I just installed version .067, but I got the same behavior. I did some more tests.
If I switch Mach to Lathe, with OEM buttton 131, the TOOLDESC label and the DRO 246 works correct. Tool selection with DRO 824.
If I switch back to Mill, the TOOLDESC label keeps the last description selected during Lathe mode. Tool selection with DRO 824
If I start Mach (Mill function) tool 0 is selected and so i see the "Empty" description.
Is here maybe a bug?
Thanks for checking.
