with TMC2209 and sensorless homing August 31, 2020 May 29, 2020 by Daniel In this video, I show you how to configure Marlin 2.0 for the SKR 1.3 mainboard with TMC2209 stepper drivers and sensorless homing. normal decent until stop hit Here is the situation: I am currently using a Gen 6 Sanguino ATmega644P board, Arduino 0022, Marlin version "1.0.0 Beta 1". Default for this setting puts the nozzle in the center of the bed for G28Z, but you can define a corner offset if you wish. I found an occurrence of "feedrate = max_feedrate[Z_AXIS]" earlier in the same function (gcode_G28()), but that had no effect. // - Prevent Z homing when the Z probe is outside bed area. Help needed : Marlin z axis homing speed settings. Homing issues with Marlin. Zarquon. Help needed : Marlin z axis homing speed settings. Uncomment and set #define MANUAL_Z_HOME_POS -0.15; Uncomment #define Z_SAFE_HOMING. Homing feed rate.

White neutral wire wirenutted to black hot. // - Move the Z probe (or nozzle) to a defined XY point before Z Homing when homing all axes (G28). I'm trying to change the feedrate for speed along the xy axis whilst the printer is in operation to make sure the printer stops on time and prints accurately. Homing is required before G29, M48, and some other procedures.. Is there a setting for this that I don't know about? #define Z_PROBE_OFFSET_RANGE_MIN -5. It only takes a minute to sign up. lower the moving speed of the Z-axis motor, search for . I have the X, Y, and Z coords of where I need to begin again, and I've deleted all the GCode to that point. Homing feedrate The homing feedrate is the speed at which the axis home, by default it's set to #define HOMING_FEEDRATE {50*60, 50*60, 5*60, 0} // set the homing speeds (mm/min) Between the {} are the axis x,y,z,extruder, where extruder never needs homing. #define Z_MIN_POS 0. // - If stepper drivers time out, it will need X and Y homing again before Z homing.

You signed in with another tab or window. // - Allow Z homing only after X and Y homing AND stepper drivers still enabled. #define Z_PROBE_SPEED_FAST HOMING_FEEDRATE_Z // défini en lignes 789 et suivantes // Feedrate (mm/m) for the "accurate" probe of each point #define Z_PROBE_SPEED_SLOW (Z_PROBE_SPEED_FAST / 2) // second palpage à vitesse réduite de moitié // The number of probes to perform at each point. After I changed my extruder, Please see: [forums.reprap.org] my Z axis homing speed drooped to almost 0. This slow rise does not occur if I issue G28 with no arguments, but since it then moves the extruder to the middle of the bed, I cannot issue G29 afterwards. Is there a way I can home Z without the head moving to center? It's actually a vanilla Kubuntu 18 PC whose only function is to manage the printer. I use Marlin/Ramps but, don’t use Estcam. If homing is needed the LCD will blink the X Y Z indicators. Disable 'double tap' z homing on marlin. #define Z_PROBE_SPEED_FAST HOMING_FEEDRATE_Z // Feedrate (mm/m) for the "accurate" probe of each point #define Z_PROBE_SPEED_SLOW (Z_PROBE_SPEED_FAST / 2) // The number of probes to perform at each point. Ender 5 Pro With BLTouch Marlin bugfix-2.0.x config - ender-5-pro.patch | Many commercial 3D printers come with Marlin installed. What is this about This post will give guidelines on how to flash your own marlin onto a Eryone Thinker S V2 (NOT the V1) or ER20 printer. - Increasing Z homing speed : fails too, in fact, the homeing speed in marlin is way faster of what I have tried with repetier - Loosing steps: I have seen motors loosing steps, but this is different, the motor gets stucked - reducing z-jerk: the original value is 0.3, I have lowered it to 0.2 and 0.1 . Discussion. Was able to make it happen, though I fear that I may have misjudged exactly where zero was, but we'll see in a few hours. Set speed percentage factor, aka “Feed Rate” which applies to all G-code-based moves in all (X, Y, Z, and E) axes. Homing issues with Marlin March 20, 2012 06:47PM Registered: 9 years ago Posts: 16 Hi, I'm trying to switch from sprinter to Marlin (RC2) and I'm running into issues with homing. Z Safe Homing prevents Z from homing when the probe (or nozzle) is outside bed area by moving to a defined XY point (by default, the middle of the bed) before Z Homing when homing all axes with G28. share | improve this answer | follow | answered Sep 6 '18 at 8:30. profesor79 profesor79. to