4 x8 Plasma and Router

[lamicron]

We started this second machine with some changes , and have to make it in one month. The works began the 14th of feb.
Will use a waterbed, 1160 oz/in motors for X and Y and 495 for Z. Rails and blocks from Hiwin for the Y and Z, and Roton screw for the Z. gear and rack for X and Y.

Hi Luis,
The first plasma machine, Did you sell it already? Do you use THC for the first machine? I expect your experience will make the second machine excellently.

hey Millman, or any other expert, need some help',
Today i was starting the first plasma table I made, I have a Thermal dynamics 50 Pack. I had cut two parts and in the tjhird the mouse got stucked. also the keyboard. I had to restart the PC,
Tryed again and get the same results, maybe the HF?? I have the machine and the plasma grounded at different points.. Any clues?
Thanks
Luis

Luis, sorry I haven't been on for a few days. Have you got your computer "freezing" problem figured out? If so what was causing it?

Your new build looks very good.

My guess on the screen lock problems id noise somehow finding it's way back to the computer. Usually from common ground(s)

Typically you should have your plasma machine grounded to a seperate ground rod than your AC power supply. you should also have your plasma work ground directly to the piece of metal you are cutting. NOT to the machine bed or machine frame.

Yes, I found that, I put a separate rod for the plasma ,
The problem was in the pc grounded. Fixed now ,Thanks
About the :
" you should also have your plasma work ground directly to the piece of metal you are cutting. NOT to the machine bed or machine frame."
I use the ground to the slats where the work is cut, not directly to the work, is ths ok?

It is recomended that the work ground go directly on the sheet being cut. Most slats are "drop in" & don't have a secure metal to metal contact surface.

It will probably work, hooked to the slats, most of the time. You are however leaving that chance of loosing ground & causing problems.
