They actually work quite good. The forces involved for a plasma table are small. My typical speed for 1/8 in steel down to 20ga is 35 - 65 Inches per minute, I find no need to go faster, dosen't...

From what I have seen the Shopbot looks really good, it can do router or plasma. As a router theirs a lot more dynamics and stresses than a plasma table which has almost no weight or resistance. What...

I use patio door rollers, they fit nicely on 1/4 round or 2 x 2 - 1/4 angle. They have to be taken apart and loc-tited without warping them as they will come apart. They're available at any home...

I have spent 4750.76 so far, that includes - metal, electronics, thc300, hypertherm 380 plasma torch, computer, software, compressor filters and air regulator and hoses, upgraded electricity, custom...

Well I'll give this a stab - this is how I described it to my girlfriend and why she hasn't seen hide nor hair of me for the last three months - it's kind of like driving a car sweetheart - I did the...

Thanks a bunch i'll give it a try.

I'm on the last leg of putting my plasma table together with Mr Campbells THC300 and need some final hook-up advice, whoopeee. I have two switches on th X-axis, two on the Y-axis and a switch on the...

Thanks Gerry I'll give a look.

Need to fall upon you experts in Cad to see which software can do this. I want to weld together a tapered arch cut from flat steel sheeting using a cnc plasma torch. As cad programs go I guess the...

Thanks Anthony,
As I go along learning what it really takes to do this I am reminded of the fact that if you are going to do this "Do It Right" and thats what I did, I got Mr Campbell's THC-300,...

Thanks I'll do some more research, just trying to get a feel for the 380 and how it all works together. I was thinking not everyone has THC hardware and how do they go about it.

Am on the verge of buying my first torch - Hypertherm Powermax 380 - and don't quite understand how to controll the cutting process. Using Sheetcam there are settings that allow initial pierce...

Thanks AL,
That link led to a PDF that gave me a circular pitch of .1571 as opposed to my measured .156 which gives (shaft,motor) revs per unit at .21231 instead of .21367 and a final motor rev per...

Trying to set up Mach2 for my plasma table. Section 5.6.1.1 describes "Calculating Steps Per Unit". To find the tooth pitch for rack you count 100 gaps and take this measurment, I get about 15.6...

This is what I just found <http://www.alphaequipmentcompany.com/details.php?view=09E000130000800007&referer=09A>, they are selling these on Ebay. They call it a rack mount lock box for tools.

I suppose then that current controll is not a problem, but what about rapids? Is microstepping equivalent to gearing? If I am already at .25 degree step angle coming out of the motor can I just set...

Can anyone tell me if this works? Geared 6 wire stepper motor (7.2 : 1) ratio, Xylotex controller, 28v power supply. As I understand it chopper type controllers work by quickly turning the voltage...

If you check the motor link the max holding torque is 44 lb/in = to 704 oz/in, that should make quite a good nut cracker I would say. Thanks Jeff for your calculus, I should be able to dial this in...

OK - Here we go off into the wild blue yonder of building my own plasma table, but only after reading thru this forum for the past couple weeks of course! This is what I got so far: 5 x 5 size with...

I am looking for plans to buy . Table size 4 x 4 or 4 x 8 if I get excited. Someone somewhere must have documented their building steps and equipment used somewhere in this universe.

Hello,

I have been trying for years to avoid CNC plasma production and have finally given in. Deciding that I needed a small CNC plasma table I started looking a couple weeks ago at complete...
