I am trying to build myself a 3 axis cnc router and I was wondering if some more professional routers could check what they're doing.
For example: if I tell the machine to move 12cm on x-axis , a component to check if the machine really moved 12.000cm on x-axis.
I hope you understand what I mean...a device that prevents ruining your model due to backlash or any kind of problems.
If it exists such thing, what is the name of that device/component and where can I find it.
If not, don't be to harsh...I'm new here
