You seem to know Mach4 a lot better than me.
Answer me this if you can(or anyone if they know). In Mach 3 I could "feed hold" and then use the jog key to adjust the spindle , even change the work coordinates on the fly during the "feed hold".
For example, I would do this during feed hold to fine tune say my Z Zero height half way though a tool path run.
In Mach 4 I simply can't do anything once I click "feed hold" at all. I can't jog etc(Yes keyboard jog is enabled) let alone adjust the work coordinates during the feed hold. Possibly mach3 was never supposed to work that way and my older version just did? With Mach4 I have to hit stop, which seem to work, but I do think I may lose a step or two verse using feed hold doing that.
Is this a Mach4 thing or some setting I don't have set up in Mach4?
