MatterControl filters G-Code as it sends it to the printer via serial USB communication to maintain compatibility with a large range of printer types.
Automatic Changes
M190
M190 commands are automatically converted to M109 commands.
M140
M140 commands are automatically converted to M104 commands...
G91
MatterControl accepts commands for relative positioning, but instead of just allowing them straight through it interprets them as absolute coordinates and feeds those to the printer.
G0
Certain printers do not accept G0 as a valid command for movement, so MatterControl sends the more common G1 command instead.
Version 1.6 will have a new setting which will allow G0 commands if desired.
Coordinate Truncation
To save bandwidth, MatterControl truncates superfluous coordinates in movement commands. For example, if the printer is currently at coordinates X30 Y40 Z50 and the next G-Code command is:
G1 X30 Y70 Z50
then MatterControl will truncate this command to:
G1 Y70
since the X and Z coordinates are the same as the current position.
