By clicking “Sign up for GitHub”, you agree to our terms of service and As a side-effect, X and Y homing are required before Z homing. In my snapshot, the offending line was 1953 in Marlin_main.cpp. From a clean fir Asking for help, clarification, or responding to other answers. Ok. I'm using the Marlin firmware (1.1.0-RC7 - 31 July 2016) for a 3d printer. I don't know what it means specifically by "homing_feedrate_mm_m array instead". The printer knows this is (100,100,0) and is not mistakenly thinking it is (0,0,0). 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. Help needed : Marlin z axis homing speed settings. Being a derivative fro Marlin firmware, the bed leveling speed in between probes can also be easily set in G-code. Running Marlin 1.1.2, printing from Octoprint on Linux PC. I can safely rehome X and Y, but when I try to rehome Z the print head moves to the center of the plate, which of course would cause a collision with the model. When the z axis homes , it touches the endstop and moves up and homes again , but when moving down to home the second time , it moves extremely slowly , it … Stack Exchange network consists of 176 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. 4mm/s / 20 = 0.2mm/s.

I then set Z at zero, G92 Z0. Having a seam there isn't a problem. With a retract of just 2mm this takes 10 seconds. If stepper drivers time out, X and Y homing will be required again. I already have tried changing Z max feedrate and Z homing feedrate without noticing any major change in z speed. fly wheels)? Will try again to verify. How far would we have to travel to make all of our familiar constellations unrecognisable? // - Prevent Z homing when the Z probe is outside bed area. Without this, you may accidentally miss the bed when homing Z. With the plate lowered and the print well out of harm's way, I homed X and Y. This mess in speeds is pissing me off. I don't have another type of printer besides Delta but from what I hear homing is kind of...opposite on other types I'm not sure I fully understand it yet until I build one. The reason I use Z-max for homing is so that when i issue a Home it will pull the spindle up off the work area, which is especially needed before homing XY – I have Marlin set to home to Z first, then XY. // // With this feature enabled: // // - Allow Z homing only after X and Y homing AND stepper drivers still enabled.

I will go into as much detail as possible but please keep in mind that marlin is constantly being developed and changes can lead to a setting being named differently, a file being renamed and so on. All fails MathJax reference. it is funny because this section is in a else Brackets so in a nut shell it's saying Homing is required before G29, M48, and some other procedures.. I'm currently using Marlin firmware (1.1.0-RC7 - 31 July 2016) and would like to experiment with print speed. #define Z_SAFE_HOMING … Are those Jesus' half brothers mentioned in Acts 1:14? Then moved X10 Y0, a convenient place to work. They're just all the same on mine because of the way deltas work. Thank you TechMasterJoe! Using DSolve to find y[x] for a second-order differential equation. // - Prevent Z homing when the Z probe is outside bed area. There is no differentiation between the x/y axis homing speed and the z axis speed. I then set Z at zero, G92 Z0. Movement settings Define the number of axis. Why is this a correct sentence: "Iūlius nōn sōlus, sed cum magnā familiā habitat"? You signed in with another tab or window. 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. G29 seems to somewhat randomly leave the z-probe down after the last probe. And a 11 foot tall delta? How to calculate charge analysis for a molecule. I can't wrap my mind around what I need to do here. After I changed my extruder, Please see: [forums.reprap.org] my Z axis homing speed drooped to almost 0. #define Z_CLEARANCE_BETWEEN_PROBES 3. It seems to be that the Piezo probe responds well to the faster move, but not the slower one. #define Z_PROBE_SPEED_FAST HOMING_FEEDRATE_Z. FYI for the OP: G0 is a rapid move, G1 is a feed move and you can program them with different rates, but a lot of 3D printers seem to treat them the same. Now the printer seems to be of two minds when it comes to finding the origin. - 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 . There is no differentiation between the x/y axis homing speed and the z axis speed. OK. This causes problems with many printers as their z-axis couldn't move that fast. Without this option enabled the nozzle will crash into the bed when homing. // - If stepper drivers time out, it will need X and Y homing again before Z homing. // - Move the Z probe (or nozzle) to a defined XY point before Z Homing when homing all axes (G28). change to " feedrate = homing_feedrate[Z_AXIS]; ". It is the total number of axis (3) plus the number of extruders (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. To increase the homing speed, increase HOMING_FEEDRATE_XY from (20*60) to (40*60) and HOMING_FEEDRATE_Z … 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. So you take your 4mm/s / 60 which makes it so slow. 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. This feature is so sensitive that it can actually take the place of traditional endstops. When the z axis homes , it touches the endstop and moves up and homes again , but when moving down to home the second time , it moves extremely slowly , it … Successfully merging a pull request may close this issue. When I run G28 with no arguments, homing speeds are as expected. homing feed rate. Currently the printing is not perfect due to slight inaccuracies in movements along the x and y axis. Uncomment Z_SAFE_HOMING. I have just checked it and @Wurstnase is correct. To learn more, see our tips on writing great answers. Homing feed rate. It travels up to the endstops horribly slow. edited code to call homing feedrate for Z axiz for more control 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). Why can't I move files from my Ubuntu desktop to other folders? @section extras I've been trying to fix an issue with my Y homing function for quite some time. If homing is needed the LCD will blink the X Y Z indicators. The feedrate is in mm per minute. I use pronterface to do all my testing. To know this would be helpful in setting up a piezo z probe. Re-homing Z: trouble resuming a print, what if I can't re-home? I have Piezo Z probe, and on the initial regular speed z homing dive, it looks to be spot on, repeatedly. 