Hi There…
We have a positioning machine that uses linuxcnc that we want to better
automate the restart procedure. Is it possible to script in the initial file
for the system to switch to Machine ON (as long as there are no active limit
switches).
This machine is inaccessible to humans without turning off power, so there is
no safety concern.
Thanks so much,

All of my machines are power controlled 100% by the state of the F2 key,
by shipping its state out to a breakout pin or 2, which in turn trigger
a block of 60 amp 600 volt SSR's that control all power to the machine.
By the same idea, any error reported by these new stepper/servo's knocks
F2 down from the e-stop circuit that signal is coupled to.
Since these stepper/servo closed loop drivers need a power down cycle to
recover, this is the first step in recovery from an error.
Fix the cause of the error like a wrench left on the table or??? remove
the tool or not depending on how it moves to home because it will need
rehomed, hit f2 to repower the machine, rehome it and either hit run to
carve air, or if feasible, run from line after reinstalling the tool if
it was removed to home it safely.
