Re: Academic question on calculating arc length.

curiosity has got me Keith, what are you experimenting with? Hi Rob, you know the THC that I designed. It's another feature I'd like to add to that. If you got a flameout during a cut, the system would either automatically or upon a button press (depending on setting), reverse along the cut path a ...

Re: Academic question on calculating arc length.

Thanks a bunch Les. That was really hurting my head for a few minutes until something clicked when you said, "If you are using degrees........" So then I thought is Les using those Radian thingies (you see the mathematician in me :lol: ). So I check out Google and find there are pi radians in 180 de...

Re: Academic question on calculating arc length.

Couldn't you use trig to calculate the arc angle given the start, end, and center points? If you know three points then you can calculate the lengths of all three sides. Then you can calculate the angles. https://www.mathsisfun.com/algebra/trig-solving-sss-triangles.html That's the easy bit, I've g...

Academic question on calculating arc length.

Hi Les, I was going to go on a maths forum and ask for help on this but thought I'd ask you first. If the answer is long winded, don't worry, I know you are very busy, and this is not Sheetcam related. In my never ending quest to "play" and figure out how to do things, I'm embarking on a technical m...

Re: Any tangential capability in drag knife module ??

Thanks Les,

some time after I asked this question I realised the functionality was built in to UCCNC, the controller I use.

I did a search in the UCCNC user manual for "tangent" and found it had been implemented a few versions ago.

Any tangential capability in drag knife module ??

Hi Les, it appears there's no documentation for the drag knife module. Is this module purely drag as the name implies, or does it have more functionality built is. For example does it have any tangential control where the Z axis has rotary capability, so the Z axis is automatically rotated along a c...

The Sheetcam here is not a machine, it is cam software to generate gcode for a variety of different machines.

Disable "loop corners" individually

Just like we can change the properties of leadins/leadouts individually, it would be good if the same could happen with looping on corners.

Had a situation today where a couple of corners were too close to an edge and so had to disable all loops to get round this.

Re: extra cut line

It's most likely from the file you brought into Sheetcam.

I have never had Sheetcam add anything by itself that was not in the file I imported.

Post your Sheetcam job file and the DXF or SVG file here for others to take a look.

Hi Les,

just downloaded the next update.

Thanks very much for the additional check box in the On Arcs rule. Just tried it and works perfect.
