I did try to manually set the bed center position to no luck. We will need at least 1-2 hours with the computer and printer to try and determine what the issue is and come up with a solution. Now open the Marlin.ino in Arduino IDE. 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. Yes, this is because Repetier Host doesn't know where the extruder is. Found I did not have #define USE_PROBE_FOR_Z_HOMING set correctly. Connect and share knowledge within a single location that is structured and easy to search. It's not going to the center. 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). HSK6 (H61329) Q.69 about "" vs. "": How can we conclude the correct answer is 3.? How small stars help with planet formation. It was also mandatory to have the U8glib.h for Arduino installed. one from Christian, a German maker also known as "Chaos-Drucker"), we need to first adjust them as needed to fit our needs and then compile them properly (next step!). The best answers are voted up and rise to the top, Not the answer you're looking for? (As noted on this page.) Edit 2: Well I figured out the problem. Z axis moves downwards until Z-endstop switch hits bed. #1502 (comment) G28 My Y center is a bit off as well. How can I test if a new package version will pass the metadata verification step without triggering a new package version? From this post: If you see it in eeprom editor just change them. It's quite fast and loud, when it's otherwise silent. privacy statement. Repatier can't home, Pronter runs out of memory for my 14-18 hour prints :(. Is the amplitude of a wave affected by the Doppler effect? In repetier-host it gives real-time X,Y,Z corrdinates. However, Christian did figure out that the Sanguino set to an ATmega 1284P 16bit does work. It only takes a minute to sign up. Please open a new issue for related bugs. Greenonline also wrote about this in his blog. Already on GitHub? homing all and z-homing. Z_SAFE_HOMING not working I hit the home button and X and Y home in the lower left corner as they should, but homing Z does not move to center of bed. Learn more about Stack Overflow the company, and our products. EDIT: To prevent the Z endstop on a Voron 0 from triggering while the first layer prints, it's good practice if the Z endstop is positioned such that the nozzle ha. Prints I start now are still centered as long as I don't use G29. I have my offset to nozzle set to (0,-74,0) Settings I have set: define Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN Enable DIRECT_MIXING_IN_G1 for Pia Taubert's reference implementation or in external link Bed center calibration. Sign in IT'S WORKING!! Which slicer do you use? Now on to getting the abl to work First attempt, the probe is off the bed to the side despite having the offset and margin set. oh god, I just realized how much I learned in the last 1.5 years about firmware back then I was a noob, now I instruct on how to do this by pointing back to this question! This acts as if the Y offset for the probe is being ignored. Sign in the centre of the bed is not where Marlin thinks it is. G0 X100 Y100 F6000 ; Go to X100,Y100 at 100mm/s Well occasionally send you account related emails. This parameter must be provided. This issue has been automatically locked since there has not been any recent activity after it was closed. I needed to edit the steps/mm for the x/y axis. You signed in with another tab or window.