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. The text was updated successfully, but these errors were encountered: Check out HOMING_FEEDRATE in Configuration.h and in Configuration_adv.h. This is the moving speed of the axis when homing in [mm/min]. (BTW I use min limit switches for my XY also – ) I found that in Marlin the G30 command does EXACTLY what i wanted. I set relative positioning on, G91, and moved Z up toward the print head until a business card was firmly clamped between the head and the plate. Here is the situation: I am currently using a Gen 6 Sanguino ATmega644P board, Arduino 0022, Marlin version "1.0.0 Beta 1". https://github.com/MarlinFirmware/Marlin/blob/Development/Marlin/Marlin_main.cpp#L1953, https://github.com/MarlinFirmware/Marlin/blob/Development/Marlin/Marlin_main.cpp#L1820. // - Allow Z homing only after X and Y homing AND stepper drivers still enabled. I suppose if that's true, then I could just shave off the new layers and reset zero a couple of layers tighter. I shaved off the new layers (having a kiridashi really helped there) and re-zero'd, but this time, after doing so I entered my initial Z value so that the nozzle touched the model and adjusted from there. UPDATE TESTED works good now, seach marlin_main.cpp for " Z_RAISE_BEFORE_HOMING " // - Move the Z probe (or nozzle) to a defined XY point before Z Homing when homing all axes (G28). I would sincerely appreciate any help. #define NUM_AXIS 4. Benefits Reduced chance of physical / endstop damage on Creality printers. This prevents your Z homing from occuring without prior X and Y homing. - 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 . I'm not sure what firmware this board runs, but Marlin has the capability to do a "Z_SAFE_HOMING". After homing the Z, I think it is safe to think that the z position of the probing points shouldn't be higher than 1mm of the point used for the z homing. The rest of the steps for resuming a print (editing the G-Code and what-not) are readily available in a dozen or more tutorials, so I won't cover that here. #define Z_PROBE_SPEED_FAST HOMING_FEEDRATE_Z. I uploaded a ... Z homing issue after Marlin firmware update January 14, 2014 09:08AM Registered: 7 years ago Posts: 553 There may be homing acceleration in Adv_config.h, I dont quite remember but I know there were a few different settings located there. I have just open an issue to discuss that: #1791. Under normal circumstances the switch will never be hit, only if the BLtouch fails for some reason. Only the first raise is painfully slow. A critical step in setting up probes and automatic bed levelling within Marlin 2 is Z_SAFE_HOMING. Being a derivative fro Marlin firmware, the bed leveling speed in between probes can also be easily set in G-code. 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. But on the slower second tap it does not trigger. | Many commercial 3D printers come with Marlin installed. Discussion. In the file Marlin_main.cpp I see in the process_next_command() function, there is a Log In Create A New Profile. Posted by Zarquon . G28 disables bed leveling. #define Z_PROBE_SPEED_SLOW (Z_PROBE_SPEED_FAST / 2) #define MULTIPLE_PROBING 2.

What's the earliest treatment of a post-apocalypse, with historical social structures, and remnant AI tech? So search and enable Z_SAFE_HOMING if using a BlTouch or probe. // - Allow Z homing only after X and Y homing AND stepper drivers still enabled. Helllz ya hehe. As the Creality printers use the same hardware across their models, this change can be applied to all models. // - Prevent Z homing when the Z probe is outside bed area. 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. 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. How to pull back an email that has already been sent? 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. This prevents your Z homing from occurring without prior X and Y homing. Apparently Marlin (or Octoprint? Or make it go the same speed as the initial tap? // - Allow Z homing only after X and Y homing AND stepper drivers still enabled. When this correction is correct in line 1953 https://github.com/MarlinFirmware/Marlin/blob/Development/Marlin/Marlin_main.cpp#L1953 Use this command to set the bump sensitivity for the X, Y, and Z stepper drivers. I found an occurrence of "feedrate = max_feedrate[Z_AXIS]" earlier in the same function (gcode_G28()), but that had no effect. That's interesting it must not be applying the same way for delta. If I run G29, again speeds are as expected. share | improve this answer | follow | answered Sep 6 '18 at 8:30. profesor79 profesor79. Everything seems to be at the rate I expect except that initial rise. Steps per mm Homing XY moves to the lower left as it always has, but homing Z moves not only to Z=0, but also to the center of the build plate. #define Z… With this change, the second probing speed for Z at G28 is the same as the first probing. This is the first time it's ever frozen mid-print and I think it's because I left Cura and several other Chrome tabs open. Follow-up: yep, left too much room. slower (half speed) decent until stop hit again. This is the moving speed of the axis when homing in [mm/min]. Or, barring that, some offset I can enter for Z so I can resume at the same height I