I have a Crossfire Pro, Razorweld45 and been cutting enough F Bomb can openers to stock a thirsty Army and adjusting the parameters. I’m using 14 gage mild steel, 30 amps, .150 pierce height, .060 cut height, 80 ipm. I’m getting a divot at the beginning of the cuts, I’ve tried arc and perpendicular leadins up to .200” what gets rid of these? See photo
What is your pierce delay set at?
I have it set at 0.3 second
That was a typo it is set at 0.5 seconds
I’m not sure how the razorweld plasma cutter works but it might be too much delay.
I use a 45xp and I have 0 delay on anything 11g and thinner.

Do you have any “Lead In” or “Lead Out”?
I have a .200" lead in set I’ve tried both arc and perpendicular
Ok, I have tried 0s pierce delay with the same results.
are you using sheetcam or fusion
I am using Sheetcam
Guess I should have known that since you said arc and perpendicular.
So exact same part with .5 and 0 delay?
Yes and I just tried with a 1s delay and same results.
Is that the only thing you have cut out? Same results with different parts?
What is your plunge rate?
I have cut some other shapes that I have downloaded, I’m CAD challenged at the time. Plunge rate was 3.937 ipm it was the default I didn’t know any better to change it so I kept it at that
Also check your over cut, iv had the best results with 0
Overcut set at zero
The other shapes you have cut have the same results?
This is much too slow. Set it at 50 IPM. You’ve basically added over a second of piece delay (1.37 to be exact).
Distance moved = 0.15 - 0.06 = 0.09"
Time to move = 0.09"/3.937 ipm x 60 sec/min = 1.37 sec
At 50 IPM
Time to move = 0.09"/50 ipm x 60 sec/min = 0.11 sec

I think Greg nailed it on the head. Mine is set to 60 ipm.
Great I will try setting this speed tomorrow and report back. What exactly is that parameter controlling and how should that be adjusted with different thicknesses?
