(CMD,jog4=2000)
(CMD,TrigThread 60.0)
f3600 g1 a0
M30

KMotionCNC is set up in the Trajectory Planner tab of the Tool Setup screen with Threading set to
Sensor Type 1: Encoder
Encoder Axis: 4
Update Time: 0.1
Motion Filter Time: 0.1
Counts/Rev: 2000

When I run the program, the spindle turns at the correct speed, the spindle speed display on the KMotionCNC screen shows 60 rpm, which is also correct.
But then the code appears to skip right over the TrigThread command and immediately moves the a-axis.

What have I got wrong?
Thanks

Hi David,

No that wouldn't work the Trigger Command would be sent before there is even data to execute. 

KMotionCNC supports GCode G32 to essentially do a Triggered/Synchronized G1 motion.

See the example:

ThreadingG32FrontV2.ngc

Also this video:

You should also configure the S command to control the speed.  Try to avoid using the comment CMD commands to  send Script directly to KFLOP.

Regards

TK

 

I'm trying to figure out the threading command and  have the following trivial gcode program:

(CMD,TrigThread 60.0)

KMotionCNC is set up in the Trajectory Planner tab of the Tool Setup screen with Threading set to
Sensor Type 1: Encoder
Encoder Axis: 4
Update Time: 0.1
