From 2015 until 2021, the GCode Sender was improved and acquired new features that were fully compatible with the CNC machines we manufacture. At the beginning of 2021 we started to build a new multi-axis software, GCode Sender 4-Axis, which replaced the "classic" GCode Sender and which we will fully support from now on.
The source code of the classic GCode Sender will remain available on GitHub for everyone who wants to see or use the code but unfortunately we will stop supporting it.
