Does it fire on and off or do you have to hit the key twice?

If you are using Mach3 then the torch on/off is triggered on shortcut key "F5"

You will have to press it twice for on and then off.

I did think about resurrecting this thread and ask about having a look at some / and plugin documentation you may have Les.

I've been playing with the idea of creating something similar to tubefit .... At the moment I was going to do it via uccnc Wizard

Thanks , much appreciated taking the time and spreading the knowledge

As per title....

Les, Are the variables "No Offset", "Inside Offset" and "Outside Offset" available within UCCNC from the operations for use within a post processor? Say you wanted to use (insert) them within the start of the operation .... then this would probably provide the needs of ...

what it is doing is when you click go in mach3 the torch moves to its 1st cut location the head cycles down to touch off the plate then rises up to pierce height and then the x,y axis starts moving a few inches and then it drops down to cut height, so the is no pierce delay to allow the arc voltage...

Les, I notice that these functions from the earlier posted post processor don't appear in the Post Documentation for the current development release function OnOffsetNone() post.Text(" G40 (offset off)\n"); end function OnOffsetLeft() post.Text(" G41 (offset left)\n"); end functi...

Is it possible to add the offset compensation before rapid move like this ? N20 M6 T2 N30 G42 (offset right) N40 G0 X62.55 Y77.28 Thanks Laurits. Why do you want offset compensation for a RAPID move? Rapid moves are normally non-cutting / positional moves that are done to get the machine cutter to ...

Oops.... sorry .... forgot I'd tried to help here..... :lol: :lol: :roll: :oops: Old age....? Also I didn't get any notifications.... anyway.... here goes. Current post processor code {unmodified} function OnPenDown() if (preheat > 0.001) then post.ModalText (" G00") post.ModalNumber (&quo...

This modified code should do it: (commented out 1 line) function OnPenDown() if(dist >= (refdistance/scale)) then dist = 0 -- modaltext (" G00") -- text(" Z") -- number (pierceheight * scale, "0.0000") -- eol() post.ModalText(" G28.1 Z") post.Number(3 * scale,...

Post the actual post processor you are using, I'll modify it and repost it back.

The fix is easy, but takes longer to explain than do

Why don't you just create a macro (m-code) to run a cutoff operation via the MDI ?

What CNC motion control software are you using?

Is it licenced?

I believe that sometimes if using software such as mach3 without a legitimate licence there could be bugs added to the motion to give a poor cut

Can you post some of your code?

Inkscape?
