Software: X | -- | -- | -- | --, Incorrect X/Y (0,0) due to z_safe_homing: Most people would expect to read about bootloaders and flashing now, and indeed that is an option. 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). 6.1 Homing Z should not plunge into work 6.2 Homing XY should attempt to lift cutter out of work piece; Ability to pause carve, move tool up/down (at least) to provide clearance for adjusting dust boot, then resume program where it left off (head should automatically return to where it was and continue) Now the problem is with step 4. @Trish Getting, changing and uploading is already described in another question, but very nice you have figured out to compile it on your board! In your slicer go to the "before" section of G-Code and type in the relevant codes. This is resulting in run away X, Y, and Z movements. What is the purpose of homing? which gives me X= 95 and Y = 84, But instead, by Z axis is homing on . -- | -- | -- | -- | -- If stepper drivers time out, X and Y homing will be required again. Marlin 2.0.7 (newest release as of 10/5/2020) Please open a new issue for related bugs. Apparently there is an EEPROM editor available (in Repetier Host). I'm not sure what firmware this board runs, but Marlin has the capability to do a "Z_SAFE_HOMING". This will result in two files: Of these two, the Marlin.ino.sanguino.hex is the interesting one for "direct flashing" via CURA. the file is from a folger tech 3 d printer. I have them detailed in my Marlin guide. Edit 2: Well I figured out the problem. When homing the printer, the hot end carriage will be instructed to hit the (mechanical or optical) end stops. Set up the new firmware with these base settings or adjust as needed. I have a printer with the following dimensions: L300 x W300 x H400. Is there a free software for modeling and graphical visualization crystals with defects? Now, either hack those into Repetier firmware or use a blank Marlin.ino and the Arduino IDE to customise it. How can I drop 15 V down to 3.7 V to drive a motor? By default the values were X_Center and Y_Center. 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 am trying to get the probe to be the center of the bed for Z home. -- | -- | -- | -- | -- X0 Y0 Z0 at this point. The printer knows this is (100,100,0) and is not mistakenly thinking it is (0,0,0). Please Help going nuts! . rev2023.4.17.43393. 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. 3D. Many thanks. In the configurations we grabbed the sketch file Configuration.h contains lines 786-789 (might differ): Adjust these till the wanted position is achieved - Repetier Host can help here to determine the right position. i was trying to change the steps for my zaxis. No matter what I try, X goes flying whenever it goes to home Z. How to determine chain length on a Brompton? During an AUTO HOME sequence, should the nozzle or probe be in the center of the bed if I have the offset set in the firmware? @Ryan, I totally agree - these BL Touch probes are a major pain to get . 1. Can we create two different filesystems on a single partition? 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. Ewald_IkemannApril 1, 2021, 6:15am #3 Thank you so much. // - Block Z homing only when the probe is outside bed area. Is there a way to use any communication without a CPU? While setting the probe up, I've watched countless tutorials and haven't had any luck. The nozzle goes to the zero point and the sensor is 74mm off the edge of the plate. at the end of G28.cpp, just before ui.refresh(); This moves the print head to X0, Y0 and leaves Z untouched after the homing procedure. I have described how you do that in. //section machine // The size of the printable area #define X_BED_SIZE 400 How do I stop this from happening? When I home X and Y it gets set to 0,0 (corner of my bed). 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. Software: Marlin 2.0.7 (newest release as of 10/5/2020) I have attached the configuration files if someone wants to review. Than it would need to be after both G28 and G29. Z sensor is a inductive proximity sensor. #define Z_SAFE_HOMING_X_POINT (X_BED_SIZE / 2) // X point for Z homing, #define Z_SAFE_HOMING_Y_POINT (Y_BED_SIZE / 2) // Y point for Z homing, #define HOMING_FEEDRATE_MM_M { (50*60), (50*60), (4*60) }, // Validate that endstops are triggered on homing moves. When I tried it with Pronter-face i observed different results. Sign in Anything in there not look right? It's the interpolation and X Y Z E microsteps that are moving the motors in a wrong way. In Marlin there is Z-Safe Homing it does not set the nozzle in the center of the bed on my 3D Printer though it move it fairly close. Now the homing point should be 0/0. Can dialogue be put in the same paragraph as action text? With these settings we were able to compile the settings. Use this file with the process starting at Step 2 here or use one of Greenonline's solutions to get the firmware flashed - no bootloader needed! #speed: 50.0 # Speed at which the toolhead is moved to the .

