Can anybody assist, I upgraded from mach ver1.84 which was working perfectly on my lathe, to ver 3.042 now the spindle will not control above 600 RPM it just ramps to full speed, axis run with an intermittent motion ramping from slow to set speed and back. The driver diagnostics appear normal, the computer is a PIII 531 MHz with 256M ram running windows XP Pro the kernel speed is unchanged at 25000Hz.
Brian.
