Andy brought up this in another post, and I didn't want to hijack that
thread.
I wonder if screwmapping of one axis could be applied to another axis.
Here's the scenario:
Long X axis on my CNC saw beveler. At this point, I'm unable to get the X
bed much flatter than + or - .006, and it varies

IMHO something like that might be done with a small compensation

You could populate a lincurve component with the required Z offset
for each X. Then link the lincurve X axis input to the axis position
pin.
Then use an offset component on your Z position driven from the
output of the lincurve.

I you have multiple cores 4 or 8 (but you shouldn't) there is a different
isolcpus setting to optimize the RTAI results (aka latency).

When you switch to a new version of the RTAI kernel you should re-run
the latency test. The new kernel usually works better

Hi Sebastian .
Is the base thread period adjustable for the latency test gui ?
If yes , can you please tell me how can I do this ?

You don't need to set a base period to run the latency test. Just run
it, and it'll measure the latency, and you use that to pick a

Thank you Sebastian .
If your base period is too fast for the new version of RTAI on your
hardware, you may experience the kind of lockup that you describe. In
this situation you'll have to increase your base period or revert to the
older kernel.
I misunderstood you comment . :-)
