Hello,

Problem is not resolved ... But I have one more issue to check .. this evening .... :)

My motors acts like - http://www.woodworkforums.com/showthread.php?t=167883
( only on 200 .. 300 mm of movement .. not on every rotation .. )

I have XP optimisation.txt file with step by step guide how to setup PC before Mach3 installation ... but maybe I miss this step for switching to standard PC .... and this cause this signal spikes on LPT - missing steps and stalling for small periods ...

So, I will check and if this is a problem will post the results .....

I have 2 core CPU and I hope switching to Standard PC ... will fix the problem ....

THANKS TO ALL OF YOU !!!

Emil
