Geeetech

Hello Geeetech Forum, until this morning, the A30 has printed super. Since today the middle position is no longer in the middle of the heating bed. It is about 5 cm away from the middle of the area. When I start printing, the printhead moves to the wrong position and starts the AutoLeveling, but always 5 cm further back than "normal", so that the last row of the 9 leveling points is only 1 cm from the edge. This creates incorrect readings and results in a wrong non-clean print image. How can I reset the middle? I have already reset the factory settings and renewed the firmware, both without result.

It seems your printer lost the hardware version.
Then the firmware can't work normally.
You can send this gcode via Smartto toolkit:
"M2009 V3.0"

Hi William,

thanks for your help. The HW Version is now shown in the "About Screen". But the y Axis is still in wrong place. If i press the "Home" sign the A30 goes to the Coordinates given in the picture. Is there a Command to set the x and y axis to 160? That should be the right place.


Thx for your help

Hi again Forum...

How can i adjust the x and y Home Point? See picture above... Pls help me...

Hi friends,

I just found that when I do manual leveling, the starting point is at x0y0. OK. If I turn on AutoLeveling then the home point is at x162y211. with the result that the AutoLevel starts at the wrong point. Normally it starts in the Point x169y160. I think there is something wrong with the AutoLevel calibrated.

It is correct. When it homing then it will stop at X162 Y211.(The Z values of mine is the Z2)
We didn't see the problem with it.
When it starts print then it will move to the correct XYZ point.

Ok, with Hardware Version 3.3 my Point is same like yours.

Thank You very much...
