Eliminating Cutoff deceleration on Mazatrol

[Crashmaster]

I just got a new quickturn nexus lathe with mazatrol. There has to be a parameter that lets me eliminate the deceleration on the cutoff (grooving) toolpath as the tool approaches X0. From the parameter lists it seems parameter TC50 should control this but changing the value doesn't seem to affect the feed/speed. Any suggestions?

Nevermind guys, I got it figured out. Parameter TC49 did the trick.

you can do lots of cool stuff with #4 and #5 cut off cycles. built in parts catcher up. chip breaking, distance beyond center, slowing down feedrate at end of cut, going from css to direct rpm, to not shot the part, but let it fall into the catcher. slowing down fr through out the cut proportionally.

takes some time to perform all the parameter, program value changing experiments, but, theres lots of coolness and capability to it most people dont even realize is there.

to put it another way, i know there's enough there to realize there's possibilities, but i didn't ever conduct enough experiments to master all of them. and if i can hardly understand it all, it's then impossible to explain!
