Is there a simple way to not need to log into my cnc machine? Actually,  is it possible to have linuxcnc fire up automatically too? I want to flip the breaker on my machine and then hit a power on contactor for the servos and be ready to machine. No time to be typing in passwords to drill a hole.   lol

Now that my machine is mostly configured and ive got all the software in it, its not gonna be going online ever again. 

This is probably simple but I can't find it through some searching.
My machine is set up as imperial but I do (basically all) my gcode in metric.
As a result, when AXIS starts it comes up in inches, and I have to change it to metric before touching off tools.  Similarly, the cylinder that represents a tool displays in inches so when I change to mm it's 25 times larger than the job and I can't see anything.
I'm using linuxcnc 2.7.14 and would appreciate any advice.
 

Well it should be a drop-in replacement, I'll take al ook tomorrow. 

I had no knowledge about CNCs, but over the last year I have learnt how to use Linuxcnc with a mesa board for my DIY lathe. Would like to dive deeper into knowing about HAL, Macros, O-codes, and maybe those custom Virtual panels that I see all over the internet. Now the thing is, what do i need to have prior knowledge about before diving deeper into this stuff? Python. Thanks in advance.
