Re: ELIMINATING NO-OFFSET HOLES

With that thin of material, I'd try eliminating the Pierce delay and see if that helps reduce the divot.

Re: Favorite program for editing DXF files?

It really depends on what kind of DXF's you're working with. If it's pure CAD type mechcanical drawings, you may want a AutoCad type program (there are free ones out there). If you're working with artistic type programs (which is the majority of what you'll find on here), then you can try Inkscape, ...

I think your problem is your torch. I found this with a little searching: "Update: I just looked the system up. It is a high frequency start torch. The consumables look identical to Hypertherms original hand torch...the Max40, that was introduced in 1986!. I think if I was going to copy someone...

Re: End of Cut - Compressed Air Off Delay

You might try putting a small sheet of metal at the 0,0 position to stop the splashing, or move the torch somewhere else after it goes to 0,0.

Re: Files from here

Depending on the country of origin, files downloaded from here can be either in either metric or inches. So when you import them into Sheetcam, you may have to change your import scaling in the drawing options popup window.

Re: Machine not travelling correct distance

By my quick calculations, you are off .007" per inch. Have you tried changing your steps per inch slightly to adjust for this?

That's my best thoughts for now, Steve

Re: DXF not showing any Paths?

I don't use Inkscape much, but a couple of things come to mind. Maybe the bracket and the graphics are on separate layers and are not being exported to .dxf together. Maybe there is no color on the line, or maybe there is no line at all on the bracket.

Re: Files

The files you download from here are mostly .dxf or .svg files. These files will need to be processed through Sheetcam into g-code files (.tap ). The g-code file is then imported into Mach-3.

I made one from the end of a toilet plunger. It worked fine, kept everything clean. I took it off while playing with a laser torch alignment setup.

Re: FFA emblem/sign

Irunyon, There should be nothing in the cut file that would cause the problems you describe. It sounds like you are having air pressure problems affecting your arc voltage. This is then causing your voltage to drop, so the torch is rising to try to get the voltage back up. You might try putting an a...

Re: What am I doing wrong?

Have you put any metal other than plain steel in it? If I put anything with copper on it in my bath, then later when I put steel in, my metal comes out copper plated. My thought is that the black is some other kind of metal that is plating your steel.

Re: Downloaded File Problem

I would think that the plasma would try to pierce at each separate line. I always make sure all the lines that can be joined are joined, so I've never tried to cut a dxf like you have described. I do know when I have missed a line that should have been joined it does strange things.

Re: Getting Started

I'd say what you use for your CAD drawing depends on what types of fabrication you do. I have a regular CAD drawing program (Draftsight) which was free, but I never use it. Instead I do all my drawing in CorelDraw. (Inkscape is a free alternative to it). I do some artsy type stuff, but most of my st...

Re: Z axis problems

Fabricator, there are several ways to wire the Ohmic sensor and the Z floating switch. The Ohmic sensor will be used to sense the top of the metal, irregardless of what gauge it is. The plasma cutting process requires a very narrow range of heights above the metal, so the system needs to know where ...

Re: help on doing an edge start

Yea, what he said. I don't do any measureing, I just draw up my cut so the edge is zero, then when I import it to my cutting program, I line my torch up on the edge of the material so the center of the torch is just a hair off the edge, the zero the DRO.

Re: Mach3 trouble shooting help please

It sounds like Mach3 is doing the math wrong. Why don't you just try changing the distance a little bit each time to sneak up on it. Going from 1000 to 4000 is a huge jump. If you were going 1.5" in 1000 steps, then logically you'd be going 6 inches in 4000 steps.
