Software portion of the CNC Build. Dry and long video bear with me! Worth it at the end. Once I shoot the overview video I will have the Bill of Materials and examples documents available at the website. For this build I am using a Mesa 7i76e and Mesa THCAD-10 to control Torch Height. All other electronics are covered in my electronics video. Reference the below user guides and install videos for details on creating a base configuration and how to update to PlasmaC. Running LinuxCNC Master Branch, anything from 2.9.+ will work the exact same.

hi again, I've just finished watching this video one more time. It is indeed the most important part of the plasma setup. Very clever idea to film this part of the plasma setup. Most of the people can handle the mechanical part of the machines in general more or less accurate, but the computer software part of settings are the big problem. Please do it once again for everybody. You have here the whole plasma setting process. If I learn something.?...when you have the whole process as a story you actually can learn everything not only something. thank you.

Awesome build. Thanks for this video in particular. I'm planning my cnc plasma build and I'm considering building somewhat of a hybrid between your first and second table. I like the simplicity of the direct drive rack and pinion setup you used in the first table, but I think the controller you built for this table is awesome. Can't wait to see the rest of these videos! Hopefully you can compare both your builds at the end! Side note: I built a lowrider 2 cnc router (I noticed the lowrider was referenced in the schematics of electronics assembly video) It's a really fun and cheap machine to learn on but I want to get into something more stout for my metal cutting needs. Thanks again for sharing the builds.

The first build was actually sold to (partly) fund this build. It was kinda a big learning curve on the first one so this one was able to become much more efficient. The overview video for this one is scheduled to release on monday for it. It goes over the differences and nuances a bit more.. These damn things are just so complicated to get right, so the videos for them are incredibly long and dry... but hey, if that's what you got to do to make it work so be it.

hi, no boring at all ...this is how learning is supposed to be. Real good job, though as I am just learning what you are now explaining on your video, I would have really liked to see the configurations you made on your lap top screen. One can not clearly see the image on the screen. I believe that you have got to do something about that unless you lose some great number of you tubers. I need that screen explanations, clearly because english is my second language, and even thinking in english is a hard job. thank you.

Do you reverse the step and direction of one of the tandem motors? thanks in advance!
@Legacy4x4andOffRoadYT
@Legacy4x4andOffRoadYT 3 жыл бұрын
Sorry for the late reply. but yes in the software you will have to reverse the direction for one of the two Y Axis Tandem motors in order to get it to move properly. They are mounted in reverse of each other so one will get swapped or it will bind. This is a simple box to check as you go through the Mesa setup that will swap the direction of travel, the box asks to "reverse motor" or something to that effect. Keep all other settings the same and they will work flawlessly.

Great build, I was wondering if Fusion 360 will work with your table or does it have to be the program your using?
@Legacy4x4andOffRoadYT
@Legacy4x4andOffRoadYT Жыл бұрын
Yes fusion 360 will work just fine, ultimately you need any of numerous cad programs do to a basic design(you can even use Inkscape for simple 2d ones) and then you’ll need Sheetcam to convert a dxf over to the g code for the machine. There are some other programs but Sheetcam is cheap and extremely good for this
@Legacy4x4andOffRoadYT
@Legacy4x4andOffRoadYT Жыл бұрын
So you kind of bounce through multiple programs to get to the g code that is required for the machine. Sheetcam does have some very basic modeling capabilities that can do like simple brackets and shapes and such, linuxcnc also hs some very basic shapes and models thag can be cut as well

I am new to Linuxcnc, I have run PNCCONFIG and then the final config. After restarting PlasamC I do not have the extra tabs shown in you video (configuration,statistics, ect). I also was unable to find the arc voltage pin, I looked at all the ones with encoder in their address but none with arc in them.

What is your username on the linuxcnc forum? Just wonder if I’ve ever seen you around on there. Great video! A few things I’d mention though.... .004” per volt is pretty standard for most plasma machines, it came from Hypertherm’s testing. I know you’re running an Everlast, but .001 per volt isn’t enough and your THC likely won’t keep up. The probe test is really supposed to be used to check your pierce height, it will touch the material and then stop at pierce height. You then use a height block to check that it’s where it’s supposed to be. Then you adjust the value in the config panel for float travel to get the pierce height to match in the real world. This allows you to compensate for your switch hysteresis. Latest version is now .186, lots of good changes so I hope you update frequently :) Let me know if you think there are still confusing parts of the user guide I did a bunch of rearranging recently to tidy things up. Also the main developer is working on a new GUI specifically for PlasmaC that will allow some features to grow a bit. Last but not least. Use auto volts. Simply put it’s amazing. It will totally take the guess work out of “what voltage do I set this to”. Seriously it’s one of the greatest, most underrated features of PlasmaC. I’ve got some cutting videos if you feel like checking them out. I’m really glad someone did a video on all of this, definitely good work!

Username for linuxcnc is "Riggorous", I admittedly do not post too much there but I should contribute more. After this video, completely off camera I did have to go through and correct a lot for the THC. I was getting a lot of interference in the case from some unnecessary voltage. I have since corrected my values and it is working perfectly but eventually I will be rebuilding the case to solve the voltage issue. Those issues were more in the design than the software. To your third point, yes you are right and I think I just did a poor job explaining it in this video. I do owe myself and update haha just havent in a minute but I will look in to it! Thanks for the tip. The guide is actually perfect, truthfully I am more mechanically included than software side of things so it was just a learning curve for me personally. I have a mechanical engineering background and am curious about other stuff but there was a bit of a learning curve for me just moving to software. I have the mahcine working really well now though after some trial and error and testing though so all good! I need to switch to auto volts but that is part of the random voltage problem I am having, until I solve that I cannot swtich to auto volts yet. But soon! I plan on rebuilding my case with the same components but better isolation. I will look at your videos, constantly trying to learn as much as I can! I will be updating this video in the future to when I rebuild my case and can get my other computer to run a mirror of linuxcnc but been caught up with other projects and life stuff! Thank you for watching and thank you for the comments!

@@Legacy4x4andOffRoadYT Glad you got it all going! Yea, voltage issues can really be a PITA, but once you get that stable, it'll cut like butter. I have a mechanical engineering degree myself, and I felt all of the documentation was written from a "someone who already knows how to use linuxcnc" standpoint, which I later found out was true since the developer wrote the first user guide. At any rate, good to know it's in ship shape for now. I havent taken the leap of "turn the camera around and start talking" yet, maybe one of these days...
