Thanks. It works now.

However I have spindle.0 and spindle.1 and as soon as I added spindle.1, spindle0 stopped working (Linuxcnc - Qtdragon only sends the setpoint.0 value and no enable signal). Strange.
 

Upload your config ... I can check it.. more detail as ..

Thanks for a help, I am not big pro in Linuxcnc. 

Spindle.0 is Delta C2000 and ethercat card running in Velocity mode. So I made comp file that sending enable signal to it and the rest is usuall cia402.

Spindle.1 is SD2S via CoE. 

If I have just one spindle.0 its running well. Then if I add spindle.1 it runs well but spindle.0 receive just setpoint without enable word.

okay ... thats kind weird ..

it should not runs like you described ...

maybe help convert setpoint to bool and there will be signal enable ... or use some general enable to enable spindle.0 too
