Description Config Now it's possible to disable PROBE_OFFSET_START and use current probe.offset.z instead The set PROBE_OFFSET_WIZARD_XY_POS will be used for probing a z_offset_ref and for the nozzle/bed … G28 X Z ; Home the X and Z axes. How do I disable that? Or do I need to change something else entirely? See examples below. Right now, it auto homes correctly to the end stops in the back right, but 0,0 is in the Ender 3 location, front left. kill() called! Only problem left is when I auto home and it's probing the Z, it's too far forward and left instead of being near the center. The current position is adjusted to align to the new home offset values. Prusa i3 marlin homing to the centre of build plate, why? Hi and welcome to SE.3DP. The printer knows this is (100,100,0) and is not mistakenly thinking it is (0,0,0). Are those Jesus' half brothers mentioned in Acts 1:14? Is it my fitness level or my single-speed bicycle? I never changed my home dir.

Hi all, I've been lost in the swarm of setting available in the configuration.h file. If I changed the invert X and Y to false, and the directions to -1, would this move the origin back to the default Ender 5 home position? Homing should always send the extruder carriage toward the switches. Z Safe Homing isn’t 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. I do not have, you should possibly retract the filament before probing Z to prevent oozing. In configuration.h, line 866 (on Marlin RC8), remove the comments (by deleting the "//" at the beginning) for each axis you want to manually set a position for. As a side-effect, X and Y homing are required before Z homing. Could you expand upon your answer a little, by explaining what the additional code does and why it solves the issue? Steps to Reproduce. I installed a BLTouch bed leveling probe on my printer which uses Marlin 2.0.5.3. // - Prevent Z homing when the Z probe is outside bed area. Marlin indicates this by blinking question-marks in place of X, Y and Z on the LCD screen (v1.1.8 and older) or blinking ‘?’ in place of the coordinates besides X,Y and Z (Marlin v1.1.9 / v2.0.0 and newer).

As an Open Source project hosted on Github, Marlin is owned and maintained by the maker community. I also have an AM8, modified to my needs. This time about Motion Configuration . Marlin 2.0.7 BL.zip. And for any existing gcode files, that you don't want to reslice, you cam hand edit and change the "goto 0,0" instruction. If stepper drivers time out, X and Y homing will be required again. So I switched X and Y home to -1 since I wanted it to home at the minimum, not the maximum. This feature allows the driver to detect motor stalls under some circumstances. Reliable and precise, Marlin delivers outstanding print quality while keeping you in full control of the process. This set both my origin and auto home to the back right corner, like I wanted. With GCode based systems, you are given the option to send the homing command when LightBurn first connects. So I've spent the weekend installing a new Z axis and BLTouch, both of which required changes to the firmware (well, technically I could have just moved the knob 120,000 times to increase the Z steps to 1600). Then it moves to home X, and it tries to move the Z-axis up to Z_HOMING_HEIGHT, which is set from Z_CLEARANCE_BETWEEN_PROBES if that is defined (which it was for me, and it was 5). 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. Edit: Doh, the probe offsets are relative to the origin, so if my origin is now in the back right instead of front left, I just need to change the negative offsets to positive ones. This is going to be a, hopefully, complete tutorial on configuring Motion Control on 3D printers build on Ramps 1.4 using Marlin firmware. Currently the code is using XY_PROBE_SPEED, which is the speed to use when moving between points while … * * If you're also using the Probe for Z Homing, it's * highly recommended to enable Z_SAFE_HOMING also! The most-used form of this command is to home all axes: G28 ; Go to origin on all axes. A large number of various 3D printers is running on the popular Marlin firmware, which was initially configured for Ultimaker Original. 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. only the invert. My default Cura start G-code contained this sequence: However any oozing will still happen at the center of the build plate, which is a problem. On a Cartesian printer, if you use the G1 command with S1 parameter to perform a homing move on several axes simultaneously, each axis will continue moving until either the specified movement amount has been completed or the homing switch for that axis has been triggered. // - If stepper drivers time out, it will need X and Y homing again before Z homing.
