Ive have got alot of questions from folks on the CNC plasma build, so I put together a summary video. This is more of a details and specs video than a how to. If you have questions, comment and let me know!
Who would watch this entire video? ME!!! I'm your ideal viewer! Thank you so much for the detail. I really appreciate the depth you went into. This makes me feel like I can build my own plasma CNC. You answered many of the questions I had.
There are some good RU-vid videos on how to solder those style of connectors. In general, you really ought to have a proper temperature controlled soldering station (even a cheap one is orders of magnitude better than an uncontrolled “fire starter”), good electronics solder, flux, and a means of removing excess solder (braid, a solder sucker, or an actual desoldering gun). Magnification is also essential - I have a stereo microscope; but even a cheap desk magnifying glass is better than nothing. Also, don’t forget ventilation... soldering makes smoke that you don’t want to breathe.
Hi..Love the build..Building a 4 x 4 heavily inspired by your's table...One thing, the drive pulleys on the motors... 20 tooth ??..and is there a chance you would share the 3d files for the belt tensioner ?? .Thanks
Excellent table build. Quality of construction and attention to detail you have invested in this makes my low budget plasma table look pretty crude. Could have really used this 2 years ago. But I still learned a few things and got some great ideas for my next table project. Many Thanks. BTW, what CAM and control software are you using?
Actually, what you want isn’t necessarily the highest holding torque, but rather the highest torque at speed; which can occur in a motor that’s one step down in size (I.e, a 23 instead of a 34). Exact details, of course, depends on the motors under consideration. 🤔
I noticed that yours is a 2x4. Do you ever find the need to have a 4x4 or larger? Did you follow plans anywhere or have any suggestions? Thanks for your videos!!
Any chance you could post where you bought the parts needed for this. Other than the ones listed in the video. If not thats ok there's still a lot of valuable information here!
Thank you very much for your videos and it’s been helpful for me … I have my own DIY CNC build and I Use the same controllers pokey57CNC … i use GYS plasma cutter with built-in air compressor and it’s not capable for the CNC table but I make Wiring modified to fit on my CNC … I have two main issue the first one are use a Vietnam cheapTHC and it’s not work correctly I’ll try many solutions add many things it’s one to work … The second issue that’s have just come it’s about what is the plasma arc is engage suddenly the 57cnc it’s stop … and I noticed that you talk about the ethernet that’s block of the Frequency The come from the plasma and what about the software Does it work with mach3 ? and thank you very much
Great job, I really enjoyed reading the video. I am thinking about building a plasma cutter very similar to yours is there a way I can get the STL files for the 3D printed parts?
You mentioned the problem with the voltage signal from the Everlast machine for the THC. Have you solved that or do you need a better Plasma Cutter? Thanks. Great Video
How much $ do you have invested in this build?(nvmd I found your earlier response to xanxan) And have you put together a build list? This is flyin high on my radar !
Hi, nice build. I’m building a similar CNC right now. What is the max speed (millimeter per minutes) you can have in your cnc and how thin metal can you cut with good results? And what is the diameter on the pulley on the nema 34 motor? Thanks a lot
My rapids are right at 300ipm and max cut is about 140ipm. If the cut any faster you get some spring in the z axis assembly and it causes and overshoot
Can you tell me the name of that euro company you got your Cnc electronics from I know the pokey57 but that other company that sells the package. Thank you.
Wow! I have just seen your video and you have the exact same setup as me. I also opted for the Pokeys57CNC with PlasmaSens etc. I am really struggling to set the unit up with Mach4, is there any way I could talk to you or you could share your Mach4 settings please. I am at the end of my wick with trying to get Mach4 to work with my system and you have cracked it! Any help would be REALLY great fully received! Thanks 🙏
@@LoudandProudBSE brilliant! Thanks for getting back to me, I was getting really desperate 😂. I would like to see all of your settings for the following please: 1. motors (I want to see how you setup THC in the motor settings). 2. THC including how you assigned it to the analogue registry if possible. 3. how you set the relay up to work with the torch on / off function in Mach4. 4. After seeing your table using the proximity sensors I have just purchased a full set of these, could you say briefly how you wired them, I am a little confused as to where the wires must run and don't want to kill the board by wiring it wrong 😂 5. Lastly, if you use SheetCAM, what post processor do you use? Thank you so much for your help, it's my first table and I am having to do a lot of learning quickly 👍
Air is supplied by a Ingersol Rand SS5 and its filtered and dried through a homemade desicant style holder. Its good for a couple days and then it needs dried. I also have expansion type collectors/filters on each drop on the shop.
What’s crazy is the larger tables are so much more but it’s really the same components, just a little more wire and metal, certainly not enough to justify $2-5k more.
This is a good video to get me started on a cnc plasma. I have 2 thing that i wonder. First, I have a relatively cheap cutter with pilot arc. Would that be a problam? I plan on using a Proma thc (the cutter has an cnc port) Second, I wonder why you went for the nema 34 in stead of the nema 23, i would think the 23 would be stong enough. The take less power, are cheaper, and use cheaper stepper drivers.
I would stay away from anything with high frequency start. It will cause alot of electrical noise shielded lines or not. Nema 23 are sufficient for this application. There are no tooling loads other than the acceleration of the gantry. It this was a router then I'd go that route. I've crashed this machine once of twice. Those nema 23 motors have enough power to break stuff the way they're geared if the belts dont skip lol.
@@LoudandProudBSE Thanks for explaining. How does a non hf/pilot arc start the arc. I rather not buy another cutter but if it won't work, i have no choice.
@@38chevyhotrod I believe hearing in another guys video on his plasma table build that Pilot arc is the way to go. Pretty sure this what Hypertherm uses...
Thanks for the info. I have a Crossfire Pro CNC plasma table on order and was planning on buying the Everlast 82i plasma cutter with the CNC package to go with it when it arrives next month. Should I be concerned about the Everlast cutter? I'd hate to spend $1500 on that cutter and not be able to use it with the torch height controller on the plasma table.
Honeslty I'm not sure. The plasma it self has been great but the voltage is all over. I would just say, be prepared to install leads yourself if need be.
@@LoudandProudBSE Thanks for the quick response. So you think that there is a fix for this issue that does not require another cutter? If not do you know of a better option?
The brute force method is to wire to the full voltage in. Im not familiar enough to recommend it for safety reasons. Not sure what other machine competes in this price range
Hi, thanky ou for this great video. Great work! I would like to know more as I am starting to build my own plasma cutter/CNC machine. Please let me know your e mail or something where I can reach for more info. Telegram if you have it as you do not need to share your number or anything, just a nick name. Thank you!
