On one of the Mazak Nexus 250 machines i have with a barfeeder. When i need to change the chucking direction i first have to chane parameter R49 in the machine parameter section, change the chuck direction on the machine, then change the parameter back to what the value was. Have not needed to do this very often.
The problem i have is someone has changed this parameter and i now do not know what the value should be, and what i need to change it to, to change chuck direction. Anyone help please.
