Hi, would anyone be able to help me in making a Auto tool change lua script for mach4 as in ihave no idea what I'm doing  
I have a cmsio s controller with HSD spindle with a dust cover to auto lift, my tool rack is made to lift out from under the table .

so what I need to have happen when a tool change is triggered

tool change activated , lift dust cover (ouput trigger) , lift tool rack up(output trigger) , put current tool away , get new tool , drop tool rack down , drop dust cover down , continue with job

wish I could do this myself just not my area and would really appreciate if some could help me out

thanks
Sean

have a look in the C:\Mach4Hobby\LuaExamples folder

ok, then?

each step you said (like lift dust cover) i think have sensor to confirm ,action done(or not) then you also must consider that sensor in other
action(like homing)
you also need decied what do if one of every each action didnt compleate
then you have 2 sensors inside spindle
what i mean to say its not "help" if you have specific question im sure this forum its correct place
but script like this ,can take whole day(including testing, and as i described give solution for any unplan situation)
if you want save money ,try read the manual ,there basic ATC script
good luck
