Hi all,

I came across an odd problem with my machine today. When I'm both running some Gcode or jogging, the steppers sound a bit dodgy and it causes the whole machine to vibrate and make a high pitch almost frictiony sound. However as soon as I rotate the toolpath it stops and the steppers and machine sound very smooth and happy again.

Has anyone got any ideas on what could be causing this?

(Also this happens at whatever maximum speed I set for the motors in motor tuning)

Thanks,
Andy

Machine details:
2.2Nm Nema23 steppers. Drivers set to 5 mircosteps
Running Mach3 on
Windows XP, Intel Pentium 3Ghz, 2GB RAM
