- Version 2 of the how to set up linuxcnc and plasmac when using a mesa 7i76e and mesa thc-ad card. This covers the setup, configuration and basic functionality of linuxcnc. Covers the basics for a router set up as well. This video does not cover the initial install of linuxcnc to a computer for that reference this video: • Installing linuxcnc 2....
If you have questions during your setup feel free to ask them below and I will do my best to answer them. Also reference the linuxcnc forum located here: forum.linuxcnc...
Thanks for watching!
I need to learn the wiring first, then come back to this. I'll check out you other videos and save this for later.
Thanks for posting the video! I'm trying to get mine setup and going. This helps a lot. Been trying to figure out witch mesa THCAD card to us with my cheap china plasma cutter. Once i have it all working. Going to upgrade the plasma to something else but kind of stuck with the one i have now. Think im going to go with THCAD 10 but not sure that will work. What are you using? I know ill have to figure out a voltage divider because my plasma doesnt have one. Have all axis working and moving just need to get THC setup.
I’m using the THC 10AD as well, I found a post on Linux cnc forum thag described the differences and that’s what worked for mine. The vintage divider is definitely nice because it lowes the output voltage and helps lower electronic interference, but the thc cards can take raw live bolts and you can code it into the thc setup. I’ll be honest getting the thc dialed in is one of the harder parts of the whole setup
I tried to hit your website to get the full parts list but the site has expired. Is there an updated site? Thanks, I really like the build.
Aspirin,😲😱🤮😺🌽🍄💥
We'll just save this to watch again later when actually needed🤔😎😁
THNX👍💪🍻🦅🦅🦅🦅
Cheers brother!
thank you, that is gold, not a lot of step by step stuff out there. I know it takes a lot of time to make videos like this, thank you
Glad it was helpful! Hopefully you were able to get your stuff setup! Thanks for watching
Great video! One question I have is for the connection to the Mesa board pertaining to arc voltage. Which point on the board would this be wired to?
Damn off the top of my head I do not remember right now i want to say the arc voltage is plugged into the THC board and then the THC board is wired to the encoder on the mesa 7i76e
looks like on the "motor step per revolution" is more like motor steps per inch is that correct? 3.2/pi x 200 - great tutorial. Regards
Yeah sorry might have miss spoke but yes. So in short, 1 step(or pulse) form the computer does not equal one revolution if the drive. So the math equation shakes out to determine the number of steps to cover 1 inch.
Linux cnc is essentially determining the distance thag is covered by one pulse of the computer program and then uses tbag to run the machine
Gave a like, gonna let it wind while I do lunch... LOL 👍
Yes! It’s a lot but we figured it’s probably best to just upload it off cycle since it’s mostly for the die hard followers to learn to build their own..
What program do you use to draw parts and then transfer it to the plasma control computer?
I use some cad to do designs you can use solid works, fusion 360, google sketch up or Inkscape. I use a lot to Inkscape. Those programs output a dxf file type. Whcih is then imported into Sheetcam. Sheetcam does the nesting and tool path creation. And then Sheetcam exports a g code file which Linux cnc can understand
