    Cutting thread on CNC lathe by Mach3 ?

    Would you please help me out cutting thread on CNC lathe by Mach?
    I couldn't use the Wizard. It keeps stopping at line G76.
    I have a rod aluminum 28.5 mm main core and want to cut 3mm pitch to 25.5mm, distance 20mm. My spindle is 62RPM. How would you program this? How do you calculate feed rate? Please help and thank in advance for your help.

    thank you in advance for your helps

    Mach is stalling because it is waiting for a spindle speed impulse?
