DDCSV2.1 additional functionality

Lukasz

Hello,

Some time ago I bough my DDCSV2.1 cnc controller and I see that there is a lot of great features which are not documentet anywhere. Therefore I have a few questions:
- is there any full list of variables that can be used in custom scripts? Like those used in "slib.nc", for example
#1=#451
#2=#452
#3=#453

- what are "T.nc", "1.nc", "2.nc", "3.nc" ... files responsible for?

- is there any documentation for MPG serial port protocol (TX, RX lines) and usage?

- is it possible to add manual tool change request on the screen in future version of the firmware?
For example if T2M06 gcode is executed then display information / small window on the screen "Please change tool to Tool 2" or somethink simmilar.

- is it possible to add in new firmware a Gcode viewer (to see text content of the selected file)?

- where to get the latest version of the firmware?

Thanks for your support

Regards
Lukasz
