Yes I do indeed, just to clear confusion in case there is any, the steps per and speed of the motor in mach3 is all setup correctly and I was able to reach the speeds by increasing my motion controller frequency which gives me the option to. so there is no software/hardware limit that prevents me from entering a larger speed and acceleration if I wish, the problem occurs by having the motor stall after a little jogging.

but if you mean that there is an inherited limit in using a 5mm pitch screw that I can't go past for example 7m/min can you please let me know if such is the case?