your account. I'm currently using Marlin firmware (1.1.0-RC7 - 31 July 2016) and would like to experiment with print speed. Speed seems to be the same/similar whether movement initiated from controller, from host buttons or with a G-command. When this correction is correct in line 1953 https://github.com/MarlinFirmware/Marlin/blob/Development/Marlin/Marlin_main.cpp#L1953 - MarlinFirmware/Marlin If you really can't fix that, run octoprint on a dedicated rpi that you're not gaming or loading experimental kernel modules or whatever on. We might get some questions why "Marlin homes slower than TH3D" Related Issues #12074 This video come from https://www.youtube.com/user/fiverats/featured It‘s said black marlin can swim more than 100-130km/h?? I kept the heat on for the bed so the print wouldn't shrink and break loose. Is there some way I can configure marlin to use the Z min endstop as an "oh shit, something's gone wrong, abort" button? And a 11 foot tall delta? G-code G29 has a speed parameter: S: Set the XY travel speed between probe points (in units/min) From below (TH3D firmware) can be seen that a value of 12000 mm/min will speed up and is generally safe to use. Hello, I changed the version from 1.1.8 to 1.1.9. Ok. Steps per mm It seems to be that the Piezo probe responds well to the faster move, but not the slower one. Without this option enabled the nozzle will crash into the bed when homing. Apparently Marlin (or Octoprint? Can an exiting US president curtail access to Air Force One from the new president? To increase the homing speed, increase HOMING_FEEDRATE_XY from (20*60) to (40*60) and HOMING_FEEDRATE_Z from (4*60) to (8*60). #define Z_CLEARANCE_DEPLOY_PROBE 5 . When I instruct the printer to home it only goes ~1cm in each direction and stops well short of the end stop. When I'm homed and my carriages are all at the top of the towers and clicks the endstops...I have my manually set home Z of 367.55 so the firmware knows it can travel down Z that far. If you want to use PID to efficiently heat your bed, uncomment #define PIDTEMPBED. (BTW I use min limit switches for my XY also – ) I found that in Marlin the G30 command does EXACTLY what i wanted. All fails 4mm/s / 20 = 0.2mm/s. The feedrate is in mm per minute. To know this would be helpful in setting up a piezo z probe. Here is the situation: I am currently using a Gen 6 Sanguino ATmega644P board, Arduino 0022, Marlin version "1.0.0 Beta 1". Without this option enabled the nozzle will crash into the bed when homing. Reducing the homing speed prevents the switches from bottoming out. 1,900 1 1 gold badge 3 3 silver badges 22 22 bronze badges $\endgroup$ add a comment | 0 $\begingroup$ Looks like endstop signal for Z is inverted. Uncomment Z_SAFE_HOMING. X and Y work as they should. From a clean fir - Increasing Z homing speed : fails too, in fact, the homeing speed in marlin is way faster of what I have tried with repetier - Loosing steps: I have seen motors loosing steps, but this is different, the motor gets stucked - reducing z-jerk: the original value is 0.3, I have lowered it to 0.2 and 0.1 . Well the issue I'm having now is that after flashing the firmware (Marlin Firmware 1.1.9) and attempting to home, the z axis limit switch is unresponsive. How to pull back an email that has already been sent? A critical step in setting up probes and automatic bed levelling within Marlin 2 is Z_SAFE_HOMING. OK. Is it possible for planetary rings to be perpendicular (or near perpendicular) to the planet's orbit around the host star? Apparently Marlin (or Octoprint? As the Creality printers use the same hardware across their models, this change can be applied to all models. Set the max feedrate for one or more axes (in current units-per-second). Report the current speed percentage factor if no parameter is specified. In my snapshot, the offending line was 1953 in Marlin_main.cpp. Are those Jesus' half brothers mentioned in Acts 1:14? On my printer the Z-axis switch is over to the side of the frame holding the print bed, so I can home Z with the print head anywhere. // - If stepper drivers time out, it will need X and Y homing again before Z homing. #define Z_PROBE_SPEED_SLOW (Z_PROBE_SPEED_FAST / 2) #define MULTIPLE_PROBING 2. So you take your 4mm/s / 60 which makes it so slow. The Creality printers use the minimum current required to move the axis when homing.!
