what version? does it also happen with |
|
I have changed boards to a skr1.3 (to remove that variable) and (had fun getting) bugfix-2.0.x branch installed. I have included the gcode I have used to reload the mesh. After zeroing all the axis, I then move the Y axis and at just over 900 and I get the z stepping up. |
|
So I changed my bed size from I loaded the same mesh data (to pretend the machine was smaller but with the same mesh data) and the machine does not setup up on the z axis whilst moving the Y axis. |

@wrightwells, I plan to put some effort into debugging reported leveling issues over the coming weeks. I'm sorry to ask you to do it again, but without hardware similar to yours it would be hard for me to know if it is still happening. Please include your configuration files and any other files you may have modified, such as your board's pins file. |

@sjasonsmith Will do and thanks, I'll attempt to do this at the weekend. |

Marlin-bugfix-2.0.x (18112020) marlin config.zip So I tested it again and moving the y axis between 810-820 causes the z to lift and drop. This time I did not zero the axis, I just rebooted and moved the y axis. Thanks |

I'm having similar quirks with 2.0.8.1 and a bed of 200x995mm when using mesh bed leveling through G29 S1 and S2. Halfway the nozze starts using different curves to move from point to point, and the last 5 points (of 25) fail completely: Log OutputCould it be some kind of overflow, like Repetier describes? |

Keep open |

To help with diagnosis, first be sure to download the current Then, get your mesh set up so that you'll definitely get weird behavior. Move the nozzle to a position where things are okay and send |

Bug Description
On a large bed 2400mm x 1220mm after running a manual bed leveling the Z hight jumps 5mm at approximatly three quarters along the Y axis when moving along the Y axis either via the controller of within gcode.
However it transitions smoothly betweem points when a simple mesh is entered with a greater height difference between points.
My Configurations
I have a RAMPS1.4 and have uncommented the manual mesh bed leveling and set it to a grid of 4x4
Configuration_adv.zip
Steps to Reproduce
6 Move X axis 50
Expected behavior: Smooth transition between mesh points
Actual behavior:
Makes a rapid 5mm+ movement at all points along X axis between Y point 700 - 900 whilst moving along the Y axis.
However using test grid A (above) the transition is smooth.
Additional Information
Video showing jump in Z
video error mp4.zip
Actual mesh that cuases the issue
Test mesh A that raises along the Y axis
Test mesh B that raises across the X axix
