Oakley,
Thanks! I just used it to burn out a cool motor-mount, (for a kid-vehicle I'm building), yesterday. Still works great. Now that I have it, I design more cool cut-plate stuff into everything...
I use FlashCut's demo http://www.flashcutcnc.com/downloads/FC1Demo_Setup.exe
It has a .dxf to g-code converter and a tool path simulator. You can screen-capture the tool path and print it out. MIKE
Shashank, thanks (I think). Still works for me after 3 years. MIKE
Thanks! There was no plan. I actually started with a pile of parts and built the table around the torch and lead screws. Everything kind of dictated where everything else had to go. You can glean...
I think I have seen a CNC tube coper. Turned the tube and moved the torch to make the copes. If you came up with a stepper tube turner, and could calculate steps/inch of circumference it wouldn't be...
I ran a single leadscrew for each axis, over the top. I have not seen other over the top systems,but it does work well.

I did just that on a...
Try to find a torque curve for your steppers. Most steppers make good power 'till around 1000rpm. Some less, some more. You want to do your work with the stepper in the meaty part of the powerband....
I deal with torch height from the bottom. It's no production machine so I can deal with clamping the work piece to bars that I raise and lower with shims. From 1/8-~3/8, it goes right on the bed,...
One of the good things about TurboCNC is that it runs under DOS. With no multitasking, DOS has full command of the processor and generating steps. Step generators are for Windows based software,...
1/8" is not impossible. I get good results on 1/8". I use my smallest tip (000?) and reduced gas pressures. Consult your torch's manual for speed/tip/pressure settings. This...
Hello! I read alot more than I post here. I almost chimed in on the "Dross" thread, but with all of that plasma technique stuff I didn't feel like I'd fit in. :) I get dross free cuts all of the time...
If you are using mild steel, 1/4"-3/8 thick", I'd go oxy/acetylene. I get great results and have cut some 3/4' & 1" stuff with the same machine too. If you need to do other metals or thin stuff...
I bumped into the pics when I saw your thread at the top of the page. You didn't tell me they were up! Since 9-06! Welcome to the dirt cheap oxy/fuel torch table club (I think we are in a small one)....
Sounds like the job is better suited to your oxy/fuel torch. Thicker stuff is the forte of oxy/fuel. Even my converted hand torch makes light work of 3/4" plate. Here is a 3/4" job I did with mine:...
The chart for my torch recommends speeds ranging from 15/19ipm for 1" steel to 20/30ipm for 1/8" (the chart goes to 12" thick@3/5ipm, but I don't go there). Rapids are rapids and faster is better. It...

massajamesb, your mailbox is full.

Thanks guys ! The torch table is certainly on my short list of most fun (and usefull too) things I have built. MIKE
What massajamesb said. I too, wanted to cut some brackets, and do it on the cheap. I built a 30" x 30" Oxy/Acetylene table for way under $2k (including the torch ) . Plasma could have been used as...
My machine uses a plain, garden variety, hand torch. I use the regulators on the bottles and the knobs on the torch, the old-fashioned way. My solenoid and cylinder uses shop air pressure to actuate...
I use an air/electric solenoid to operate a small cylinder that pushes the torch button. I operate the gases manually.
RE: Flashback arrestors, they are included in my (& most) torch kit. I have...
CNC Zones's robot screws-up links to Yahoo Groups. It is groups.yahoo.....etc. MIKE
I use a torch & 00 tip for .125" & .250" steel quite a bit. Can't help with the decarburization, but the edge is straight. The parts I have been making lately are for an R/C car (pretty small), the...
This is one for MY machine. Each control software may use different commands.
G00 Rapid Move
G01 Feedrate Linear Move
G02,03 Feedrate Arc
G04 Pause (I have a torch)
M07 Torch Oxy On (Coolant A...
I see those ball transfers. The ones I used have a little hole in each one. You can blow the dust out of them. On my machine, the balls are pretty well enclosed in their angle iron mount, so they are...
I think that you would first draw it in CAD as a line. The distance from start to finish would be the circumference of the tube. The line would be a series of arc segments, like a wave that had an...
If your grid is X-Y, and you cut alot of squares and rectangles, you will end up running along the grid more often. Freeform shapes and it is a wash. I have combs and slats, I can angle or grid them....
Pre-heat flame stays on all of the time. I move the torch off of the work, light & tune the flame and start the program. It moves to the first pierce and pre-heats for the time programmed. Then the...
Ahhhhh...UNDER water. I understand. MIKE
You've got me wondering, what will the torch do to the water different than the plasma ? I have seen Oxy tables with water. I was going to build one for mine (eventually). Not many psi involved...
