    How to set a negative value in THC Min (Mach3)

    Hi Everyone,

    Does anybody know how to set a negative value in THC Min. THC Max is not a problem because I don't need a plus sign in front.

    However for THC Min, I type in a value with a negative sign in front but when I press enter there's no negative sign so I'm assuming Mach looks at it as a positive value.

    Thanks,

    Keith.

    If you are using the latest screen set (circa 1/8/11 or later) then the THC MIn setting in the Settings tab was not made wide enough in the screen set and does not display the "-" sign on the left. It's there and the value is stored correctly in MACH. I am going to do a minor screen update of that screen set (just make the DRO's one character wider) and put it up on the CandCNCSupport Yahoo forum.

    I gave you a quick fix (manually edit the XML file) on the forum but then realized you don't really need to do that since it's a display issue not a settings issue.

    Hi Tom,

    I just sent you a reply on the Candcnc Yahoo group, pretty much saying that's what I found. I often post on CNCzone too due to the time differences between the US and Australia, in the hope I may get an answer to my problem on the same day.

    Once again thanks for the prompt support.

    Keith.
