This NanoDLP version adds Z_move_comp report string to the dwell commad (G4 Pxx) enabling the automatic sync of NanoDLP using the command [[WaitForDoneMessage]];
The way to use this is to send a dwell command after the Z motion commands, the dwell only runs on the microprocessor after all the other commands have been executed and will return a serial string Z_move_comp that NanoDLP is waiting for with [[WaitForDoneMessage]]; command.
This version is forked from the SolidRay project (that is forked from the original grbl0.9j)

- IMPORTANT INFO WHEN UPGRADING TO GRBL v0.9 :
- Baudrate is now 115200 (Up from 9600).
- Homing cycle updated. Located based on switch trigger, rather than release point.
- Variable spindle is now enabled by default. Z-limit(D12) and spindle enable(D11) have switched to access the hardware PWM on D11. Homing will not work if you do not re-wire your Z-limit switch to D12.
Grbl is an open-source project and fueled by the free-time of our intrepid administrators and altruistic users. If you'd like to donate, all proceeds will be used to help fund supporting hardware and testing equipment. Thank you!
Grbl is a no-compromise, high performance, low cost alternative to parallel-port-based motion control for CNC milling. It will run on a vanilla Arduino (Duemillanove/Uno) as long as it sports an Atmega 328.
The controller is written in highly optimized C utilizing every clever feature of the AVR-chips to achieve precise timing and asynchronous operation. It is able to maintain up to 30kHz of stable, jitter free control pulses.
It accepts standards-compliant g-code and has been tested with the output of several CAM tools with no problems. Arcs, circles and helical motion are fully supported, as well as, all other primary g-code commands. Macro functions, variables, and most canned cycles are not supported, but we think GUIs can do a much better job at translating them into straight g-code anyhow.
Grbl includes full acceleration management with look ahead. That means the controller will look up to 18 motions into the future and plan its velocities ahead to deliver smooth acceleration and jerk-free cornering.
