Robert has been working very hard on the new TP. Here is an example This program I found on the internet. (small line segments) http://electronicsam.com/images/KandT/testing/internet.ngc
533228 line program running G64P.005 Old TP 2:37:42 New TP 1:38:49 Quite an improvement!! The spiral.ngc program now starts at almost 400 ipm vs 110 ipm currently. There are some issues to work out yet - but as little time it has taken Robert to get this far - I don't think it will take long to get to a beta..
