Hello,

I am a newbie on this forum !

We have a brand new Multus B300w machine on our floor. We are able to preform the sequence restart on the main spindle without any problems. But when we try to preform the restart on the subspindle the machine errors out with error "1741-20 chuck unclamp spindle 1".

We have tried everything from closing the main spindle chuck with the foot pedal to programing in an additional command to close the chuck.


I know it must be a simple g or m code that is missing from the program.


Thanks in advance,

Robert
