First post here. I am modifying a mill screenset for my custom lathe screenset. Everything is mostly working, but I haven't been able to figure out where the lathe/mill mode is set. After loading the screen, the mode string shows Mill and a series of G codes, among them G17. I think this is causing that the toolpath display, even if it's set to X-Z, always shows X-Y and I can only see the toolpaths by rotating the axes with the mouse. Also if I change the work plane to X-Z in the configuration, it will be overridden on startup. The initialization string is set to "G80G95".

I checked the VB scripts on different locations and the ones inside of the screenset, but I cannot figure out where the mode is set up. Any suggestions?

You should start with the mach3 loader and select machturn rather than mill.

it is indicated by the filending of your screenset file.
ABC.set -> is mill
ABC.lset -> is lathe

Thank you John, I am starting MachTurn already

Thank you TPS, changing the file extension to *.lset shows lathe on the mode line! However, when I load a GCode file I cannot see the toolpaths anymore. I could see them before when the file extension was *.set even if I had to rotate the display to see the X-Z plane. On the general configuration the selected plane is X-Z and MachScreen shows that the component is set for the X-Z plane.

I have to say that while I can see the toolpaths in Turn I'm far from convinced by them!  But it seems to work regardless!

Actually, being able to see the toolpaths has helped me find issues. Sometimes the GCode is unexpectedly hitting soft limits and it's because the arcs are inverted, which I can see in the toolpath display. I then change the setting on the CAM software and the arcs show as expected.

By the way, I got my CNC lathe 4 months ago and I haven't machined anything yet! I am still trying to figure out software and hardware. I've cut some air though.
