Like I said, try feeding the motion adaptive feed with lincurve

Sorry... I have now idea how to do that... I think I will leave it this way, it's not that important. Thank you all for your good answers!

I can't imagine using LinuxCNC without learning how to use hal. Lincurve is a component:
linuxcnc.org/docs/html/man/man9/lincurve.9.html

So is motion. Motion is where all of your axis and spindle stuff is controlled:
linuxcnc.org/docs/html/man/man9/motion.9.html

You need to understand how pins and signals work. If you want more help post your hal file.

I'm learning a lot about linuxcnc/hal/linux/mesa/steppers/servo's/spindles/metal/wood/etc, etc. But first things first... I didn't even make my first chips/dust.
It's all very very very interesting, but I have to make choices... :-)

Lower the velocity, start using the machine, it is much better to have a really slow machine till you get used to it, then you can decide if you actually need more speed, and if you do, there is plenty of help here.
At first it all seems unreasonably complicated, but keep reading and doing, it all clicks after a while, and Blazini's advice will make a lot of sense when you get to know what HAL can do and how versatile it is, it opens a whole world of possibilities to make your machine (whatever machine) do exactly what you want it to do.
