Thanks for the reply.
I tried DRO 829, but it stays unchanged at 0. It shows up in the Brains editor, but it's not identified in the MachScreen editor. I tried writing a Brain. I can get the Jog % value, but I don't know how to access the number to multiply it by. It appears to be the maximum Velocity from the motor tuning of whatever axis I'm jogging. Any suggestions?
This number would be very helpful when using my pendant to do a Constant Velocity move. I can look at IPM and tell if the cutting speed looks OK, but I don't have a feel for percentages!
