Title: Toolpath window difference
Post by: daseitz on December 24, 2022, 10:33:29 PM
Another difference from M3 to M4 I can't seem to figure out if there's a way to replicate it.
On M3 when you scrolled thru the gcode the toolpath used to highlight the move segment in the toolpath. I can't find anyway to make M4 do that. I'm going to keep trying to find it but any help on whether it's possible would be appreciated.
Thanks again.

OK I found it looks like it is highlighting the current segment. But the color is so close to the line color it's hard to see.
I tried to change the colors in the screen editor but it doesn't seem to change in the window.
Am I missing something?

I finally found the answer to this one also.
I was changing the line width from 1 to 2 and it didn't change - barely see the line.
I saw someone said be generous so I set it at 30 and no change. After all night trying things I went all the way to 300 and now it shows up like a line should. Wow, generous really means a lot.
Thanks for the fourm help.

This has EVERYTHING to do with your video GPU and its associated Windows driver.  If I entered 300 on my machine, the whole tool path window would be filled with a line segment.  :(  Newer video cards and OpenGL drivers are not properly supporting the OpenGL function called glLineWidth(), which is what that tool path setting is using.  So I'm glad you found a setting that worked for you because some GPUs don't even allow the line width to be changed now!
