when I press the setup button on  the cutter it says the baud rate of 9600 but what is the E speed +0 vale  for/do ?

Listed yes and thats it. Acutally just shows a pic and says e speed +5 vale and thats it.

Whats it do ? Its purpose in life ?

Is that the default ?  +5 cuz mine says +0

No mention of it otherwise in the manual.
