Clean surface – Example values of a medium-sized machine:
Recommended settings guidelines for "speed":
Basic settings:
 Set high jerk values in traverse direction:
CfgLaPath: MP_maxPathJerk. You can nearly set rapid-traverse values for
the jerk.
Optional:
CfgLaAxis: MP_axPathJerk
(Software option 2 is required!)
=> a bigger following error s-diff is possible
 The triangle filter is recommended for tolerances > 50 µm (Cycle 32):
MP_shape = Triangle
 HSC filter is recommended at tolerances < 30 µm (Cycle 32)
MP_shape = HSC
 Define HSC mode (Cycle 32):
MP_hscMode = Roughing
 Set a high cutoff frequency:
MP_frequency = high value; recommendation: 50 Hz, if possible
 Set higher values for the transition jerk:
CfgLaAxis: MP_axTransJerk
You can nearly set rapid-traverse values.

Note
With the triangle filter and slightly increased jerk values, you can often
attain the same speed, but with a lower machine excitation than with HSC
filters.
