hello all, I’m the classic nube and i just recently received my crossfire pro with the razor weld cut 45, today i made my first test cut on 1/2" plate its all had around because i didn’t want to mess up the new metal ive be stocking up on, anyway the fist cut was awesome so i thought until i looked at the bottom of the cuts plenty of crap on bottom. i decide to make a cut on some 1/4" steel thinking the would be a not brainer well i have not been able to punch a hole threw this steel it does have some surface rust but that shouldnt matter i think. the im running these settings in sheetcam

In addition to @Bigdaddy2166 's recommendations, you should also increase the plunge rate. I believe Langmuir says it has to be a minimum of 50ipm so I (& many others here) go with 60ipm.
Can you clarify… “not cutting”? Does torch fire? I second or third the pierce dwell time issue… you probably had it higher on the 1/2" cut?
There is a slight delay in plasma cutter for air solenoid to open before plasma fires. If XY motion starts before torch voltage is sensed, the pierce will fail. Increase to 1 sec and adjust from there.
