I can only produce an image zoomed to the job extents. If you draw the outline of your table in a separate drawing and load that as another part it will be scaled correctly. You will still be able to move your cut part around the table as long as you don't move the table outline part. If you right-c...

Rounding the corners should work. Are you using a finish allowance? Finish allowance increases the effective cutter radius.

You are looking for a feature called rest machining. Unfortunately SheetCam doesn't have that facility and it is pretty difficult to implement.

OK, I had a play with this. I have attached a plugin for you. Go to SheetCam's plugin directory, on 64 bit Windows it will usually be something like C:\Program Files (x86)\SheetCam TNG\plugins or this in 32 bit windows C:\Program Files\SheetCam TNG\plugins In that directory create a new directory ca...

That's odd. It should only say 'not connected to machine' if Mach3 isn't running.

SheetCam and Scanything expect to find Mach in c:\Mach3 so that explains why the plugin didn't install. I assume you did enable the plugin in Mach.
In Scanything is 'use Mach3' selected in the file menu?

Well, it was worth a try. Is your copy of Mach installed in c:\Mach3?

Try installing Scanything or SheetCam again. If Mach was installed after Scanything and SheetCam you won't see the plugin.

Could you try manually editing the code to apply a pull back and see how well it works.

You can do that already. Use one 'small circles' path rule for each diameter. If multiple rules apply to a circle the one with the lowest feed rate will be the one that is used.

Would it not be better to pause for a very short time on the corner to allow the tail to catch up? You could do that using an 'on inside corners' path rule. Use a code snippet with code something like this:

PathPilot is based on LinuxCNC so a LinuxCNC or EMC post should work.

This is a bug in the post processor. I don't have a copy of that post but it looks like the post is written to output this line as simple text: G38.2 Z-0.50 F#<_hal[gscreen.toffrate-s]> As it is just text the post processor has no way of knowing the feed rate has changed.

Don't use DefineVariable. This is used to expose post processor variables to SheetCam. Any variable defined this way will appear in the 'Set post processor variable' operation. Lua creates variables automatically the first time you use them. Here is how I would do it: In function OnInit FirstTool = ...
