Alternative ways to code something like a table within a table? Connect and share knowledge within a single location that is structured and easy to search. 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. Okay so it may not be a bug with Merlin but rather with Repetier host. However, the problem is that the Z home has a defect in that it overwrites the X/Y home position to be the Z_SAFE_HOMING_[XY]_POINT be 0,0 again when it's at the center of the bed; so instead of the X/Y home begin at the corner of my bed with a correct value of 0,0, instead the X/Y home is at the center of my bed and it incorrectly sets the value to 0,0 again. Which distribution of marlin did you install? 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. Y homes to minimal Y-end stop. For best results getting help with configuration and troubleshooting, please use the following resources: After seeking help from the community, if the consensus points to a bug in Marlin, then you should post a bug report. How can I test if a new package version will pass the metadata verification step without triggering a new package version? 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? Have a question about this project? to your account. It is now only doing Z homing in the center of the bed again. For more information, please see our Please open a new issue for related bugs. Where . 1. @Ryan, I totally agree - these BL Touch probes are a major pain to get . @Trish Getting, changing and uploading is already described in another question, but very nice you have figured out to compile it on your board! You signed in with another tab or window. 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. I still would like to find a way to slow down the X movement when it goes to home Z. SKR 1.3 or 1.4 & MKS SGEN L Board Setup Tutorial with TMC2208 UART, Auto bed leveling - nozzle in center, not probe. Actually you should open an issue for Repetier Host (and If Z_SAFE_HOMING was enabled, and the bed properly dimensioned, it could be that the steps/mm are incorrectly defined. I've set Z_SafeHoming. How to make Ender 5 use BLTouch probe for Z homing? Well occasionally send you account related emails. -- | -- | -- | -- | -- 100, 100) where the Z homing should be # performed. i was trying to change the steps for my zaxis. yea its working now. Good to hear it works out! Sign up for a free GitHub account to open an issue and contact its maintainers and the community. 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. Does Chain Lightning deal damage to its original target first? . Already on GitHub? Software: Marlin 2.0.7 (newest release as of 10/5/2020) I have attached the configuration files if someone wants to review. After step 4 the X,Y,Z coordinates are still at 0,0,0 even though the axis moves to the center of the bed plus the offset values for hotend - z probe. Z. 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. 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. I have my offset to nozzle set to (0,-74,0) Settings I have set: define Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN 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 think this is my issue. Most people would expect to read about bootloaders and flashing now, and indeed that is an option. I followed multiple threads on this issue but not a single one solved my problem. 12 gauge wire for AC cooling unit that has as 30amp startup but runs on less than 10amp pull, How small stars help with planet formation. You have to in marlin have a probe enabled, Use probe as Z senor, the probe offset entered correctly and a type of bed leveling selected, as well as Z safe homing. There the sensor is activated and an offset is defined, this is only used for homing where z-homing takes place, i.e. I didn't know there is a marlin firmware available for smoothieboard! Please open a new issue for related bugs. How to determine chain length on a Brompton? That saves all data in a epr file and you can later use import eepsom settings to rewrite it. Settings I have set: In configuration_adv.h I have set the first probe location to be 25,25 from zero.

The working origin/print bed origin at 0,0,0 does not necessarily need to be the homing switch location. This is a consequence of enabling Z_SAFE_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. When you change the hardware (e.g. Issue crashing Z-axis when I home X or Y axes. #endif Cool that works as advertised. The nozzle position is 0/0 with my setting, theoretically. Below are my settings. 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. 2) indicating which files of a Firmware Configuration usually contain these commands and 3) mention that one usually uses an arduino as Bootloader to flash new firmware and link to a tutorial for this. 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. rev2023.4.17.43393. This parameter must be provided. Equipment: Can I safely add the Offset back just for the Z-Safe Homing to get a true Home Center the Bed. carriage), you need to re-calibrate the movement from the end stop location to the origin of the bed. -- | -- | -- | -- | -- X0 Y0 Z0 at this point. Should I close or leave this ticket open? This issue has been automatically locked since there has not been any recent activity after it was closed. 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! From this post: If you see it in eeprom editor just change them. This means, that any Y command will be off by this distance. 2) How to implement the changes via Repetier Host? This prevents your Z homing from occuring without prior X and Y homing. [safe_z_home] home_xy_position: # A X, Y coordinate (e.g. Privacy Policy. How to turn off zsh save/restore session in Terminal.app, YA scifi novel where kids escape a boarding school, in a hollowed out asteroid. X, Y, and Z coordinates get assigned a value of 0.

Repatier can't home, Pronter runs out of memory for my 14-18 hour prints :(. G28 How can I make the following table quickly? Worse is if I give it a positive distance it will overrun its axis depending on the value I give it. So, let's open your Marlin.ino with arduino and find the X_MIN_POS (CTRL+F > X_MIN_POS > Search all sketches). It tries to home Z in the 0,0 corner instead. It only takes a minute to sign up. Bed size is entered correctly. homing all and z-homing. I have them detailed in my Marlin guide. 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. However, Christian did figure out that the Sanguino set to an ATmega 1284P 16bit does work. Does your printer home Z at the wrong location? With these settings we were able to compile the settings. By default the values were X_Center and Y_Center. #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. -- | -- | -- | -- | -- Seems like it would be a good idea to bullet proof this behavior in the firmware. What screws can be used with Aluminum windows? This way any oozing that might happen while the extruder heats up will be outside of the bed. When I do a G28, it correctly does the X, then Y, but now the Z is not done in the center of bed (I have bltouch) and the speed/noise from the Z axis is much higher. Configurations.zip. 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. You signed in with another tab or window. IT'S WORKING!! *. The text was updated successfully, but these errors were encountered: So if you run G29 does it try and start probing the middle of the bed first? 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!

Almost there with my settings, I am now trying to find a "non macro" solution to this issue: I am using sensorless homing, so homing_retract_dist is not an option, now, when Homing XY or Homing All, I would like the X axis to move by 10-15mm after "hitting" the virtual endstop, to prevent him of flirting with the Z axis rods and ledscrew support when travelling his way to home Y. -- | -- | -- | -- | -- 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. SKR 1.3, 1.4 & MKS SGEN L Board Setup Tutorial with TMC2208 UART. You just have to consider your own offset. 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. You do not have the required permissions to view the files attached to this post. I tried setting absolute values here, I've tried doing ( (X_min_pos + X_max_pos) / 2). // - Position the probe in a defined XY point before Z Homing when homing all axis (G28) Is there a way to use any communication without a CPU? When the nozzle is in the center all other dimensions are correct also. I'm closing (remove if possible), then you have to describe the problem correctly. @alexborro I concur, SD printing is more teh happy. My information on the homing point relates to the nozzle, not the sensor. Sign in 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. I do not have, you should possibly retract the filament before probing Z to prevent oozing. Otherwise it could still bne using the old EEPROM config, which is the two config files in marlin. How to make Ender 5 use BLTouch probe for Z homing?
