Good day
I am having a problem with "erratic cutting"..i.e. if you cut a square shape using a "multipass cut"..the first pass "sort of" cuts fine then the second and third cut start "moving/cutting" to the right handside of the first cut so you end up with 3 cuts in different places( asuming you selected a 3 pass cut)..
I said "sort of" cuts fine because the shape is recognisable, but, on cutting the x-axis it seems the x-axis movement is "jerky" in places.

I have run the motors from side to side and forward backward using Mach3 and keyboard keys...the movement is fine...so it seems like a Mach3 setup requirement.

Can anyone assist...or preferably is there a "standard" setup on Mach3 available for a 6040 using Nema stepper drive motors.
