The title pretty much says it all .
TSR program runs but when it runs a subprogram (for homing movement) 73ff comes up . Not much in the manual about it and this is the second time I got this error, and it is persistent . Powering of does not help .
Re-uploading and restarting the project did the trick last time but I'd like to know how to avoid this issue in the future .
Any help is welcome .
Regards
Nikolai
