- Add option to use Timer1 or Timer3 library which allows you to use GRBL/UNO or RAMPS/MEGA HW.
- Add optional Z axis.
- Use fastio to speed up the code.
- Add more Gcode commands.
- Make all axis 32bit to allow work on big machines.

Positions should be modal; that is, if I don't specify an X coordinate in a command, the default should be the current/previous X coordinate, rather than 0.

It is modal, it you look at the execution of the task it is treated to support relative/absolute positions.
Setting the values at the first parsing of the buffer leads to multiple conflicts. It was hard to troubleshoot , cause when you send the commands one by one there is no effect. When running a gcode file is that the conflicts get afloat.

You're right that this works for relative, but there perhaps should be a conditional here. The new code treats "G1 X555" as "G1 X555 Y0 Z0," which is correct for relative positioning but is not correct for absolute positioning.
