Okay, I will check our computer cable to be sure that it hasn't been damaged.
I will try the speed tomorrow. I replaced the electrode but the nozzle looked pretty good. Tomorrow I will replace the nozzle and the ohmic retaining cap to see if there is any difference.
I just emailed the gcode to you. I have already replaced the consumables; I have tried a psi range of 66-72; an amperage range of 40-45 amps; speeds of 120-150; and, tip volts from 83-100.
Here...
Oh yeah, I also changed the span gap to 10/4.
Okay, I have been trying different things to get rid of a fairly severe serrated edge when cutting letters (curves). I have changed back to 20:1, changed the THC rate to -15, changed how we index...
Nice! I have found that I really like working with the thicker material. It cuts like "buttah"!
Thanks Matt!
What exactly does this mean? What should I adjust and what should I adjust it to?
Thanks!
LOL! It's on the list! :wink:
I used .5 for the thc delay.
Now, I wanted to post a pic of a peacock that we cut tonight that I created! Thanks for the help wicked! :B-fly: Let me know what you guys think.

On the 12 guage I use a .06 pierce height & cutting height with a Hypertherm 85 using fine cut consumables set around 42 amps. I hope this helps.
Alright, here are today's projects. I did some extra work on the raccoon. Please let me know what you think. Also, what would you charge for it? It is @ 24"x24", 12 guage, and so far I haven't...
Thanks Matt. Zeroing out the Z took care of that problem. We will keep playing with it to try to get it to stop skipping.
Tonight we finally did the 1"x4" test cuts to tweak the settings to get...
When misses sections, it is on wide open cut paths. It is loosing the arc for a split second or longer but not at the beginning of the cut.
Oh yeah, one more thing... When I do "run from here" and the gantry travels to that spot, the z axis cycles all the way to the top of the screw and keeps trying to go farther for several more...
Well, that might be true in some situations but one of the skips was on the outside border and several others were in fairly large inside cuts. Also, I have decreased the pierce time to .2 and it...
Thanks Matt, that really helped speed it up. Now, my question for today: Why might certain sections in a file not cut? I cut out a couple Signtorch files (very simple deer circles) and I had to go...
Okay I have 2 questions:
1. Where is a good place to go to learn more than just the basics for Sheetcam? Is the Sheetcam manual fairly in depth? Would it confuse even a longterm user?
2. How do...
Thanks Mav, that is helpful. Now I am just trying to figure out the lead in problem. I am trying to figure out how to switch them to internal lead ins... Also, is it okay to use no lead ins at all?
Well, we have a 15 cfm compressor with the gauge set at 100. Does this seem adequate?
Here are some pics of my 2nd cut. I need to get better at checking the whole pic in Sheetcam before...
Okay, I will move the clamp. We had hooked it to the bottom of the water table with a welding magnet.
It almost seems like the water from the water table is splashing up and snuffing the arc. Is this possible?
Yeah, it's weird. Some of the cuts look right and others don't. And then it seems to have cut when it was supposed to be travelling. That was probably from me turning the torch on & off. Maybe I...
Alright! That seemed to do the trick. Now, I had a couple issues during the cut. Now Matt, I will say it before you do, "I should learn to walk before I run!" But, I wanted my first cut to be...
