why doesn´t function G64 on chilipeppr?

What does G64 do? And do you mean why does your CNC controller not support G64?

the machine slows down after every line by milling a curve or text

G64 means not to break down the voreward speed between the milling lines

Well that would be your cnc controller that implements that, not chilipeppr.

it is a TinyG v8

Maybe best to post to their forum on google+ or on their website.
