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: Portable plasma cutter

Good morning Rick, I have my plasma cutter on a mig like cart that I store under my plasma table. When I cut on the table, I roll it out and plug in the tables machine torch. When I have something to cut off on my welding bench or a weld to gouge out else where in the shop, I roll it out and plug in...

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.

Have you tried it with the material sitting on the slats with the water cooling it? I've cut 3/4" with just my HT45, edge starting and water splashing on it, and got a fairly nice cut.

Re: Handheld vs Machine torch

Having the machine torch on your table frees up the hand torch to use for cutting done off the table. I have my plasma cutter on a mig welder type of cart, so I can easily move it around my shop to do a quick cut or gouge on other projects.

Re: Tips for spotting looped lines/artifacts in drawings?

Old Irons suggestion to make the lines wider to spot defects works well. Another thing I do to make sure things will cut without problems is to make the line width equal to or slightly greater than the plasma torch cut width for the gauge of metal I'm planing on using. This shows up the lines that a...

Re: Strange: torch goes up then flame out when cutting

When under THC, the torch is raised and lowed in response to the cut voltage vs the set voltage. So if the set voltage is higher than the cut voltage, the THC will raise the torch up to try and get the cut voltage to match the set voltage. If you are clamping the work clamp on the slats, it can affe...
