Hi guys,

Thanks for the responses, I have taken the advice and changed the microsteps to 800m/s on the driver card, this is using dipswitches 5,7 and 8 ON. This has made the axis much quicker but still very jerky and growly.

The kit im using is actually chain driven, heres the link

This means im struggling with the steps per value, as there is no leadscrew to figure out the calcs.

For some reason I can't attach a screenshot of my motor tuning, but its set to

steps per = 200
velocity = 3000 mm/min
accelration = 16.66mm/min

step pulse = 0
dir pulse = 0

Still very noisy and jerky.

Appreciate all the help

Thanks
