Considering plasma CNC system

[cabinhollow]

Sounds like you had issues, care to elaborate?

With CandCNC you just about have to start on M5 in the G code for each cut.
So, you turn the torch off, start at M5 for that line and just as it gets to the point, you turn the torch back on. The torch maybe traveling 190"/min.
Or, when it gets to the point, you click pause, click to turn the torch back on, then click resume. By that time the start hole will be .2 or larger.
Or, you can closeout that cut file, go back to your design program, change the line, convert back to a cut file, re-load the cut file back into CandCNC and hope for the best.
About all you can do in CandCNC is skip a line, not part of it. And to do that, you have to be reading the code as it cuts and tracking which line you want to skip.

my dynatorch system lets me pause, back track and resume if i have any issues. i dont have to restart if there's a problem. i too have the break away head, plus a laser torch height detector so the head does not have to touch the plate at any time except when calibrating the torch height unit. Dynatorch used to be based out of Kentucky. i think they moved though if i recall.

Are you running Mach3 or Linux/ commandcnc?

I've been looking over the Linux CommandCNC and haven't seen the issue you're refering to with restarts.

If you are between cuts and click pause and then resume, it not a big deal.
It's all the other times that cause the headache.
One is sometimes when you use the esc key, the code re-winds back to the start. You then have to find the line of code that you need to start on. I will have over 40,000 lines loaded at one time.
Most of the time I will layout a full sheet (5'x10') at one time, 6000" to 8000"+ of cut. Some of the cuts will be as short as .12" long.
I also have two Circut machines, under $200 each, their program/software is years ahead of CandCNC.
I use them to cut hightemp tape, for putting designs on items, when I powder coat them.
