M-Series Operator’s Manual 4/9/15
Accept Mechanical Points in Digitizing Cycles
Default –Yes. Used when any given point has failed window checking # times where # = the limit as specified
in DSP Retry Limit. Setting this option to Yes records the last mechanical position rather than throw out the
point entirely. If this option is set to no, no value is recorded for the point and digitizing continues.
DSP Retry Dwell Time
Default – 0 seconds. The amount of time to dwell at the end of a retract move when retrying a DSP probing
move. The purpose of this is to give the probe time to stop vibrating before moving towards the surface again
on a bad hit.
Other DSP Probe settings
The DSP Probe eliminates the need for a multiple-hit probe measuring move (A fast inward move to find the
surface followed by a slow move to measure the surface). Therefore, the Slow Probing Rate (parameter 15) does
not apply to probing moves when the DSP probe is enabled. However, the Slow Probing Rate still applies to
TT1 tool measurements. The Fast Probing Rate (parameter 14) is still used for positioning moves in digitizing
cycles, but not for probing mvoes which measure the surface. Instead, the DSP Probing feedrate is used for
these moves.
The following list is a list of other parameters which affect the DSP Probe. See the parameter descriptions in the
Machine Parameters section (earlier in this chapter) for more information.
Probe Type (Parameter 155):
This parameter enables/disables the DSP Probe.
Recovery Distance (Parameter 13):
This parameter is used for failed DSP windows. On a failed window, the DSP probe will retract this distance
before retrying.
Fast Probing Rate (Parameter 14):
Used for positioning moves in digitizing and probing routines. These are moves which are not measuring a
surface. It is not used for surface measuring moves when the DSP probe is enabled.
Slow Probing Rate (Parameter 15):
Not used by the DSP probe. However, it will still be used by TT-1 tool measurements.
Repeatability Tolerance (Parameter 151):
Recommended value is 0 (disabled). This parameter enables repeatability checking. It will work in conjunction
with the DSP probe.
