Title: Mach 4 toolpath not smooth in screen
Post by: ROTM on July 05, 2023, 06:17:12 PM

Good day.
I am exporting a file...svg into sheetcam and then export as .tap file to Mach4.
However in Mach 4 screen the toolpaths are not as smooth as in sheetcam.

I just replaced a new PC with a fresh install of Mach4 ...adn on the old pc it was just fine..
Regen does not do anything...also is there a way to make the toolpath lines in the screen a bit thicker?

Thank you!

This has EVERYTHING to do with the OpenGL support in you video card driver.  See if there is an updated driver available for your GPU.

further to Steve's comment

new pc ? I will bet a £ to a pinch of Salt that the new PC has integrated graphics , not a proper GPU

I had the same problem with a Dell opitplex SFF I got a GPU that fitted into the PCI slot and result smooth graphics
