Mach3 how do you set thc to a negative value?

Post by PlayingDirtyRacing »

I just spent the past couple hours searching for an answer. How do you set the thc minimum to a negative value? I have the proma thc, and it absolutely will not go below 0.000 inch. It functions perfectly besides this. I have tried numerous different times to set the minimum thc to a negative number. Mach3 just will not allow me to put the negative symbol on the line. I watched some videos and tried to enter the value exactly as shown. But still no luck. Am I missing something here?
Can someone please give me a step by step process on how to do this. It is really bothering me.
Any help will be greatly appreciated, I am not real good with computers, but can normally figure stuff out with the Internet and you tube. But this one has me stumped.
Thank you.

There is no proc4ess if the screen set they provided or that you are using won't take a negative number into the OEM DRO . You set in the screen painter what size and type numbers it will take. The THC Min and MAX values are added to the screen set and the values stored in the XML file.

The vendor that supplies you the custom screens and/or Profile (XML) for their products should be able to help you. If not you may want to rethink your choice of vendors.
