Configuring a Floating Head

I’m sorry if this is basic or in the wrong category. I have a floating head and switch set up, I also have the proma 150 thc. I planned on using plasmac config (I think that’s its name). I have not set up plasmac yet bc when I started to It suggest you have everything else ready. I have the z axis set to immediate home due to me not having a limit switch for home (I’m using limit switches as shared homes) and since I’m building a plasma cnc there are grates so it can’t always touch off to home.

So I need to configure the floating head without changing the immediate home.

Another issue I’m having. When the floating head switch is triggered then everything stops and it says “error joint 0 limit triggered” or something to that effect.

Linuxcnc 2.9, Mesa 7i96, proma 150 THC. These are my components

It may be joint 2 or 3, I don’t remember. Ok I’ll install plasmac then

i looked under plasmac and it seems to have recently been updated. Is this guide still correct?

You would be better off using V 2.8 which has just become the official release version of Linuxcnc and it includes Plasmac so the correct docs (for 2.8 are here)
linuxcnc.org/docs/2.8/html/

Follow the linkx to Plasmac from there.

Is there any way to downgrade without losing everything? I have most of the process completed

yes you can quite easilly. You need to follow the process on the buildbot page to install 2.8
buildbot.linuxcnc.org/

I just noticed that it still needs some revisions following the new release.

Maybe keep a copy of your working config just in case.

Two questions: Is it the same steps if I'm going form 2.9 to 2.8? The site talks about going from 2.7 to 2.8, but i dont see a mention of 2.9 to 2.8. second question: since ther are revisions happening should i wait to go to 2.8?

Actually I remembered that Phill had prepared a revision for the new release but they are still waiting for the docs to be updated.

Follow this link which also correctly covers 2.8 and 2.9
home.iprimus.com.au/phillcarter/buildbot/index.html

And yes the procedure is the same. Set the deb and deb-src to the correct version and follow the instructions to change.

Version 2.8 is now stable and will only change if bugs are found these should be bundled into a V 2.8.1 release.
