ioSender - a gcode sender for grblHAL and Grbl controllers

Please check out the Wiki for further details.

8-bit Arduino controllers needs Toggle DTR selected in order to reset the controller on connect. Behaviour may be erratic if not set.

Toggle DTR

If you want to test ioSender with grblHAL but do not have a board yet you can use the grblHAL simulator. Build it with the Web Builder, unpack the .exe-files in the downloaded .zip somewhere and open a command window (cmd or PowerShell) in the folder by <Shift>+Right clicking in it, select the Open PowerShell window here or Open command window here from the popup menu to open it. Then find your computers IP address by typing ipconfig - the IP address can be found in the report generated.
Run the simulator by typing ./grblHAL_sim -p 23 - 23 is the default Telnet port number and you may have to change it if a Telnet server is already running on the machine. Leave the window open.
Now start ioSender and select the Network tab in the sender connection dialog, change the port number if you run the simulator with a different port, type in your computers IP address and click Ok to connect.
You can run gcode programs, jog, access settings etc. but not use gcodes that needs input - e.g. probing.
The simulator can be stopped by typing <Ctrl>+C in the command window or by closing it.

Latest release is 2.0.44, see the changelog for details.
