- LowRider 3 CNC DIY Plasma - LinuxCNC: Probing, Framing, & Cut Recovery!
Q: How much did it cost you to build a LowRider 3 plasma rig?
A: My cost on this, all in, was about $1,860.58, and it's comparable in size, capacity and performance to a Langmuir Crossfire Pro with THC, which with plasma cutter with machine torch + flat rate shipping, comes to about $4,568.00, so my savings by going a DIY route was about $2,707. And, I like doing projects like this. For someone who does not, it may not be worth it to them. In order to reduce costs, I bought a lesser known name (Hynade brand) CUT60DN plasma ($499.99 on Amazon) and a used Acer touchscreen laptop (for loading LinuxCNC) - "Acer aspire V15 Touch Intel i5 4210U 1.70GHz 8GB RAM 1TB HDD Touchscreen Win 10" (only $119.19 on eBay). Those are included in the overall cost I quoted above, as are both the stainless steel table, and the stainless steel water trays I use for my water table. More details and purchase links are in my build log linked in the description. (ALSO: I did not count the cost of the air compressor, which would be an add-on either way, for someone who does not have one that is sufficient.)
Full details on my DIY CNC plasma rig:
• My plasma rig uses LinuxCNC - free open source Control software that includes the QTPlasmaC GUI for plasma cutting! Get it at linuxcnc.org
• UA-cam video series on how I made my CNC Plasma rig, based on LowRider v3 mostly printed CNC: • LowRider 3 CNC Plasma ...
• Also check out my build log thread with full details - over on the V1 Engineering forum: forum.v1e.com/...
• I also have a “CNC Plasma Cutter” collection of parts over on Printables: www.printables...

Good news: there is indeed a quicker way to get back to a segment that needs re-cut. The caveat is that the method is disabled by default. I reached out to the developers via the LinuxCNC forum, and they are considering switching to enabled by default. I will try to post a video about this soon! Happy making!
You are a hero among men for sharing your journey and the information that you collected along the way. Kudos to you!
Thanks, I appreciate that!
Wow its amazes me that a 3d prtinted thing can be so powerful :)
It is amazing! Put a router on a LowRider v3 mostly printed CNC and it can cut profiles in aluminum and has even been shown to cut steel.
@@design8studio I'm looking for a cnc machine to build but im too scared to start. Ive been looking at MPCNC and Root4 im leaning to Root4 mostly tho. But its hard to find side boards for the root4 coz the developer don't seem to restock his shop often :)
The LowRider from V1 Engineering is a great choice. docs.v1e.com/lowrider
A flap disc on an angle grinder does amazing cleanup work to steel, though in this situation with thin delicate parts, maybe a flap disc on an arbor chucked in a variable speed drill would be more appropriate. But the end result is almost a mirror finish.
Forgot if this is the correct name but Qtplasmac has something like "Run From Line", so you can start from wherever you want in the gcode and not have to fast forward with Cut Recovery.
Something else I've done in the past with other plasma systems is do a "Save As" with the current gcode file, after deleting all the code that's already completed, so the cut starts at the first section that needs to be fixed. However, that should not be necessary with Qtplasmac now.
Yep, and I found out about that shortly after this - I think I explained that in a video released afterward. Thanks!
Thanks for posting, very informative
Glad it was helpful!
weld with a lot shorter wire sticking out keep the torch tip close to the weld puddle.
Yes, thanks.
@@design8studio Thanks for the videos on QTPlasmaC I am using it a need to learn more. have fun Tom
@@bigirish4886 cool. Thanks for watching!
If you don't mind which version of Debian and are you running Gnome or what.
Thanks Tom
@@bigirish4886 I downloaded a pre-release version of LinuxCNC running on Buster - that was the only way that I could get QTplasmaC in a version that would work for me. So I think I’m on version 10.12 if memory serves.
very nice!
👍❤️ Thanks for watching!
I may have missed it but what THC settings did you use with the Hynade? I'm building one and trying to get the correct settings for my thc (target voltage setpoint, 1:1 arc voltage, and any other settings for the hynade you found useful)
In another video in this series, linked below, I went over all my settings done in the PNCconf wizard steps, showing screen shots of each page, with the THC settings being shown at the 5:54 mark. The link below has a timecode param to set it to take the video to that point: ua-cam.com/video/gU-OKSPN5ak/v-deo.html
My THC settings are based on using a specified resister soldered inline on the external negative lead coming from the Hynade to the MESA Electronics THCAD-2, and I covered details on that not only in videos in the series but also on my build thread documented in the V1Engineering forum here: forum.v1e.com/t/lowrider-3-plasma-build-on-a-budget-clarksburg-wv/33849
As far videos in the series that give details on the THC, and specifically the MESA THCAD-2, this video is a good source of info: ua-cam.com/video/DC7X0wB65kA/v-deo.html
As I mentioned in this video (linked below and also in a previous reply above), you can get a MESA THCAD card that does not require soldering a resister inline for using a 1:1 ratio from the plasma machine, or the resister can be added so a 1:1 ratio machine can be used with a MESA THCAD card that's made for expecting a voltage divider / reducer. ua-cam.com/video/DC7X0wB65kA/v-deo.html
@@design8studio thanks.
