This configuration file should work as a base for Anet A8 printers
using the stock Anet v1.0-1.5 boards from late 2016-2017, which are
based around the AVR atmega1284p. Minor tweaks may be required to such
things as /dev/serial/by-id/, thermistor sensor types, and offsets for
carriage and bed.

Added the pwm_cycle_time option for heater config sections. Defaults
to previous value of 0.100 seconds, but may be reduced to shorter times
at the expense of MCU workload and possible MOSFET heating, depending on
controller design. Some printers that need bed PID to be enabled,
notably the Felixprinters series, are known to benefit from shorter
cycle times, as the default 10hz rate results in excessive voltage
supply droop.
While this option can be used on extruder heaters as well, there
is not expected to be any particular benefit from doing so unless
the extruder heater presents a particularly large load.

On a delta printer, z moves require the mcu to support the greatest

Change the config file so the maximum accel and velocity are specified
in the "printer" section instead of the individual "stepper" sections.
The underlying code limits the velocity and accel of the toolhead

Invert the default meaning of the stepper direction pin. Instead of
treating a low value as position motion, treat a high value as
positive motion. This matches what other firmwares do, and it matches
what common stepper motor drivers document.

A pullup setting on an input pin (ie, '^') should enable the hardware
pullup resistor, but it should not invert the trigger level (ie, it
should remain trigger on high). Those that need to change the trigger
level (ie, trigger on low) must now do that explicitly (ie, '^!').
This makes the code match what other firmwares do.
