My machine is set up at 1340mm/m but if i put it on 400% overwrite it dos not move as this guys video

Feed-override won't ever make rapid moves faster than the maximum in the INI file.

With the newer versions of LinuxCNC feed-override and rapid-overide are separate things, and are set by separate sliders in the GUIs.

The rapid moves happen at the rate set in the INI file, for example mine says:

[AXIS_Y]

MAX_VELOCITY = 45
MAX_ACCELERATION = 200

Which is 2700mm/min (45 x 60) and that is still not as fast as the one in the video.

What you could do is set the MAX_VELOCITY to 200 (or something else optimistic) then start the machine doing a loop of G0 X0 / G0 X200 with the feed-override or rapid-override set to 25% and slowly increase the over-ride speed until you get a following error.
Do this with a heavy workpiece but no tool.

Then set the INI file max to about 50% of the absolute max, to have a safety margin.

However, what that video really shows is very high axis acceleration and you might want to perform the same exercise on that setting too.

Are you using the original drives and motors? If you are, and if the analogue outputs limits are set to 10V then you should be getting the same torque as the original spec. Perhaps your Analogue out / PWM / PID max outputs are left in a "setup" state with low values?

Suggest that you might want MAX_VELOCITY of 333mm/sec/ That's a _lot_ more than you have at the moment.

Can you attach the HAL and INI files? That setup makes no sense at all.

f-error is _huge_

You have PID _and_ stepgen

The PID numbers look wrong.

Max velocity is 1,440 on a 20,000 machine.
