Y axi is opposite

Hi I try to use laserWeb with 3d printer with laser head addon. I noticed that y axis is oposite: When homeing the laser headset comes to the right position (0,0) but showed on softwar as (0,230). Also the direction button of y movement is different. When I move this axi using gcode/cura it moves to right direction. What should I do?

Thanks

Where is your homing location relative to the bed? (top/left, top/right, bottom/left, bottom/right)? Does the head or the bed make the y movement?

Which firmware is being used? How does it work with the 3D printing software? Assuming your 3D printer works for 3D printing tasks, I'm not clear why Y axis would be backward with Laserweb. In Smoothieware, you can set homing position, see [(https://smoothieware.org/configuration-options)] with variables beta_homing_direction, beta_min and beta_max

But what is strange is homing works, so it makes me believe the Y axis connections between the controller and stepper driver are ok? Unless both homing position and Y direction signals are swapped.

Also, careful with position being shown in Laserweb. These are workpiece coordinates, not machine coordinates.

buttom left (if I look from top view) but in the app is shows as top left

I use marlin, and when I use the screen to move the axis everything is fine, I'm familiar with 3d printing and I'm sure that it's ok in this matter. I see that the beam looks like it's from button and not top in the app so I think that something is wrong there, like it's mirrored somehow

LaserWeb shows the head at 0,230, because that's what your printer is reporting in the position messages after homing. So it seems that a work offset of 0,-230 is stored in your firmware.

Just click on the "set zero" button. That tells the firmware, that the actual position should be 0,0 (in work coordinate system).
