 .SH DESCRIPTION
 By default, the base thread does not support floating point.  Software stepping, software encoder counting, and software pwm do not use floating point.  \fBbase_thread_fp\fR can be used to enable floating point in the base thread (for example for brushless DC motor control).

 The \fBnum_joints\fR parameter is conventionally set using the INI file
 setting \fB[KINS]JOINTS=\fRvalue.  The \fBnum_extrajoints\fR is set by
 the additional motmod parameter \fB[EMCMOT]motmod num_extrajoints=\fRvalue.

+HAL pin numbering for all joints is zero based [\fB0 ... num_joints-1\fR].
 When specified, 'extra' joints are assigned the last \fBnum_extrajoints\fR
