NT4250: TCP-mode (G43.4) with B-axis clamped/brake
The machine refuses to move in TCP-mode (G43.4) with B-axis clamped (M368) or brake clamp (M305). B-axis is kept at a constant angle the complete operation, only X,Y,Z,C moves, and doesn't have to be unclamped. Having B-axis unclamped results in heavy vibrations. Could it possibly be a parameter setting to allow this? Or any other suggestions?
I don't necessarily need to run G43.4, but not sure how the handle the combined X,Y,Z,C feed without it. Inverse time feed (G93) would have been a solution but unfortunately not possible in this machine..

Are you creating the code from CAM software? If so you might search for B axis moves while you are trying to clamp the axis. Just to make sure you don't have a B0.001 move hiding in there.
My DMG tech is here right now and we were talking about NTs yesterday. I asked him and he said if it was a parameter, it would be in the 19700 range. Not sure which one though.
