Hello everyone,
according to linuxcnc.org/docs/2.8/html/plasma/plasmac-user-guide.html

It is possible to increase this speed by up to a factor of 10 by adding the following line to your <machine_name>_connections.hal file:

setp plasmac.probe-final-speed n


gives this error

twopass:found ./plasma_connections.hal
twopass: Error in file ./plasma_connections.hal:
setting parameter 'plasmac.probe-final-speed' to '5'
parameter or pin 'plasmac.probe-final-speed' not found


any suggestions?

machine is working and cutting with no errors

Best Ben

Believe it should be:

Warning: Spoiler!


I am working on proof reading/updating the user guide. I will make sure to note the change. Thanks for pointing it out!

EDIT: Actually plasmac.probe-final-speed should be correct... What version of PlasmaC are you on? This was a feature that was recently added, and if you are before v0.170, that is the problem.

How did you install LinuxCNC?
If it is a buildbot install, in aterminal:
sudo apt-get update
sudo apt-get dist-upgrade

That is only the last major update, if you look at the bottom of the config panel next to the buttons it should show the version.

After update (with no hassle) works like charm, Thanks for the help :)

i have the probe up speed at 10, is there a way to bump that up even further and can someone guide me in the right direction e,g. docs, was thinking on percentage of probe down speed or, probably easier to implement keeping the factor but making it faster

Best

Line 787 here:
github.com/LinuxCNC/linuxcnc/blob/master...ponents/plasmac.comp

I was reluctant to take it much higher in case it affects the probed height too much.

Thanks again for implementing the feature Phill.

I was in agony because of this, having an immensely fast machine waiting for so long.... :)
