Hi Oscar,
I don't have a CSMIO/IP and unfamiliar with its plugin. There are a few Mach4 users of the CSMIO but understand that the plugin is still in its
infancy and the personell at CSLabs have rather 'gone off the boil' when it comes to support, a shame because they used to have a great reputation
for support.
None-the-less I don't think the issue you have described has anything to do with, or at least not directly, your CSMIO plugin. My understanding is that
the tool path drawing is a feature of Machs core, not any motion plugin.
What version Mach4 are you using? I'm going to assume its the latest build....
With the default router profile open Configure/Control (note this used to be called Mach in earlier builds)/Toolpath. Pay very close attention to the settings made there.
Now open your profile (with the CSMIO) and compare the settings.
I have for instance manipulated those settings on occasion. I found for instance when viewing the toolpath for a printed circuit board etch path that the rapid
moves, typically red in colour confused the look of the tool path. I elected to make them the same colour as the background...a bit crude and not perfect
but it improved the look of the toolpath that I could determine those critical details which had hitherto been obscured.
I'm wondering if somehow the colours have been changed.....can't hurt to look. There was a thread on the forum recently that discussed the line weight that the
toolplath was drawn with. As I recall NFS has made changes that allow some of those settings to be manipulated. I'll try to fid it....it may give you some ideas
you can pursue.
