It may be better if you post a drawing of what the slot should look like as the code is creating arcs from line segments for some reason, you should only have about 15 lines of g-code to produce 2 slots with rads in the corners.

you can not have a G02 or G03 with a radius of zero, if you tell Mach3 your tool is 2,999mm it will work.

Go into config and change the Abs/Inc setting on the arcs

I find it strange that a CAM program can not substitute M30 with an M0 and a M47 or add them on the lines before the M30, it sounds as if you need a new CAM system to me.

why not just loop the g-code put something like this :-

G00 X0 Y0 Z25.
G01 X.....
...
(BODY OF CODE)
...
M0 (WAIT FOR CYCLE START)
M47( LOOP)

Or you could use the dangerous method, NOT RECOMMENDED!

G00 X0 Y0 Z25.
G01 X.....
...
(BODY OF CODE)
...
G4 P5000 (WAIT FOR 5 SECONDS)
M47( LOOP)

Start by setting your steps/per and a modest velocity,  there are no real starting figures as every setup is different, I would start with the latest autotune and see how it gets on.

http://www.cs-lab.eu/en/artykul-4-Download.html

Set the axis in the middle of the travel and press the autotune button, the axis will move + and - many times until it finds an optimum setting,  You may need to hit reset and re-run it if it faults.

As a guide my settings for the X & Y axis on my small mill are 16384, 200, 1000,500 and Z is  77000, 87, 1000, 1, but they may be of no use at all on your machine.

you could do a while isactive() loop and check any input, if you have a servo spindle you could do swapaxis(x,y) and do a home command to find the signal.

It sounds like you have the acceleration set too high try lowering the values in the motor tuning and work back up to find the optimum point.
