I bring to your attention my version of the control panel for CNC. It can work not only with pathpilot but also with linuxcnc and mach4. The data exchange protocol is modbus rtu and modbus tcp/ip. It can be wired or switch to wireless mode (internet is not needed). For pathpilot requires minor changes to the python file. Screen 3.5 or 4 inches. More details can be found on the website http://www.tftpendant.ho.ua/ I would like to know the opinion of the respected community. What changes can be made to make it more convenient to work.
