[image] Sineos: position_min must always be equal or less (more negative) than your position_endstop. If you set position_endstop to -10 then position_min must be -10 or more negative, e.g. -10.1, -11 etc

Hello @verce3d ! If the homing position is out of the printable area, try with negative values for the [position_endstop]. Like this for X and Y: position_endstop: -10 position_min: 0 Besides this, please note: [image] Creality Sonic Pad and Alternatives Knowledge Base …

[image] verce3d: Ender 3 V2 Neo This printer has an effective build volume of 220 x 220 mm. This means you need to enter this size in your slicer and not the max of 235 x 230

Thanks for the replay, I will try that. I understand its not real klipper, I said that on the post. But due to the severe lack of customer support from creality on the subject you guys are my best bet to get any orientation on how to solve my issue. I understand the basics of programming so any help…

Thanks, the printing area in the slicer is 210x220 that’s the actual working area of the bed. there’s 10mm lost to the “sides” in the X axis that’s not printable unfortunately. I had tot use the 235x230 on the config because it wasn’t using the full Y axis in the bed when the sonic pad flashed the f…

Just to give an update to the post, the solution of changing the position_endstop: -10 didn’t work, keeps saying "Unable to infer homing_positive_dir in section ‘stepper_x’ goes the same for the y axis. should I use the homing_positive_dir true or false to maybe get this working? saying the homing…

The problem is not on the max position but on the 0,0. If I input 220x220 lets say to use the “whole” bed, the bedmesh has to be rebuild in positions and they won’t get the right places anyway, since the 0,0 is way off the bed. This is in part because the sprite pro on the ender 3v2 Neo needs a diff…

Klipper does not know your bed or which part is usable. Let’s take the following situation, where the red marked area isn’t usable: [image] In this case, you would set for the Y stepper: position_min: -20 position_max: 180 position_endstop: -20 Now your Y=0 (from the slicer perspective) will …

Sineos thanks for the fast reply, the issue I’m having is that when trying to set the position_endstop to a negative number or the position min, it gives me the unable to infer homing_positive_dir warning, so I was wondering if I have to specify in the config which direction is positive using the ho…

position_min must always be equal or less (more negative) than your position_endstop.

I understand that, when I tried endstop -10 position min 0 the message was still there after saving the mods. I will try something else I guess
