Guess I am lost by how you are getting the 96G's
115200ipm = 160fps = 4.973g from my convert program.
Help out an ole toolmaker. LOL

No doubt, Send us a video clip on first test. LOL

Assuming my math is correct:

         80   f/sec   =   960   in/sec
         5000   rpm   =   83.33333333   rev per sec
                     
Assuming a   4   in dia pulley   12.5664   inch circumference         

         1047.2   in/sec         
         87.26666667   ft/sec         
-------------------------------------------------------------------------------------
         80   f/sec   =   960   in/sec
         7500   rpm   =   125   rev per sec
                     
Assuming a   2.5   in dia pulley   7.854   inch circumference         

         981.75   in/sec         
         81.8125   ft/sec         
      
Good Luck

80feet per second = 960inches * 60 seconds = 57600 inches per minute
80 feet/sec = 4800 feet/minute * 12 inches per foot = 57600
54.54 mph

80 feet /sec = 2.49 G

Based on my Convert Program

I'd use one of these to do what you want.

You can write a program and download it to the unit.

Self contained just need a Power Supply and a means to trigger input the program to start and stop. One trigger to send it home, trigger to start, trigger to stop and what ever you can think of. You can change/set the accel/decel and speed during the program run. You just write a text program and then send it to the processor. Different programs can be run depending on the trigger that is sensed. Great for repeated routines. Fun units to work with too. But Servos are so much faster and more powerful, Parker makes a GV Drive that does this also to control Servos that I have used.

Your X-axis drive velocity settings would have to be three times the velocity set for Y.

Does make me wonder what the acceleration ratings would need to be set to keep them in sync.

/m99 p100 (Fanuc control It would jump to line number never tried it in mach3)
M99 (repeat the cycle)
M99 p1 (or might try that to go back to the beginning of the program, again not sure about mach3 use of m99's within a program)
N100 G0 Z0
X0 Y0 M5
M30

I create as many as I would need to skip sections of the program. Example: I use it to finish out an endless loading routine on a lathe. When I need to complete the cycle it would jump to a section of code that would clear out the loading sequence and end the repeated cycle of loading and then machining. Finishes the machining of parts and then puts the machine, gantry and palletizer  in the home position for the next day.

The / block delete is an ignore.

Think you meant Mach4, and I am sure they will, just not sure we all will. LOL
