At a later stage, I plan to add an additional 1kW servo motor, which will operate in torque mode to act as a dynamic load on the main 7kW motor. This will increase the system's rigidity. Currently, I'm using the encoder from the main motor
 

That sounds interesting.  How are you planning to couple the secondary motor to the spindle?

Are you sure the proximity switches are deactivated (red in halshow) when not at home position?

If these were inverted, the "home" move might actually be LinuxCNC backing off what it thinks is
a closed switch.

Kept looking last night and ran the IRQ script found else where on this forum.
This seemed to improve things, I left LCNC running all night with glxgears and other things running and did not get the messages again.

The issue maybe be fixed I'll see how we go actually using it today.

1. make sure both Y spin in the correct direction
2. what sensing distance do the proximity switches have? 1 and 2mm should be avoided. And switches are not mounted correctly, they should be sideways to prevent crashing into stuff.
For 1:
make a normal 3 axis test config, test one Y with a short jog, change drive inputs and test second Y with a short jog.
This can be done on software but more complicated to explain.
