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? With a G29 command, the sensor is off the front side of the bed and the nozzle is where I want the sensor to be. Privacy Policy. Alex. What sort of contractor retrofits kitchen exhaust ducts in the US? http://forum.repetier.com/discussion/463/g28-and-g29-commands-need-to-issue-m114, Now to look into me using another program. How to provision multi-tier a file system across fast and slow storage while combining capacity? #define Z_SAFE_HOMING_Y_POINT (Y_MAX_LENGTH/2) // Y point for Z homing when homing all axis (G28) #endif. 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. The printer knows this is (100,100,0) and is not mistakenly thinking it is (0,0,0). If that doesn't make any sense, just use the G-Code above and you should accomplish the same goal. #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. That saves all data in a epr file and you can later use import eepsom settings to rewrite it. Do you recommend to subtract the distance between the probe and the extruder nozzle and modify the Z_SAFE_HOMING_X_POINT value accordingly or there is a smarter way to input that distance in an initialization stage of the code? It tries to home Z in the 0,0 corner instead. Extends the stepping routines to move multiple steppers in proportion to the mix. Printing a large square on the heat bed will therefore give you a good impression of the offset of the nozzle due to your new carriage design. -- | -- | -- | -- | -- 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. Is the amplitude of a wave affected by the Doppler effect? (G28) #define Z_SAFE_HOMING_Y_POINT (Y_MAX_LENGTH/2) // Y point for Z homing when homing all axis (G28) . Makes me think something else is wrong there. Than it would need to be after both G28 and G29. So, let's open your Marlin.ino with arduino and find the X_MIN_POS (CTRL+F > X_MIN_POS > Search all sketches). This is useful if the toolhead, for example has to move to the center of the bed before Z can be homed. (this was working before), 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. For more information, please see our 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. //section machine // The size of the printable area #define X_BED_SIZE 400 // - If stepper drivers timeout, it will need X and Y homing again before Z homing #define Z_SAFE_HOMING #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). This issue has been automatically locked since there has not been any recent activity after it was closed. In your slicer go to the "before" section of G-Code and type in the relevant codes. Worse is if I give it a positive distance it will overrun its axis depending on the value I give it. -- | -- | -- | -- | --. Issue crashing Z-axis when I home X or Y axes. X and Y move at the same time to position the Z-endstop probe to the center of the bed. The nozzle position is 0/0 with my setting, theoretically.

This issue has been automatically locked since there has not been any recent activity after it was closed. 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. In the later case, you need to put the folder Marlin-?.?.X.ZIP/Marlin-?. Equipment: 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.

Connect and share knowledge within a single location that is structured and easy to search. It's not going to the center. 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. When you change the hardware (e.g. Creality offers the firmware on their website as a .hex file - which is hard to edit. In repetier-host it gives real-time X,Y,Z corrdinates. By default the values were X_Center and Y_Center. * Z Safe Homing * * Enable this option to avoid homing with a Z probe outside the bed area. 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. // - Allow Z homing only after X and Y homing AND stepper drivers still enabled This acts as if the Y offset for the probe is being ignored. Well occasionally send you account related emails. HSK6 (H61329) Q.69 about "" vs. "": How can we conclude the correct answer is 3.?

Well occasionally send you account related emails. -- | -- | -- | -- | -- I have to turn off power or it would hit my print bed. I thought I could have some edge value causing the firmware to ignore the -74 offset, so I adjusted this to -15 to test and see if the nozzle would be 15mm off of center. Okay so it may not be a bug with Merlin but rather with Repetier host. It should already have homing codes so just add in. just had to pretty much reverse engineer parts of the ender3 XD.
