After you have homed the x axis and you move with the middle of the nozzle to the left side of the bed what is your motor position? Normally it must be 0. if not you must adjust your x minus in your printer.cfg. If you hit with your Toolhead the motor mount and your theoretical 0 is in the right side of the left side of your bed you must move with the motormount more to the left.

You must adjust this value. In my case it mean if I hit the Endstop my x position is-3mm. So I must move +3mm to the right that my nozzle is in the 0 position of the bed.

That is clear. But what is your motor position after you are homing and move your nozzle to the 0 of the bed

Did you have space between Toolhead and were you hit the motormount
national-goldOP•2y ago
no the fan duct did hit the motor mount
sunny-green•2y ago
So you must move the motormount to the left.

how much xD

The length what you need to come with the nozzle to 0 of the bed. I would say in you’re case 5mm or so. You are in front of the printer. Measure what you need and move the motormount. Loose the belt. Maybe you need a longer belt. But first try it
position_min: -5
endstop_position: -5
this means 5mm to the left
try it out and retune it, its easy

He hits the motor mount with the fan duct in this position during the homing.
please show the end of the gantry / rail?
maybe the whole gantry is on the wrong location
you bump into the motor mount, but this should happen 1cm to the left of the bed

move your motor mount closer to the spindelblock
the gap is too wide

check your gantry position and the rail position

it should be flush to the z spindleblock

or 1 cm
read the documentation, its all there
even with images
national-goldOP•2y ago

A little gap to the backlash nut that you can adjust this later is okay.
national-goldOP•2y ago

Take a look on the picture what Helge had send you and what you have build.

Now it’s okay. Maybe if you want and your z axis is straight in line so that you don’t need to adjust the z axis you can move 3-4 mm with the motor mount to the anti backlash but. But I would say so it’s okay.
For your case please check the 2 positions that Helge and I say to you yesterday. Set this to 0. position_min: 0
endstop_position: 0
