I just picked up a 55 gallon plastic drum to store the water under my table… and it doesn’t fit under the table 
Anyway, the plan is to use air pressure from the compressor to push water out and up into the pan, then just gravity feed back to drain. No pumps (or pump maintenance) required.
It shouldn’t take much pressure, and suppose I’ll have to be careful to regulate the pressure as I’m not sure how much it would take to burst the barrel.
Turn it on its side, bungs up? Wow that is an odd sentence. 
Yeah, I had intended to lay some pipe in some side action bung hole but it may not work out…
(Too much?)
Head down, ass up…
I’m so proud of you guys… 
I think I’d be more worried with shooting the liquid all over the machine.
For sure. I wouldn’t want to prematurely blow my CUT IT OUT KYLE
The expensive electronics are in a water resistant enclosure on the opposite end of the table. Plasma sure is messy
I was trying to mentally picture what pressure you would need to move the water.
I think the force pushing from the air is the pressure times the surface area of the water?
And the force needed to lift the water is based on the water column from the lower to the upper basin. The weight of the water in a tube, if the tube was going straight up from one surface to the other might be right. If so, 1psi over a large area would easily lift the water in a 1/2" tube.
Once you get it moving at all, it goes into fluid dynamics and I am lost. But more pressure would go faster, that much is for sure.
I would be convinced that it would take very little psi. Low enough that I would probably set the regulator to zero before starting.
It will have a lag too. The pressure in the drum is what matters, but it will take a long time to get that pressure to equal the pressure at the regulator.
Yeah I was figuring around 5psi should do it. It’s not a pressure rated tank so I wouldn’t push much more than that. Otherwise I do have several pumps laying around from my homebrewing days but that’ll require filtering.
Sorry Ryan, I’ll stop hijacking your thread. I’m sure I’ll post about it over at my build thread if I get it up and running.
No hijack. I am considering all the same stuff, and it is coming soon. I am kinda at the point now where I need to cut some wires and plug in the steppers I think. So physical is basically done (until I find a grounding issue) and now back to software and linux.
James over at his Clough42 youTube channel just posted a video about how adding a self-made monitor stand to his plasma table “broke” his THC, and how he fixed it. Might be an interesting watch for those working their way through their plasma setups.
I was so confident in my setup until I watched that exact video…If I messed up it will not be easy to track down.
I think he was lucky to have had it working until he made the addition of the stand, so he had an isolated change to investigate.
I was under the impression my table will probably be wood with an insert for the cutting surface. Thinking drop table possibly. I think I will have more ground control that way.
Have you mentioned if your base will be lowrider or mpcnc or… Something new?
Have any pictures or is there going to be a big reveal?
For now I am just going to slap something together on the current lowrider. That will give me a solid idea of what I need to start the design of the next one. ASAP.
No pictures yet, got pretty busy around here for a few days so I hope to get a little time one in each day for the next few days. I really want to either move it around or test fire the torch. Cutting will take a while I am sure.
I soldered up a few more pigtails and wired up some test steppers and switches…my linux disc is not booting. So now I need to install linux, and linuxcnc again, along with configure it.
I have no idea what could have happened it worked fine for several days. Tried the disk on a different computer even, no bootable partition, grrr.
Boy…I can’t remember when was the last time I have a computer/laptop with a CD/DVD drive.
I was using a USB stick…although it seems a old computer with a cd drive is preferred!
