Just upgraded from build 4300 to 4612 and a new PC. Importing the 4300  profile with a few minor tweaks got everything back in running order but my machine boundaries are not displayed on the toolpath screen as they were in build 4300. Soft limits are enabled and the Min and Max distances are also set. Is there some other setting to toggle on the machine boundaries?

If you go into the screen editor, select the toolpath, and then on the left side in the properties area there is a option to display the soft limits. You will need to do this for all toolpaths in your screen.

Bada Bing. It worked! Thanks Swifty, you da man!
