Hi,

I haven't changed any settings, but for some reason when I open a file the toolpath no longer gets displayed. It shows the dull grey path of where the machine has being but not the path from the file. I can't find any settings that could turn this off and I haven't changed anything lately. Also on another computer where I run it in simulator mode the toolpath shows up.

What/where should I be looking to fix this?

Cheers

Check Settings/UI/3D section.
You can export profile and send me zip file so that I can check what is wrong.

I had already done that and could find no settings that where different to a default profile. I spent about 3 hours trying to track it down and finally found why the problem occurs. As you know I have some fairly heavy customisations. One of which is the M3/4/5 scripts. These scripts check for errors in starting the spindle and if an unrecoverable error occurs aborts execution of the rest of the script by using a M2. Here is a really simplified script showing the issue. Put this as your M3.gcode and when you load a gcode file no toolpaths will be displayed.

O<error1> if [#4100 NE 3]	(dlgname,Spindle Error, opt=1)
	(dlg,Failed to set spindle speed, typ=label, x=20, w=280, color=0xffa500)
	(dlg,Response size wrong, typ=label, x=20, w=280)
	(dlgshow)
	M2
O<error1> endif


M3

My guess is when parsing to generate the toolpath it sees the conditional M2 and stops parsing at that point.

O<error1> if [ACTIVE[] AND [#4100 NE 3]] ....

Thank you so much. After updating my scripts with this everything displays as it should!