Stack Exchange network consists of 181 Q&A communities including Stack Overflow, the largest, most trusted online community for developers to learn, share their knowledge, and build their careers. If I change just X to 110, it goes flying to 0. You have to use those, every time. E.g. to your account. If you have a capacitive sensor, electro-mechanical, or just mechanical sensor for Z, you can search for that in "Configuration.h", uncomment to enable it and then upload the firmware to the board. Without this, you may accidentally miss the bed when homing Z. Extends the stepping routines to move multiple steppers in proportion to the mix. The only comment is that it centers the BL TOUCH probe instead of the extruder nozzle. Now that we have our Configuration files (in the end we pretty much skipped step 1 and grabbed a fitting (German!) Hi, when i do G28 it Homes x and y but then the nozzle starts just moving down and not going to the middle of the bed maybe someone can help please. The hardest step with the Ender3 was to get the code to actually compile, as it uses an ATmega1284P 16Bit which isn't supported by Arduino natively. This prevents your Z homing from occuring without prior X and Y homing. Well occasionally send you account related emails. The working origin/print bed origin at 0,0,0 does not necessarily need to be the homing switch location. its is a old file enven in 1.6 is says it was from a previous version . Repatier can't home, Pronter When I tried it with Pronter-face i observed different results. Kind of annoying, as you can imagine. #define Z_SAFE_HOMING_Y_POINT Y_CENTER // Y point for Z homing Wow! Ticket opened: http://forum.repetier.com/discussion/463/g28-and-g29-commands-need-to-issue-m114, Now to look into me using another program. For the printer to know the origin of the bed, offsets are defined in the firmware from the end stop locations to the actual origin of the heat bed. Hi and welcome to SE.3DP. I have my offset to nozzle set to (0,-74,0) Site design / logo 2023 Stack Exchange Inc; user contributions licensed under CC BY-SA. #define Z_SAFE_HOMING #if ENABLED(Z_SAFE_HOMING) #define Z_SAFE_HOMING_X_POINT ((X_MIN_POS + X_MAX_POS) / 2) . I am able to get it working minus the BLTouch. I think this is my issue. News and information related to the Marlin Firmware used on many 3D printers around the world. I found it. When I home X and Y it gets set to 0,0 (corner of my bed). Unfortunately, the same issue is still happening. Software: "". As a side-effect, X and Y homing are required before Z homing. Greenonline and I spent this evening hacking/reverse engineering the Ender3 to solve this. SKR 1.3, 1.4 & MKS SGEN L Board Setup Tutorial with TMC2208 UART. I tried setting it back to X/Y_center and changed the nozzle offset back to the default 10,10 and it doesn't move and says that probe is below bed, same if I set offset to 0,0. As I want to change to an e3D v6, which has a diameter of 22mm, I will have to move out some distance (ca. Now the printer seems to be of two minds when it comes to finding the origin. Although its after G28 and not G29 :). Could you expand upon your answer a little, by explaining what the additional code does and why it solves the issue? Z sensor is a inductive proximity sensor. Even though the X and Y moved the X,Y coordinates were not updated. Z safe homing does not home to the center of the build plate. . The values set here apply over and above any (negative) * probe Z Offset set with Z_PROBE_OFFSET_FROM_EXTRUDER, M851, or the LCD. If i only do it after G29 You can close it. At this point if I were to try and move the X or Y in a negative distance the software prevents it because it sees the axis at 0,0. When you issue a plain "G28", it'll home X/Y, then move the nozzle to the middle of the bed (plus offsets if you have them defined) before homing Z. What it's doing is when I auto home, it homes X/Y, then it should put the probe in the center (110,110,0) but instead it violently flys to X0 and Y comes in some. Isolating the Bug The only things that seem consistent with the homing bug happening are: AMD based computer used to compile the firmware 2560 Board - Usually the Creality V2.X boards that come in the Ender 5 Plus Well, let's start configuring our Marlin firmware to support BLTouch / 3DTouch sensors. 2) How to implement the changes via Repetier Host? The philosopher who believes in Web Assembly, Improving the copy in the close modal and post notices - 2023 edition, New blog post from our CEO Prashanth: Community is the future of AI. Thanks for the advice. yea its working now. The 3 point auto leveling was working intermittently and the GRID auto level would appear to home, but would not center the probe in the bed. //section machine // The size of the printable area #define X_BED_SIZE 400 When homing the printer, the hot end carriage will be instructed to hit the (mechanical or optical) end stops. X&Y axes home (fore some reason the X axes des not do the second slower homing procedure, I don't know if it's related) But there is an option in marlin, as morganlowe describes. I appreciate any assistance I can get on this as I am not able to activate auto homing until the offset issue for the Y is corrected. I have attached the configuration files if someone wants to review. As a side-effect, X and Y homing are required before Z homing. So, let's open your Marlin.ino with arduino and find the X_MIN_POS (CTRL+F > X_MIN_POS > Search all sketches).

Center has been standard at marlin for some time. The nozzle goes to 25,25 for the first probe spot, which does not work. X0 Y0 Z0 at this point. Accidental homing should be "safe". X homes to minimal X-end stop. This is resulting in run away X, Y, and Z movements. Most people would expect to read about bootloaders and flashing now, and indeed that is an option. Reddit and its partners use cookies and similar technologies to provide you with a better experience. Creality offers the firmware on their website as a .hex file - which is hard to edit. G28 X&Y axes home (fore some reason the X axes des not do the second slower homing procedure, I don't know if it's related) Then the Z axes home in the same position, not going to the center. The sensor is working and will set Z height correctly if I don't run G29 for a print, but I need to manually adjust to level the bed still. -- | -- | -- | -- | -- Digging further into the neither world here, I done a g28 X Y from console, it homed just fine according to m114: X:-18.0000 Y:-10.0000 Z:10.0000 E:0.0000 Count X:-1440 Y:-1000 Z:4000, X:224.0000 Y:214.0000 Z:10.0000 E:0.0000 Count X:17920 Y:21400 Z:4000.

My nozzle hit the bed pretty strongly on my first try (the bltouch still triggers the Zmin if I do it with my finger) Here are my configuration . "#if ENABLED (Z_SAFE_HOMING), They would have to change this e.g. If stepper drivers time out, X and Y homing will be required again. Optional support for Repetier Firmware M163, M164, and virtual extruder. Note that, if you cannot or will not flash new firmware, an alternative solution exists to set new incremental offset values using the M206 command IF your current firmware supports this. This is for version Malrin-1.0.2. #if ENABLED(Z_SAFE_HOMING) #define Z_SAFE_HOMING_X_POINT ((X_BED_SIZE) / 2) // X point for Z homing when homing all axes (G28). My sensor is 74mm in front of the nozzle and centered left/right. how do i add the file? Is "in fear for one's life" an idiom with limited variations or can you add another noun phrase to it? Should the alternative hypothesis always be the research hypothesis? I'm closing (remove if possible), then you have to describe the problem correctly. more PCs, no more USB disconnections and so on. You just have to consider your own offset. Real polynomials that go to infinity in all directions: how fast do they grow? Z.
