After seeing how much smoother overall as well as how much faster rapids and acceleration can be achieved via another controller I can't believe Mach3 does not have a setting for jerk, I hear it is basically infinite.
Best reliable settings testing jogging on the same machine:
Mach3 + Kflop Motion Control Board: 200ipm rapids and 5in/2^2
KMotionCNC + Kflop Motion Control Board : 300ipm rapids and 10in/s^2
I also have been having issues where I think the acceleration limits set by Mach3 are being ignored possibly related to CV mode resulting in my drives faulting out due to over acceleration. During searching for solutions I came across numerous issues with CV mode which I am guessing are compounded by not being able to tune down jerk. Please, please, please, implement a setting for jerk.
Thanks,
Adam

No development of mach3 has taken place for years with regards to the internal programming and update releases, I would not get your hopes up too much as all development is being put into mach4 which is having a slow birth as far as offering all the same functionality as mach3 (turn, plasma) improved with speed, interface and code (lua)

Yeah.. Totally... The TrajectoryPlanner needs to be improved. There are deceleration violations. If only Brian and Art were working together still... they lost interest; The market changed. I have to say at this point in time... either go to Linux cnc which has a nice TP now.. Which is a pain in the arse too... Linux is too much trouble to learn if you come from zero knowledge .. and supporting it also is much harder.... Just try to find a computer that will install linux in a hurry... try to run all your programs in linux... good luck.
I still didn't give up in mach4.. I am constantly checking the development.. and asking Brian... and getting not many answers.
One thing is for sure... give mach4 a good TP and good mill functionality... I will hang on to PCs for ever.. they are fun.
