Can you replicate what you think homing sequence should be and see if it does the same thing? What is when you bed is on the maximum position? X homes to minimal X-end stop. that is what I am talking about. currently homing behaves like: move x 10 home x move y 10 home y move z10 home z. this could be inproved by nesting the … 9 months ago. We’ll occasionally send you account related emails. If you want to attach your Marlin_main.cpp file, I can look to see if you need to patch it so that you can use Z_min for your probe.-Jay On Tuesday, January 28, 2014 8:25:56 PM UTC-6, Ray Cheng wrote: Hi Jay, So I made the change with the Zmin to -1 in pin.h. Reply Quote. A comprehensive LCD menu system for UBL is coming soon. If you have your axis at the right end (for example) and try to move right ("move X +10") you will get a loud grinding sound as the motor torque fails to move the axis and the motor slips out of its magnetic hold. Homing sequences are typically used as building blocks in testing problems with no reset. if you rely on a probe as a min sensor, maybe a max sensor is handy. Sign in The head then went to Z safe home position in the middle of the bed and the Z axis moved as though homing but even after the Z probe triggered, it continued to ascend, nearly jacking the print carriage off the gantry before I could reach the power switch. The position that the joint will go to upon completion of the homing sequence. Today I wanted to switch back to latest dev version of repetier, coming from marlin, but doesn't like it as much as repetier. ... Use homing sequence with preheat as these allow to set a probing position as well that would allow activating z probe. The X axis hits the endstop abruptly, whilst the Y endstop is very soft. The text was updated successfully, but these errors were encountered: I have been thinking of something similar because almost no one wants to home XY while Z is touching the bed. Go to step 7 to test the new settings. Already on GitHub? Your printer doesn't know the position until it's homed. I didn’t actually have the endstops mounted and was triggering them with my hand. I do see this as a bug, so why disable this behaviour? I have a coreXY printer in which the X endstop is on the carriage, and the y endstop is on the body. This sounds like its more of an issue with your user interface of choice, since @galexander1 mentioned a way to do it with Gcode. Okay, figured it out. Home; About Us. When using SENSORLESS_HOMING with TMC2209 drivers. You can add in other dimensions at the same time: G1 X-10 Y-10 F600 G1 X0 Y0 F300 G1 X-10 Y-10 F300. doing some mill type work with a sharpie, i noticed that the marlin 1.0.0 firmwar hase some issues with the order of things in homing. privacy statement. But, there is a way, that you can click the x-home or y-home buttons and those will home, but, the Marlin software prevents z homing if the probe is out of the bed area. Get the SourceForge newsletter. #define DEACTIVATE_SERVOS_AFTER_MOVE This means the system needs first to establish its starting point of the physical (machine) coordinate system, a process called Homing. What interface separates x-home from y-home? However, instead of moving all axes away from the endstops before homing —which will lead to grinding in many cases— we should first home Z, then move Z away from the bed (if it's a min endstop), and then home XY last. Sign in yes, I have tried the feature for example g28 x0 y0 homes x first, g28 y0 x0 homes y first. I will go into as much detail as possible but please keep in mind that marlin is constantly being developed and changes can lead to a setting being named differently, a file being renamed and so on. The z works correctly with Pronterface or when I use the mechanical z stop and disable BLtouch. Denn vor knapp 3 Stunden wurde ein „Big Update“ veröffentlicht und Marlin steht ab sofort in Version 2.0.6 zum Download bereit. If the main issue remains, please comment. #endif 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 … Marlin also has pretty much out of the box support for 2 drivers feeding 2 motors on Y which we use for out long axis because it has 2 motors. Now the printer seems to be of two minds when it comes to finding the origin. If the stepper re-energizes and starts moving it’s more likely to be a software issue. The Unified Bed Leveling (UBL) system is a superset of the previous leveling systems.. You signed in with another tab or window. In all cases of homing, always y homes first. Have a question about this project? G28 disables bed leveling. Successfully merging a pull request may close this issue. Put it in your slicer's G-code prologue. If the homing speed is high, it might get a little bit of error, so it backs off a few mm and tries again at a slower speed. Y homes to minimal Y-end stop. Is there a setting on Marlin to raise Z before homing XY? The text was updated successfully, but these errors were encountered: @rupin FWIW, you can do this with "G28 Z\nG28 Y\nG28 X\n". Guten Morgen in die große weite Welt und diesen Tag möchten wir mit einem Artikel rund um die neue Marlin Software starten. that is what I am talking about. On a related matter, there seems to be a problem with the current build sometimes disregarding the Z minimum endstop on a home operation. (#17437) Configuration. You signed in with another tab or window. X0 Y0 Z0 at this point. EDIT: One thing to try that should rule out a homing sequence as a cause would be to set DISABLE_X or DISABLE_Y to true. #define SERVO_DEACTIVATION_DELAY 310, Thanks! https://github.com/thinkyhead/Marlin/tree/debug_G29. By clicking “Sign up for GitHub”, you agree to our terms of service and This is the homing sequence in Marlin. ... After homing the 3d printer again, the Z axis will be updated, and the -2.5 position will become the new zero position. Now that Marlin is configured, open Marlin.ino with Arduino IDE, choose Anet 1.0 board and corresponding port and press Upload. I agree that with all types of delta printers around, things get complicated, and i can see an option that looks for a delta flag somewhere to choose the order of things as the order used now ruins a lot of beds and nozzles as well on xyz printers without a heated bed. I updated on Saturday and have run a few test pieces, so far without any problems, thanks. In all cases of homing, always y homes first. Marlin’s extruders=0 or remapping of pins is used in the firmware to allow the use of all the control boards drivers. After detecting the home switch or home switch then index pulse (depending on configuation), and setting the coordinate of that point to HOME_OFFSET, LinuxCNC makes a move to HOME as the final step of the homing process.
