6 axis UVW do not move (1 reply)

Hi, guys.

I have a problem trying to put 6 axis to work on MKS Monster 8 board. Basically I configured the LINEAR_AXES, axis letters, all kinds of max speeds, jerks etc. The result is that marlin seems to know that it has 6 axis, but it does not move them.

Here is some communication between me and Marlin.

So you can see, that it received the command, and understands that it should move to X1000 U100, but moves only X axis. What can be the problem?

Best regards,
