You need a Logic Level Converter (https://www.sparkfun.com/products/12009).  ;)
But I'm not sure that it will works with PWM signal pin.  :P

I assume all pin of both chip will be connected to each other right?
D1 of Nano connected to D1 of Mini Mega and so on except only Vcc pin.
If you power on the Mega and set pin D1 to hight then +5v will apply to D1 of the Nano and it will be fired even nano isnt powered on.


Sorry if I get you wrong.  :)

I'd like to build an controller shield that sit on top of mega 2560 like the RAMP board :)
It'll be made specifically to laser machine :)

Github is a powerful tools.  ;)
All changes they made from gnea/grbl are merged.  ;D

I'm planned to create my custom controller board as well as my machine's structure. It's all DIY.
I want to add jog keys, e-stop, homming, weak laser mode switch and wireless communication.


My experiment:
-with grbl 1.1d + 328P UNO (clone) and FTDI chip: the stepper motor move like when you accelerate a car or motorcycle (speed gradual increase/decrease till reach target; I don't know how to explain please excuse my English
-with grbl 1.1d + mega2560 (clone) and CH340 chip: stepper motor move in steady speed.


But I just break my Rx0 serial pin of my mega2560 as used as a programmer to burn ESP8266 firmware.
Breaking somethings is a part of fun of building somethings.


ps. I'll write my own software as well. Coding is easy you can find the sample code on the internet. But the hard part is design the gui.
You need to think like you are user. The flow of using your software and how convention to use your software.
Why do I care? Because I plan to release it as an opensource.  ;)
If you can't write the code don't worry I'll write it for you but at lease you build it yourself (hint: Do It Yourself).


Have a good day to all!  ;D

Its not very likely to see Grbl ported to ESP8266, it has too limited GPIO available and likely not support the precise timing possible with the ATMeaga which does not run things like WiFi as a background process making timing unpredictable.


And it's an ARM cpu architecture the grbl needs rewrite from scratch.  ::)

@Lob thanks for the info  ;)

I'm not sure porting grbl to ESP8266 is possible. c/c++ is a headache job let me try... :P
But it more easier just add esp8266 to serial port of arduino.
imagine...wiring arduino's serial pin to esp8266's pin...done.  ;D

Definitely interested, I have a Mini-Mega adapter to L7 board that really needs a 1.1d build. I have been playing with it and getting no place.

First build successful. Now to change some options!

A couple of questions Did you increase segment buffers or Block buffers in the code or should I use the override settings in config.h?


Thank You


I'm sorry Lob, I've no idea about segment or block buffer, to answer you No I've not change any code except cpu_map.h and some relevance files.
May I ask what is the benefit of increasing it?

Another idea popped up in my head,



I've some ESP8266 laying around for my smart home project.
It has an AP mode, Station mode and wifi-direct mode.
It can be programmed to listening connection via tcp/ip and write an output to its serial pins.
It also have digital/pwm pin like an arduino we can use these pins as a phicical jog, e-stop or homing button like...
 when digitalPin 3 = hight then write "G00X0Y0Z0" or whatever command that grbl supported.
And it support arduino sketch we can write code like it is a regular arduino.  :)
But not sure about connection speed. ???

For anyone who interested in grbl 1.1d on mega2560 I publish to my github here https://github.com/parnz/grbl-mega2560


Disclaimer: I not responsible to any damage to your car, your house your girlfriend , your...whatever. Use it at your own risk.

it alright i'll will implement it in my own software just for fun  ;D

T2 Software Updates / Re: Updates

I have not installed "I" as yet, I always have to uninstall then reinstall T2. It will not install over the older version for me.
Same here. just install 1.3i recently.

T2Laser has always had a simulation "view", it's in the laser control screen. Click "View" in upper right of G-code window, you can see what is going to be output and also run the code at various speeds. Now it even works with velocity mode where speed is used for the grey scale control instead of laser power.


No Zax I mean a small dot moving relatively to the laser head while sending gcode.  :)
The "view" you mentioned actually is the "preview" of the output.

I'm think about the wireless jogging joystick project.... ;D
