8. SheetCAM — toolpath & post · Premier Plasma Tech Help

1. Import and verify

Open correct Premier SheetCAM setup / job template
Import the 2" DXF; confirm displayed size before operations
Sheet size/origin match how you will zero the plate
Inspect gaps, duplicates, stray lines, reversed arcs
Select Premier-approved plasma post for the Mach3 table

2. Plasma tool fields

Amperage, kerf, feed, pierce height, cut height, pierce delay, plunge/Z rate — start from the exact plasma cut chart and Premier-tested toolset. Do not exceed consumable rating.

3. Build the jet cutting operation

Correct cut layer + plasma tool
Outside offset for exteriors; interiors identified per approved workflow
Automatic optimization + keep-parts-together (holes before outside)
Lead-in in scrap; small holes have room for the lead
Cut direction places torch good side on finished part
Visualize every contour; run SheetCAM simulation
Post to a new clearly named G-code file — don't overwrite last known-good yet

Tip: Wrong post can create wrong torch commands, touch-off, or pauses — treat Premier posts as controlled files.

4. Mistakes that look like machine failures

Wrong side of line → offset. Part drops before holes finish → cut order. Torch fires then moves immediately → pierce delay. Wild feed → units. Shape missing → layer/open contour.
