Divot on Backside of Lead In/Lead Out

CrossFire ® PRO
1

Hey everyone,

I’ve been using my pro for a couple months now and was wondering if anyone has figured out if there’s a way to eliminate the divot on the backside of the parts where the lead in/lead out is located?

I’m currently using a Hypertherm Powermax 600 paired with a duramax retrofit torch using fine cut consumables. The cut’s are pretty clean with the age of this machine but I can’t seem to find a way to eliminate that divot on the backside if it’s possible.

Sheetcam Settings:
Material: 14G steel
Consumable: Hypertherm finecut
Kerf: 0.055"
Feed rate: 125 IPM
Pierce delay: 0.6s
Pierce height: 0.09"
Plunge rate: 100 IPM
Cut height: 0.06"
Lead in: Arc @ 0.125"
Lead out: Arc @ 0.125"

I’d appreciate any suggestions that may work! Thanks

you’ll need a longer lead in/out. with that much scrap in the middle, you have enough to go .25 or more.

what angle are you using on your leads?

Sheetcam doesn’t have angles. It’s either “perpendicular” (90 degrees) or “arc” lead in/out.

.3 pierce delay and or pierce in center of hole will avoid divot.
