It has only one thermocouple input, so I'm not sure how you'd control
the second extruder head temperature.
Being an Arduino, it does have half a dozen analog inputs for

This article is almost 4 years old but it's got some good hints about
fast booting. http://lwn.net/Articles/299483/
It points out a cool tool name BootChart
Not LinuxCNC specific, and going from the top of my head (it's been a long
time since I hacked away at Linux kernel) -- booting in 3 seconds is a bit
tough to do, even with SSD -- but the key thing is to strip as many
services and dynamically loaded device drivers. If you can get the kernel
image
Oh, and one more thing -- I believe there is a kernel argument that you can
pass to have console logging turned off. That can improve load time as
well. I'm not sure what your definition of headless is, so I'm not sure
how much this plays into your situtation.

BTW, why 3 seconds? It might help to know what you're trying to achieve -
is it a device safety issue, or more of a usability thing?

Greetings;
Yesterday I did the threads, 1/4-28, .200 long in that nipple, this time
making it out of an inch of 1/2 grade 8 bolt. That code has a relatively
huge leadin, .4 before the thread starts, so that end of it was absolutely
no problem. I raised the spindle speed from 200 to 250 revs
One more:
