Unexpected realtime delay and genserkins

I have problem when command G0 is running
There is no errror when homing

Dummy config brings nothing

What version of LinuxCNC and how did you install LinuxCNC?

Also can you get those numbers I mentioned before and after the first G0?

An easy way to get the max times of all functions is this:

halcmd show param *.tmax

Coming late to this...

Note that tmax is in clocks, not nS.

Perhaps genserkins itself is getting stuck in an iteration loop and taking too long to compute a result?

I think its possible

How can check it?

There should be a genserkins.tmax HAL param.

There is not pin "genserkins.tmax"

Ah, sorry. It's not a HAL module is it?

Genserkins runs as part of motion. (and you have already looked at motion.tmax)

It might be instructive to halscope the motion function period to see if it jumps near the troublesome position.

It looks like Genserkins hasn't changed for quite a long time:
github.com/LinuxCNC/linuxcnc/commits/mas...ematics/genserkins.c

What are you actually controlling? I wonder if Pumakins might work?

I need to control arm with serial joints. Pumakins is not valid for me.

Can you please post the results of this:

halcmd show param *.tmax

After homing:

Owner Type Dir Value Name
28 s32 RW 0 hm2_7i92.0.read-request.tmax
28 s32 RW 629562 hm2_7i92.0.read.tmax

21 s32 RW 122232 motion-controller.tmax
22 s32 RW 768200 servo-thread.tmax

When G0 command starts and error appears:
