Howdy folks!
I became sick of being reliant on CNC parts being cut for me from a local Fab Shop which jacked up my prices every year. So I purchased my own CNC machine from Langmuir. and FIRED THEM!!!
I have a razorcut 45 on a just built Crossfire pro table… (as yall know, that took 4 days! yikes)
Now, I am trying to cut parts out of 12 gauge mild sheet and totally messed it up!
(I’ve seen the cool videos of this set up working all smooth and clean. So I KNOW it MUST BE user error)
My 1st cuts are literally using CAD designs I DID of my own parts on Fusion 360.
(which also took me several 12 hour DAYS and multiple videos to finally figure out. )
you see, I am a hammer and forge blacksmith so this tech stuff is killing me here.
So yeah, from what I am reading here, I messed up BIG!
As in: 45amp, .9 delay, 60ipm, 80psi, 1.5 cut height…
when I run it, the plasma cutter cuts and then literally welds the cuts back together again! and the slag is MASSIVE where the occasional cut happens…
Man, I suck at this!
So I came here for help, on how to get a “clean cut” on 12 gauge and I am seeing what looks like contradictions. (But then, again, I still suck at this , so what the heck do I know…)
Here is what I am seeing here:
12G = 45Amp, .4 delay, 150 IPM, .9 cut height, 80PSI
12G = 30Amp, .6 delay, 80 IPM, .9 CH, 80PSI
12G = 35Amp, .2 delay, 120 IPM, .9 CH , 80PSI
which is it?
Also, if yall could help me out with “10 gauge Mild sheet” stats for clean cuts that would be great!
As I have a $200 sheet of THAT being delivered soon…
I designed and build my own 6x4x4 electric/propane powered rolling powder coating oven by hand. (it took over 3000 rivets and one year to build) I also own the patent on my own excellent invention, which I make and sell tons of. (with a waiting list.) So, I am not a moron… But THIS is kicking my tail in…
I just need some serious mentoring here!
Thanks
