- Limit pin internal pull-resistors now enabled. Normal high operation. This will be the standard going forward. - Updated all of the 'double' variable types to 'float' to reflect what happens when compiled for the Arduino. Also done for compatibility reasons to @jgeisler0303 's Grbl simulator code. - G-code parser will now ignore 'E' exponent values, since they are reserved g-code characters for some machines. Thanks @csdexter! - The read_double() function was re-written and optimized for use in Grbl. The strtod() avr lib was removed.