started? Thats awesome. // - Prevent Z homing when the Z probe is outside bed area. im debugging now G28 Z0 ; Home Z. I believe that should accomplish what you're after. Making statements based on opinion; back them up with references or personal experience. Without this option enabled the nozzle will crash into the bed when homing. Discussion. Home > Firmware Folder > Firmware - Marlin > … From a clean fir feedrate for line_to_destination is feedrate/60. Without a doubt a particularly critical step in setting up probes and automatic bed levelling within Marlin 2 is Z_SAFE_HOMING. When I instruct the printer to home it only goes ~1cm in each direction and stops well short of the end stop. If stepper drivers time out, X and Y homing will be required again. Ender 5 Pro With BLTouch Marlin bugfix-2.0.x config - ender-5-pro.patch 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. Have a question about this project? Beekeeper. idk) will let you print without homing Z as long as it knows where zero is. idk) will let you print without homing Z as long as it knows where zero is. @AnHardt Sure, sure! 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. 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. How can i disable the second tap? This will be performed before any bed levelling procedure; Using Auto Bed leveling¶ Refer to Marlin's excellent Wiki on the subject. Reply Quote. privacy statement. I moved to print head to my desired X, Y, and Z positions and checked it against the model, which seemed to be right. @Wurstnase Forum List Message List New Topic. But I will try changing the HOMING_FEEDRATE to see which of the steps is affected. You’ll need to calibrate this later. Why do password requirements exist while limiting the upper character count? Is your printer supposed to home at Z0 normally? Using the given current, Marlin will move the Z axis (at homing speed) to the top plus a given extra distance. If you want to use PID to efficiently heat your bed, uncomment #define PIDTEMPBED. Hmm the only time that effect happens for me is if I try to move any axis...x, y, z, or an extruder before I home with just a normal G28. I moved to print head to my desired X, Y, and Z positions and checked it against the model, which seemed to be right. 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. When I run G28 with no arguments, homing speeds are as expected. Built latest Marlin (as of couple hours ago) for Printrboard on Simple Metal. Check with your vendor if you need source code for your specific machine. // Set to 3 or more for slow probes, averaging the results. I recently upgraded my prusa i3 firmware to a newer version of marlin. When the z axis homes , it touches the endstop and moves up and homes again , but when moving down to home the second time , it moves extremely slowly , it takes 1 minute to hit the endstop again. 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). Apparently Marlin (or Octoprint? Do rockets leave launch pad at full thrust? 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. // // #define Z_SAFE_HOMING # if ENABLED(Z_SAFE_HOMING) // #define Z_SAFE_HOMING Note I use a Delta but I believe these variables are in all setups. to your account. Without this, you may accidentally miss the bed when homing Z. I use pronterface to do all my testing. In the several tutorials I read on how to resume a print, they all assume that the printer - which in my case had a restart of its own - knows where Z is. #define XY_PROBE_SPEED 8000. Note that aesthetics aren't an issue: these are mechanical parts to all they need is to not snap in the middle. Use Z_STEPPER_AUTO_ALIGN instead. https://github.com/MarlinFirmware/Marlin/blob/Development/Marlin/Marlin_main.cpp#L1820? Speed seems to be the same/similar whether movement initiated from controller, from host buttons or with a G-command. I recently upgraded my prusa i3 firmware to a newer version of marlin. I kept the heat on for the bed so the print wouldn't shrink and break loose. Without this, you may accidentally miss the bed when homing Z. A command like G1 F1000 sets the feedrate for all subsequent moves. Notes. Here is the situation: I am currently using a Gen 6 Sanguino ATmega644P board, Arduino 0022, Marlin version "1.0.0 Beta 1". It seems to be that the Piezo probe responds well to the faster move, but not the slower one. Course Z is done much differently in a moving bed setup. Uncomment and set #define MANUAL_Z_HOME_POS -0.15; Uncomment #define Z_SAFE_HOMING. If you want to use PID to efficiently heat your bed, uncomment #define PIDTEMPBED. Is there a setting for this that I don't know about? max_feedrate[Z_AXIS] * 60 is that what it should be.#1790 Follow with M420 S to turn leveling on, or use RESTORE_LEVELING_AFTER_G28 to automatically keep leveling on after G28. Some TMC stepper drivers can detect when they bump into something that causes them to stop moving. Does all EM radiation consist of photons? We might get some questions why "Marlin homes slower than TH3D" Related Issues #12074 Can someone explain to me the line in marlin "#define HOMING_FEEDRATE_Z (20*60)" as it relates to changing the Z homing speed? i just built it as of the last 20mins for my i3 and can confirm the bug is real And you set it so Z0 is appropriate nozzle height. // - If stepper drivers time out, it will need X and Y homing again before Z homing. Report the current speed percentage factor if no parameter is specified. in config.h as it looks like the given speed is to high. Homing issues with Marlin. 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. This video come from https://www.youtube.com/user/fiverats/featured It‘s said black marlin can swim more than 100-130km/h？？ This command is deprecated. // Set to 2 for a fast/slow probe, using the second probe result. Without this, you may accidentally miss the bed when homing Z. I use Marlin/Ramps but, don’t use Estcam.
