Run From Here & Cut Tuning
Updated v2.3.1At a glance
- Start anywhere: shuttle the torch along the path or pick a point and jump into the program mid-cut
- The re-entry re-runs the fire prelude — touch-off, pierce, THC on — then finishes the cut
- Right-click the toolpath to change feedrate or AVTHC volts for a whole cut or just one segment
- Overrides live on the visualization, so you tune the next pass where you can see it
A lost arc halfway through a sheet shouldn't mean re-running the whole program. There are two ways to jump in mid-cut: shuttle the torch along the path and stop where the cut died — the Play button lights a jump-in ring and starts from right there — or right-click the point directly, on a toolpath move in the 3D view (Run from here; rapids are excluded) or on a motion line in the g-code editor.
What the re-entry actually runs
The jump-in builds a real program, not a blind seek: the modal preamble (units, distance mode, plane,
work offset) as of the split point, a rapid to it, then the nearest preceding fire prelude verbatim —
the touch-off/pierce subroutine call, its M103 Q target, M101 THC-on — followed by the rest of the
program. An arc split mid-move is re-centered with fresh I/J so it still validates. Because the
re-pierce lands in the already-cut kerf where a fresh arc can't strike, the run auto-arms the arc-OK
latch and releases it on the first real arc-OK. Splits that can't be rebuilt safely — no fire prelude
before the point, incremental mode, a Z or rotary move — are refused rather than guessed at, and the
line highlight during the run still tracks the original program.
Cut tuning from the viz
Right-click a cut for the tuning menu. Change Feedrate… and Change AVTHC… each take a scope — this segment, this cut, or the entire program — so you can slow one warped-plate pass or drop THC on a single lead-in without touching CAM. Segment edits are reversible and idempotent: re-opening the dialog shows the override's real state, and setting a value back to the cut's own clears it cleanly. Reverse Cut flips a whole cut chain's direction — leads mirrored, pierce relocated to the new start — and reversing again restores the original. All of it is a text edit to the loaded program, ready for the next Run or jump-in.
