M-Series Operator’s Manual 4/9/15
Smoothing Configuration Parameters
Parameter
Description Recommended values
220 Turn the Smoothing feature ON or OFF . 1 = Smoothing (set to 0 to use Exact
Stop mode)
221 NBpts: The number of points in the Smoothing filter. The
higher this value, the more rounded corners will become (see
tolerance below)
For Milling
Machines:
0 to 10
For Routers:
5 to 20
222 STEP: Smoothing breaks up a G code program into segments
of this vector size. Use this rule of thumb: Tolerance =
(Nbpts*STEP)/3.
For Milling
Machines:
.001 inch /
.025mm
For Routers:
.01 inch / .25mm
223 Umax: Sustained safe throughput rate going to the
CPU10/MPU11 card.
800
224 Centripetal control options: This bitfield parameter controls
the Centripetal stage of the Smoothing module.
Value 0 (default) makes Centripetal operate on all axes and
disables excessive axis accel checking.
Values 1 and 3 (bit 0 = 1) limits Centripetal to only linear axes.
Values 2 and 3 (bit 1 = 1) enables excessive axis accel checking
0
(Centripetal stage will operate on all
axes and disables excessive axis accel
checking.)
226 W: Feature Width over which the Min Angle is determined. 10
227 Min_Angle: Minimum angle to smooth in degrees.
Settings of 95 to 100 degrees will come to a near stop and
produce sharp right angles. 60 to 85 will move continuously
while rounding angles.
For Sharp
corners
95 to 100
degrees
For rounded corners
60 to 85 degrees
228 S curve: The recommended setting for this parameter is 0. 0 = Off completely (recommended
setting)
229 Backplot/Smoothing mode : Smoothing may slow down the
display of Backplot Graphics. This parameter allows a faster
backplot by not showing Smoothing.
0 = Faster Backplot, smoothing may be
active but is not shown
1 = Slower Backplot, smoothing effects
shown.
230 Curve Feedrate Multiplier: Reducing this value below 1.0
will cause the machine to move slower around curves and
corners, minimizing "bangs" and overshoots. Increasing this
value above 1.0 may allow you to run your machine faster if
the feedrates in arcs and corners are still satisfactory.
1.0 (default value)
0.1 to 5.0 (Depending on user's
preference for speed vs "bangs" and
overshoots)
231
Acceleration Multiplier: This parameter allows you to
adjust the overall acceleration / deceleration rate as a
means to reduce machine vibration, and noise during
starting, stopping and feedrate changes. Reducing this
value below 1.0 will cause more gentle accelerations and
decelerations. Increasing this value above 1.0 will cause
faster accelerations / decelerations.
1.0 (default value)
0.5 to 1.5 (Depending on user's
preference for quickness of
accelerations / decelerations)
