Re: Looking for suggestions on tracing tablets

Rick, When I trace with a mouse, I'm doing it in Corel Draw, and I use the polyline tool. I just start on one side of what I'm tracing, and just click my way around the trace, putting a node everywhere I think I need to turn a corner or make a curve. When I get back to where I started and click on t...

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: Looking for suggestions on tracing tablets

I picked up a cheap Monoprice tablet a few years back. Frankly, I never use it, just tracing with the mouse on the computer screen works better for me.

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...

Re: Double (and sometimes triple) cuts

Like motoguy says, you've probably got overlapping lines. I'm not sure why, but Corel Draw seems to like to stack lines on top of each other when doing certain types of operations on a drawing. If you select your Shape tool to edit nodes, then zoom way in on one of the offending lines, you'll see mo...

Re: Small shapes not completely cut. Plasma or software

I can't tell from your picture, but are you using a lead-in on your cuts? A lead-in (or a longer lead-in) might help with your problem. I don't know if you have the option, but an over-cut might also help.
I tried watching your video, but youtube says it isn't available.

Re: Looking for a wall mounted vertical sundail

I suppose you could take a straight on picture of it, then measure the dia. of the outer circle. Then you could trace the picture and size it to the dia. you measured. If we assume the bricks are 8" bricks, then it looks to be a little over 40" in dia. I can't quite figure out from the pic...

But when I selected the circle, it said it was a spline (not a circle). In Inkscape, the program displayed a mes...

Re: Torchmate Stutter when jogging to start cut

Perhaps your jog speed is set too high, or your acceleration is too high? Could even be a loose setscrew on a drive gear? You might try going back thru your motor tuning.

That's all the ideas I have for now, Steve

Re: Bad cuts with Hypertherm 65 (Finecuts are the problem?)

Another thing you might watch is the up/down lights on the Mach screen. Is the up light lighting when the torch is heading up? If so, that would indicate that the controller is telling the Z to rise. If not, then something else is going on.

So short answer, use 2 different posts. One for the ethercut, and one for the DTHC2. You can have more than one post button in Sheetcam, so you can use one button for each post.

I just yesterday installed the Ohmic sensor on my table. I have not yet cut with it, but will shortly. My reason for the change from the floating head was because I am cutting more thinner gauge metal now than I used to. As far as water on the plate (I use a water table), my reasoning is that the pl...

To me it looks like the nozzle in your consumables 1of2 picture has a notch out of the round hole. Might just be the angle of the picture, but if it does and it is new like you said, then something is not right. (no idea right now what that may be)

Since the torch should never touch the sheet while cutting, the sheet really doesn't move around. You can clamp it to the slats if you want to hold it in place or down.

Re: Issues with plasma cutting, maybe grounding?

First off, the clamp cable from the plasma machine is not a ground cable. It is a work clamp, and is the return path for the plasma arc voltage. Your table should be grounded to an earth ground. There is an entire section in the CandCNC manuals on grounding. The table grounding is mostly for noise g...
