Where are the results of the latency test stored?

Hi all,

I've customized my .ini and .hal files quite a lot, and I've just setup a new computer for the old machine which has a different latency score. As I cannot run StepConfig any longer, how/where should this new latency result be updated to the new system?

Thanks for any help.

Cheers!

The latency test results are not stored in any configuration file, but what
stepconf can do is choose a base thread period based on you latency test results
(it chooses a period that's twice your base thread jitter figure)

You can set the base period directly in your hal or ini file

Thanks.

Is it here in the .ini file? I'm guessing that I could create a new step configuration and just copy this section to the old config?

[EMCMOT]
EMCMOT = motmod
COMM_TIMEOUT = 1.0
COMM_WAIT = 0.010
BASE_PERIOD = 100000
SERVO_PERIOD = 1000000

You said it can be set in the ini or hal file. Where is it in the hal, and what takes precedence?

Cheers!

BASE_PERIOD = 100000

Is the statement that sets base thread period in the ini file

If your new mother board has different latency, you can adjust this number to suit

if you set the base thread period too short, you will get real-time errors and may make your machine very sluggish
If you set the base thread period longer than needed you will limit your maximum step rate = maximum axis velocity
