Left heatbed screw touches aluminium frame

I noticed this problem , when I had trouble manually pushing the heatbed back , from the front of the printer.

The M10 threaded rods are fully seated in the aluminium frame , so I have no Idea what is the problem .

I fixed this . The problem was that the Y-axis corners were not the same height , which caused the bed to be uneven

Hi Emils,

if you place the printer on a flat surface, does the frame have same distance on both sides from the surface?

Is the screw fully tightened?

Can you please take a picture from the back of the printer at the time the screw on the Y-carriage is hitting the frame? and once more please ensure about following:

1) Black threaded rods are fully and equally seated in the Z-axis frame

2) All heated screws are fully tightened (be careful with the torque)

3) The smooth rods are fully seated in the Y-corners

4) The Y-carriage is levelled (horizontal)

Hi Emils,

can you please do following?

1) Check the Y-axis frame isn't warped (use flat surface)

2) Slightly lift the affected side up.

----------------

If it doesn't help then:

3) Measure the dimensions of the aluminium frame in the area where the screw is hitting it. I will compare it with another frame.

4) Take down the heatbed and with level ensure the Y-carriage isn't warped?

Thanks

1.I checked the Y axis on a flat surface and it was straight , not warped , and I also checked the heatbed if it was bent , but it wasnt.

2.I tried lifting the affected side up , and it was barely high enough , for it to not touch the aluminium frame . I then tried to calibrate XYZ and when the nozzle went to position 7 and 8 , it started dragging the paper , but it didnt drag the paper on the side , where the screw touches the aluminium frame .

The aluminium frame , in the place where it touches the screw , is 48.20 mm

The Y carriage is not warped
