Since my previous post I have managed to cure the 'Pausing' problem.
Everyone says to have CV Mode turned on, and everything else relating to CV turned off.
The problem (for me) was that with just CV on and everything off the machine rounds all sharp corners quite a lot.
I found the optimum settings for me were the following :-
CV Mode ON
All CV Related items turned off EXCEPT for CV Dist Tolerance which is set to the default 0.9
This along with slowing the acelleration down to 200 has made my machine do perfect Pen Traces
I will post some sample cuts very soon!