Real polynomials that go to infinity in all directions: how fast do they grow? I had an extra space in front of the negative sign, but this didn't change anything. -- | -- | -- | -- | -- To write the firmware yourself or using Repetier firmware, you need the old settings. G28 I'm not sure what firmware this board runs, but Marlin has the capability to do a "Z_SAFE_HOMING". Sign in Although its after G28 and not G29 :). One home X and Y and the other one Z which is equivalent too G28 XY and G28 Z 3dArnie: because now it does not home in safe homing center board not quite sure what that means? Well occasionally send you account related emails. Z . Privacy Policy. Unfortunately I can only find info on how to change offset of origin point. IT'S WORKING!!

Good to hear it works out! The nozzle is still center of the bed. * Example: `M851 Z-5` with a CLEARANCE of 4 => 9mm from bed to nozzle. Note that any arbitrary point on the heat bed can be used to re-calibrate this. Correct X/Y at 0,0 due to manual X and Y home. Okay so it may not be a bug with Merlin but rather with Repetier host. Well, let's start configuring our Marlin firmware to support BLTouch / 3DTouch sensors. If it is repetier-firmware based it will store changes in eeprom on pressing "ok". // - If stepper drivers timeout, it will need X and Y homing again before Z homing After battling this for a bit, I managed to get determine the Z-SAFE_HOMING sending to the center of the bed and setting coordinates to 0,0 there. X homes to minimal X-end stop. -- | -- | -- | -- | -- The idea of Z safe homing is that it is forced to home Z in the middle of the bed (bed size/2) so the inductive probe does not try to trigger in thin air. Can dialogue be put in the same paragraph as action text? How do I reconfigure the Home position to have an offset to the 0-positions gained from the limit switches? can one turn left and right at a red light with dual lane turns?

As in, when I press home x and home y, it hits the respective min endstops and then goes to x 100 and y 100. do you have marlin firmware installed? Center has been standard at marlin for some time. Now, we did set Tools>Board:> Sanguino and Tools>Processor:>ATmega1284 or ATmega1284P (16 MHz) It was also mandatory to have the U8glib.h for Arduino installed. However, Christian did figure out that the Sanguino set to an ATmega 1284P 16bit does work. Greenonline and I spent this evening hacking/reverse engineering the Ender3 to solve this. Enter G28 X, Y, and Z coordinates get assigned a value of 0. Accidental homing should be "safe". But as I had just figured out how to install firmware from .hex and so I wondered: Can't we make .hex files from our settings? #define Z_SAFE_HOMING // This feature is meant to avoid Z homing with probe outside the bed area. HSK6 (H61329) Q.69 about "" vs. "": How can we conclude the correct answer is 3.? 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. Z Safe Homing isnt needed if a Z endstop is used for homing, but it may also be enabled just to have XY always move to some custom position after homing. Not sure why it's doing this, but just noticed that with the nozzle at home location of 0,0, the LCD shows it as being at X: 224 and Y: 214. So, in Arduino IDE press Ctrl+Alt+S (or Sketch > Export Compiled Binary). . This prevents your Z homing from occuring without prior X and Y homing. How to set Home Offsets and Manual Home definitions in Marlin correctly? marlin has a default offset for the probe, so you should set them to 0 both. Have a question about this project? homing all and z-homing. Extends the stepping routines to move multiple steppers in proportion to the mix. If that doesn't make any sense, just use the G-Code above and you should accomplish the same goal. (G28) #define Z_SAFE_HOMING_Y_POINT (Y_MAX_LENGTH/2) // Y point for Z homing when homing all axis (G28) Note that if a probe is used, the offset of the probe to the nozzle center is taken into account, this implies that the probe is moved to the center, not the nozzle. I have a runaway problem. 3D Printing Stack Exchange is a question and answer site for 3D printing enthusiasts.

Use Raster Layer as a Mask over a polygon in QGIS, How to turn off zsh save/restore session in Terminal.app. 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. Adhesion issues with Ender 5 and BLTouch 1.3, Severe regression in print quality after adding Z probe, Weedo Tina2/Monoprice Cadet auto bed leveling: Sensor not moving down to touch the print bed. -- | -- | -- | -- | -- The code responsible for this is found in G28.cpp: I.e. #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). Equipment: X and Y move at the same time to position the Z-endstop probe to the center of the bed. As I explained in the previous article of Configure Marlin 2.0.3 from scratch, to activate the options you simply have to uncomment them.This is done by removing the two bars in front of each #define, this way the compiler can make use of them and add them to the final firmware.
