I cut my first steel today. Thanks to both of you for the work you have done to bring a plasma table to my humble workshop. Take the plunge and order the drawings.

The box has arrived and inventoried. Gathering up the hardware I have on hand and figuring what needs to be sourced. Let the fun begin!

JD's Garage.. I definitely have to have this kit. I have been trying to figure how to get a plasma table for a while. Thanks for sharing this with us.

I just downloaded your plans and 3D printed parts are on the way. Only a few materials left to acquire then I will begin building. I can’t thank y’all enough. The plans and information are very detailed, very thorough. I encourage others to explore what these guys have to offer the CNC community

Thanks so much for sharing this, I was thinking about buying one, but didn't want to spend the money after recently buying a CNC Router and a bunch of woodworking tools. I'm going to build this, it will help me understand more about how it all works.

I'm nearing completion of my build from your plans. Proto typing a SKU1204 x 900mm ball screw for the X axis. Wanted to get some weight off of the Z axis. Calibration is way different than the belt drive with 20T pulley.
Big Con: Can't move the X axis without power ( I miss that option)

Finished 1/8" x 2" x 30" slats today.
Waiting on flexible connector for the ball screw to motor connection to finish build.
I'm using ESP32 and FluidNC and most likely Universal Code Sender as it will allow bluetooth for PlayStation4 controller

Only 1 part (3D printed) that was out of spec, the torch clamp hole centers was long. (I designed another one) I used PETG for all 3D prints.

Still waiting for an update on the THC pcb. Building Z axis now.
Thanks a bunch for the very detailed plans and documentation!

Nice job. Love the simplicity of it.I Like what I saw so much I ordered your plans and 3d parts.

[disasterdetail]

i would pay for a parts list on a website or somthing realy clean design the belt tesioning and expexialy the drive motor position is remarkable

[trirunner]

I love the design and how rigid it looks. Just a thought for a future upgrade. I have been wanting to build a large CNC table like this, but want it to be able to double as a 2D plasma cutter, but also a 3D router CNC machine for wood and aluminum. Your table is heavy duty enough to pull it off with a couple of modifications. One, I would spend the extra $$ for the lead screws due to the torque if you were cutting aluminum. Two, I would put another rail on the opposite side just for support to keep the arm from bending if cutting aluminum. Last, you would need the router attachment. Now you have a multi-use CNC table!

Did this all work? I've heard USB and other things will go crazy from the plasma cutter because of noise. etc.

At that kind of speed a “tip-up” could be catastrophic. Lol. However, nice build. I went a little different route with mine. (Just recently found your channel). Great explanations and content. Thanks!

[Engineering_Science]

Can you discuss more how you built the belt drive system for the rollers and what type of bolts? Also how did you make the 3D printed linear guide truck system?

[benharper]

have just purchased the metric plans, hopefully the steel sizes are redly available in Australia for the build

[colbymcmullen]

ill defiantly be ordering a kit from you in the near future

heyya guys! We're down in Ukraine and without importing at great expense we cant get 70 or 65 or 75mm tube for the gantry spacer, we can get 60 or 80mm as standard sizes. wasn't too bad to make a 75 into a 60.
thanks again!

[toutoune]

Thanks for eeverything once again. I allready have a plasma cutter integrated to my AC/DC TIG welder, however the TIG is a HF start. So I guess the plasma ignition uses high frequency too, no ? In this case, I have one question, because I read the interference an electo-magnetic noises may harm the electronic. Does anyone here has experienced HF cutter issues with JD's Garage setting and hardware ? Any Arduino being somehow burnt, or frequent issues or reset during the cutting process ? Is the cable shielding enough ? I may take a risk if it looks like it might work. I mean, I prefer risking to destroy one arduino board, than buying a new plasma cutter, if it appears that the HF plasma start may work anyway. Whatever experience you have is welcome

[rsz]

Would it help to add a single roller at the far end to reduce sagging and stress on the large y-axis support?

[MrPortdaven]

heyya guys!, absolutely loving what you guys are coming up with, the budget engineering is genius! bought some plans and its coming along awesome! just a heads up with the metric plans, we're down in AUS and without importing at great expense we cant get 70mm tube for the gantry spacer, we can get 65 or 75mm as standard sizes. wasn't too bad to make a 75 into a 70. but i thought id give some feedback. keep doing what you're doing! thanks again!

[bigmc]

Guy's ABSOLUTELY BRILLIANT !!! well done. I am definitely going to build one myself. BTW, did you write the code for the Arduino controller or is it available online to download. Thanks

[RoboArc]

I'd suggest use more plastic. Don't hold back on plastic. But I like all of this 🙃

I really had to bulk up on my cnc to make it effective. I need to make a video.

I took a break for work, but I'm back at it again. I also got huge motors now, so I'm doing well.

But I like this desfine, I wish I had more tools. This would of been a nice build.
