I am in the process of replacing my MK2 controller with and MK3/4 and TNG. Have not fired it up yet.

But trying to translate the old settings to the new ones I noticed pretty much all the old lookahead settings are gone and instead there is the "join/break angle" on the "blend" tab. For a regular mid-size 3/4-axis router should I just leave the 0 degree/135 degree values alone? And is the 1.5mm XYZ and ABC blend tolerance O.K.? I used to have a lookahead angle of 172 degrees and lookahead radius of 1mm with 200 mm/s^2 radial acceleration to avoid lost steps. Not sure if that was the optimal settings but it worked.

Thanks, JB
