PiDiCNC Control System

That is a older beter quality common PC with ATI integrated graphic card.
I will do the same test on a Asus P5B Deluxe with core2quad tonight to see if it makes any difference, as for software they both run LinuxMint 18.1 , HP with 32bit RTAI and Asus with 64bit RT-Preempt.
Will also check how it does on an i5 2.53GHz dual core DELL laptop with Intel AND Nvidia graphic cards running 64bit Mint 17.3.
I can also try Ubuntu 10.04 and Debian Wheezy, but i doubt it makes any diference.
Regards,

Just to try to get more info about why it slows down so much after a certain line count, it should not as 150.000 lines of code are a bit over 2 MB , so should pose no such problem.

That is the same gcode file running on an Atom @600MHz ?????
Well that warants a bit more testing for sure. Stay tuned.

Ah OK, still that looks as it is running nicely, and that is a much slower computer overal than the one i tested on, soooo that is pointing towards the graphic driver issue........hmmmm, oh well on to more testing.....just as soon as i finish this esspreso!

Some results:
Same computer 2X 2.5GHz AMD with ATI graphic card, 3GB RAM etc, ngc file with 146603 lines of code >
Ubuntu 10.04 Linuxcnc ISO, opens and runs without any problem, Linuxcnc GUI responds normaly, screen refresh OK, drawing on screen following tool path OK, computer usable with no signs of slowing down.
Ubuntu 12.04 with RTAI 3.4.9, when opening that file it becomes completely unusable, even computer overall slows down to unusable level.
Could not test Debian Wheezy as the USB it is on decided to give up the ghosts. Will do a new USB and test tomorrow.
Did not test on other machines as running on 10.04 just made it interesting.
All systems except 10.04 have Linuxcnc version 2.8, 10.04 has 2.5.4. All things point now to the new trajectory planer as it has a much biger look ahead for the gcode. If that proves to be the case, if i remeber correctly, that can be lowered, so it would be an easy solution.
