Homing and pure z motion is smooth but x/y is very jerky
Hi,
I am building a delta. I am using the atmega+ramps with external step drivers connected to the digital pins of the ramps board.
The homing and Z motion are very smooth, however the X/Y motion is very jerky and noisy.
I have tried different combination of jerk/acceleration/maximum feedrate/ segments per second ...
Any idea what can cause it?
I have also notised that setting feedrate multiplication to maximum (300%) on the host is redusing the effect.
Thanks,
Dima
