I want to sell our machine to the end user, this machine uses Mach3 as control system, a question is :
it is easy to change a parameter for the end user,  while a mistaken can cause damage, so I want to only show the set up screen to our technic stuff, he can change the parameters by entering a password, but the controls in the screen will be invalid if he has no the pass word.
if any body can help me thank you~~~~~

That is exactly what this plugin was written for:

http://www.machsupport.com/forum/index.php/topic,12239.0.html

it allows OEM control at 3 different access levels, and includes access levels to screens as well. Read both post, and download and play with the sample one.

Will lic. per machine, or one time purchase, your choice, email me at: poppabear"AT"hughes"DOT"net
