All the swap details! Wish us luck in the SkyFire competition.

Is there somewhere that all the video entryās reside?
I really never accounted for the differences in time and movement of machine.
I meanā¦
- I understand about less part movement while cutting
- I also get that the weight of the machine needs to be situated and high enough to not move itself
- With all those factors, keeping cost down like with Langmuir Systems Crossfire is a trade off
It is really a nice build for cost versus weight. I did not know what exactly transpired during the cutting of the metals that would create the excess metal on the backside of the cuts.
Now, I know! It is almost like a reattachment of metal from lack of pressure pushing it away while heated.

P.S. Skyfire is a handy machine for sureā¦ Good luck, sir.

When is the party for the SkyFire stuff? Is it already done and over? Did you place or are they upset about the intricate build from CNC to full-bore Laser Induced CNC?

P.S. Happy late Fourth of July everyone. Three days. Oomph. Anyway, I am testing a 3D Printed ACME Screw and lead Nut for nowā¦ This should probably go in 3D Printing stuff. Anyway, if it is not over yet, good luck once again!

Let us know how that lead nut comes in. I might be an alternative for us to replace our lead screw nuts on our tables more often

My lead screw in 3D printing worlds is just mediocre. It is not even glorious like I would have thought it would turn out.
The lead nut is just a chunk of a mass thrown together. If you guys really need one, I can try to put something together in Alibre or Fusion. I usually use Alibre, as they have a neat set up of ideas for their ānewā build for Atom3D, i.e. 28.0.1 or whatever. Anyway, the screw and nut slide proportioned well onto another.
Fasten jargon thereā¦
I have access to ACME builds for āStandardā, āCentralizingā, and āStub.ā
Also, for the print process, there are many other types to ābeholdā (fastening jargon)ā¦
I can make the ātoleranceā tighter or more lose depending on the need. Heads up here but the lead nuts on the ACME screws on the CrossFire may do in fact need an update.
I say that because of the fact they are so tight. Hand movement of the machine is nearly impossibleā¦ I mean, I can move it but a swift glove helps the lack of imprinting of such said hand.
The ACME screws seem okay as isā¦ I have not done that much work to change the build just yet. I like the idea of backlash caution too (ACME nut with spring). Anyway, I can look it over and come to a conclusion. If you guys get a mold maker, let me know. I can just send over a .stp or .stl file to test. I need to measure up the ACME screw still on the CrossFire.
I have some tools here where I can test it. Outside of the old, trusty caliperā¦
Tools for Testing:
- Angle Gauge Set
andā¦
- Some books
I may actually have the incorrect gauge set here but the books will provide me with what exactly is needed to test. Then, off to MSC and/or Grainger for parts/tools.

P.S. Right now, or in the last three months (both really), I have been reading on lathe work on threading. So, I am chock-a-block full of fastening jargon and reading up on equations for 55 and 60 degree angles. I will get to the ACME soon if needed.
I use these to control backlash on the z-axis lead screws of my 3d printerā¦ maybe something to help with the idears.

So I have been researching laser welding and cutting and this was the first time I noticed the reflective light that comes off the material. This was pretty eye opening. After watching further maybe it was when you had the tile under the part.
A different level of āeye openingāā¦
angry space pixies man, you gotta be super diligent on the eye PPE
My view on eye protection.
Bought a 2k fiber laser a few months ago to put on my crossfire pro but also can switch back easily to plasma.The .007 kerf width opens up what parts I can make.
So one day I was playing around welding aluminum tubing. Using hand fed filler and bent down close to have my readers in focus when reflected laser quickly tracks down my right cheek. Really hot and said to self thatās going to leave a scar but probably 10 minutes later when I looked in mirror there wasnāt a mark.
Now looking to get a welding helmet that is laser rated to protect face. Also thinking full bare skin coverage would be advisable when doing some higher power operations.

Sorry for the delay. Agree, backscatter is so dangerous at this wattage. its particularly bad if you attempt cutting rusty steel. Just donāt do it.

Well then that is definitely out of the question for me. I donāt get new steel, all of my stuff is rusty.
And oh yeah, Bite Me.

a lot of these laser units have rust removal mode. Couldnāt you setup a pattern to run that across your rusty plate first then run a cut job? Itās going to take some extra time but the feed rate for the rust removal is rather high in the videos Iāve watched. Iām going to guess it would out weigh the price difference in new steel versus rusty stuff if itās possible. Iām just throwing this out there I donāt know or have access to a laser to test it.
Iāve started to explore running over the cut path with Z set about 1.5" high. This makes the laser dot large as a cleaning path. Iāll let you know if this is an effective way to clean rusty stock.

I have much to learn with/about my laser.
Cleaning rusty metal is just like in the videos after changing focus lens and gun output nozzle. No reason you canāt clean with welding nozzle on as long as you keep laser width smaller than tip of nozzle. Cleaning mode I feel is better because the focus distance is greater so being farther away helps protect safety lens.
Currently feel I should sell my sand blasting cabinet.
Well not yet as my gun melted internal wobble lens when grandson and I intended to melt some sand into glass. So shipped to China yesterday. I miss it already.
Bigdaddyās videos show just how cool the swap works.
