When I open Sheetcam I see 2 additional boxes as well as the red work area (see attached image).

What are these and how do I get rid of them?

All of my earlier cuts have square corners but suddenly all my corners have a G03 command and cut in arc moves. Have I inadvertently enabled a function I'm not aware of? In the "Operations" I see there is something called Loop Sharp Corners but it is set to 0 and None is checked below it. ...

I tried the M8/M9 suggestion and got the same bad results. It seems that whatever is controlling things just ignores the G31 travel and executes the next line of code. The only thing that works so far is the pause after G31. Is G31 controlled by Mach3 or the motion control card? I suspect it's the c...

After adding the pauses the program runs as expected. The value of the pauses was interesting. It depended on how far above the work piece the Z started. Makes sense. The longer the Z had to travel the longer the delay needed. I ended up manually bringing the Z close to the work piece before startin...

Some additional info; I tried these two snippets of code. One worked, the other didn't. This didn't work; N0010 (Filename: 2 6x6.tap) N0020 (Post processor: Mach3 THC with scriber.scpost) N0030 (Date: 01/04/2020) N0040 G20 (Units: Inches) N0050 F1 N0060 G53 G90 G40 N0070 (Part: 2 6x6) N0080 (Operati...

That a point I forgot to mention; it makes a difference. When I single step it works fine. G31 lowers the Z until the switch is actuated and the next step zeros the Z, just as you would expect. When the code is run as normal ( I moved the Z pretty high so there's plenty of time to watch as it goes d...

I know the code looks correct but it doesn't work that way. Think of it this way. The G92 is executed before the G31. That's not the way the code is written but it's the way the program acts. I can see the Z go to 0 before the switch in G31 is tripped. From that point all the other Z moves are incor...

Thanks for the help Les. I got the basic Mach3 Plasma post working just fine but I'm having trouble with the 'Mach3 THC with scriber' post. The problem I see is that the G92 function is not working properly. I took the following bit of code from that generated by the post-processor so I could see wh...

I'm close to getting my DIY plasma cutter working using Mach3, SheetCam, a Proma THC and a floating Z. 1- What's the appropriate SheetCam post processor? 2 - Some of the post-processors show with THC. I thought the THC control was independent of the Mach3 G code. I believe that's the case with the P...
