ART,
I love it when a plug in works first time tried!
This is using Mach version .028
Here are screen shots at 115 and 402 rpm.
Even though the lathe screen DRO flickers by 1 rpm in both 115 and 402, the advanced diagnostics is showing the slot based rpm to be greater by percentages which relate to the threading tests that were done ( ref my reply #488) .
So for 115 rpm .9 rpm such that .9/115=.0078 ( .8% change in lead )
During the 115 threading dry run the rpm for threading to the thread based rpm only changed by only .01.
So for 402 rpm 1.27 rpm such that 1.27/402=.0032 (.3% change in lead which very close to the .0035 lead error) and somewhat confirming the testing.
Maybe you have found were the rat was feeding and it's about to get a dose of poison!
Question / confirm?
If i do actual thread testing, then I'll need to have the Advanced Threading checked / Enabled and it will modfy the threading cycle appropriately?
