axis problem
-
I have a problem with my CoreXY 3D printer – it moves in both X and Y direction even I only ask for movement in one of the directions.
When I ask for a movement of X or Y it does so in both the X and Y direction – this means that it only will move diagonally.
I am able to make it move in one axis direction using G1 H2 X / Y specified mm; but it still moves diagonally when I press “Home” on X and Y so that does not solve the problem.
I hope one of you are able to help me with a solution – so it only moves in the direction I specify.

@Bak post response to M115 for firmware version, and your config.g, please.

@Bak need to see FULL config. If that is your full config, you haven’t told the firmware that it’s a CoreXY with M669 K1.
If that is in, see https://duet3d.dozuki.com/Wiki/Test_axes_or_motors_individually and https://duet3d.dozuki.com/Wiki/ConfiguringRepRapFirmwareCoreXYPrinter

and thats the config.g from your printer? not one that you have saved locally?
please post the output of M669

No it's from config.g on my printer

Post your homeall

@Bak said in axis problem:
move in one axis direction using G1 H2 X / Y specified mm;
Are you sure you have a CoreXY and not a Cartesian printer? Can you make a picture of XY steppers and belt construction please?

That's not a corexy machine, that's a Cartesian with an ultimaker style gantry.

Thanks. I'm reasonably new to this and thought I knew the difference between CoreXY and a Cartesian printer.
Thank you very much for your help I have fixed it now so it runs as it should
