Basic Information: Printer Model: SV01 MCU / Printerboard:SKR Mini E3 V2.0 klippy.log no log needed Fill out above information and in all cases attach your klippy.log file (use zip to compress it, if too big). Pasting your printer.cfg is not needed Be sure to check our “Knowledge Base” Catego…

I do have basic knowledge. I am an expert in marlin… not klipper. haha I am a klipper noob. I know klipper has to be spoon fed information to do the proper math and cant calculate like marlin can with only a few inputs. I noticed setting up offsets and such you get way different results with klipper…

If your endstop is at the back like all printers and your nozzle does not leave the bed then the position_endstop would actually be 0 and your min would also be 0. Then you would see how far forward your bed goes and that would be your max. Not the other way around. And yes front left is indeed the …

If your endstop is at the maximum position then it homes towards max and not 0. Endstop position can be beyond the maximum or minimum limits and can even be negative if the nozzle leaves the printable area. You may want to read here for this: [image] Understanding X and Y A…

I wont have a log until I fire this up for the first time but here is the section I was working on if that helps. [stepper_y] step_pin: PB10 dir_pin: !PB2 enable_pin: !PB11 microsteps: 16 rotation_distance: 40 full_steps_per_rotation: 200 endstop_pin: ^PC1 position_endstop: -14 position_mi…

[image] MILKMAN: Well the guide states that Y should home to the front when homing to the min position. Y should actually move to the rear for the min position towards the endstop. Unless it is some new printer that homes forward to a forward endstop which would be really weird. Unfortunately…

[image] MILKMAN: position_endstop: -14 position_min: -14 position_max: 265 If 0,0 is the front left corner as per standard and the position of your endstop is in the back then endstop_position can’t be below position_max. As requested by @Sineos please create a sketch with markings and pos…

[image] MILKMAN: SV01 Typically on such printers you will have something like: [stepper_x] position_endstop: 0 position_max: ... [stepper_y] position_endstop: 0 position_max: ... This means: Once you hit the endstop, you are at your 0/0 position your print-head is over the bed’s lower l…

Yes at 0,0 the nozzle is off the bed by 14mms. But I think I fixed it. I saw a klipper doc that states if you have over hang then you have to define the endstop and the position min the exact same. So i did that and now it homes dead center when I home it. I just tried it and seems to work. I just d…

Yeah I read that. hence the title of my post. That guide was incorrect stating that homing towards the min position that x goes left and the bed moves forward. I have never seen a printer home left and forward. I have always seen them go left and to the rear. If the bed moves toward you then there i…

[image] MILKMAN: If the bed moves toward you then there is a problem with your inversion. Everything is a matter of settings: My Trex goes forward for Y homing [stepper_y] step_pin: PF6 dir_pin: !PF7 enable_pin: !PF2 microsteps: 16 rotation_distance: 39.83 endstop_pin: ^!PJ0 position_endsto…
