I have been holding off asking questions on here because I figured I should be able to muddle my way through it. Well I got everything installed and everything seems to have worked. Also it seems that zero stray cats where installed which in guessing is good lol. But I have come to a point where I'm kinda embarrassed to ask for help. How do I run this new fangled thing-a-ma-bob? In the home/user folder I have a folder that says LinuxCNC and LinuxCNC-dev. I'm guessing the LinuxCNC is from my previous install. I dug around the dev folder buck can't see anything to run. If I open a comand prompt and type LinuxCNC it looks like my standard cnc that opens. I dig around in the samples listed and can't find anything named like the screen shots posted on the first posts by the OP. Thanks guys - JT

My plasma table is on the cusp of being completed so I figured why not test it with the new stuff you guys have been slaving over.

No need to be embarrassed. we are here to help. So it sounds like you have installed the linuxcnc as a run in place (RIP) system and you also have an earlier installed version.

So by default, all of your path variables will be pointing to the earlier installed version. So open a terminal window and navigate to ~/linuxcnc_dev folder then try typing
$ . ../scripts/rip-environment 
$ linuxcnc 

There is a good tutorial here which describes this:
www.wiki.eusurplus.com/index.php/LinuxCNC_Run_In_Place
note the dots before the first slash. that is important

So you should now open the compiled version.
If you have not yet compiled plasmac, you can make a new folder ~/plasmac and follow the instructions to compile again except connect to Phill's git, not linuxcnc's

Good looking machine!

EDIT: what you are doing is setting the runtime environment variables to look in the ~/linuxcnc-dev folder as all of the RIP executables are in that folder, not installed in the system folders as is the case with the standard install. Al all errors should get printed to the terminal window if you stuff something up.

That "thing" looks very nice.

Please note that I have removed the attachment from this post as there is an error that could inadvertently turn on the torch while probing...
Working on a solution.

Cheers, Phill.

I have just pushed an update:

Probing should be fixed...

Add a pin named probe-start-height, when probing Z will rapid down at the setup speed and when it gets to this height will move down at probe speed. If this is left at 0 then Z will move down at probe speed.
I have not added a spinbox into any of the sim configs yet...

Next step is to allow multiple ohmic-attempts before falling back to float switch. At the moment it is whatever occurs first.
A bit of feedback on this would be good.
If we set ohmic-max-attempts to 1, does that mean:
1: Try a probe, if ohmic unsuccessful go to probe start height then probe again, accepting either ohmic or float switch
or does it mean:
2: Try a probe, if ohmic unsuccessful keep probing until float switch
I am leaning toward 1, then 0 would behave as per 2 which would be the setting if you had no ohmic probe..

Cheers, Phill.

You kinda lost me. I flowed the how to that was included with the download. But I did not see any plasmac and I don't really know how to compile or change a git. Sorry I feel so out of my league here.

Have a read through this document to get a bit of background on building LinuxCNC.
Have you seen the "quick look" section of the first post in this thread.

Cheers, Phill.

You need to run LinuxCNC exactly as described in the first post or as described by Rod above

Cheers, Phill.
