Hi Gerry,
By "error" you mean an error message popped up saying the file is too large to be opened in the file editor?
If yes, then that is not a bug, that file size simply can't be opened in the file editor, so I've created an error message to avoid an exception and crashing of the application when it was trying to copy a larger text size as what the richtextbox control can handle. And richtextbox can handle the largest text size of all the windows controls. Listbox would collapse from even a much smaller amount of data.
That file size is even hard to be opened in notepad, if it even opens.
And yes, it is hard to even create that file size with copying the whole text behind the original text just to duplicate the size of the file.
Windows has issues with smoothly handling that size of data to be copied onto the clipboard and also notepad has issues handling and saving that file size.
And I was doing the file copy on our strongest computer, on a i7 with a total of 32GByte DDR4 RAMs.
And I will check the file closing issue.
Since now the UCCNC is using vertex buffer object to draw the toolpath it is all done by the GPU and optimally vertex data all in the VRAM, so the GPU does all the drawing of the toolpath drawing without CPU interaction.
Ofcourse this is the optimal case, OpenGL is more complex that this can be said on all and every systems and every cases though.
It is possible that the current refresh rate is a bit too high is why the GPU usage is so high, we can fine tune that later if it will be required.
