Problems with mach3 and cslabs controller - jittering & losing connection frequently.

[Stressedwoodman]

I know I haven’t posted for a while, but my machine has been working fine, and life has been busy.
I have a developing problem, sometimes the machine jitters like it’s catching up with data, other times more commonly mach3 loses connection with cslabs and it stops mid cut. I am using stepper motors. The jittering occurs on large complex 3d NC programs, mach3 losing connection is random when it occurs.

I am using a windows xp laptop and connecting via an Ethernet cat 6 cable. At first I thought it was the Ethernet ports - poor connections. So I replaced my interfaces with the machine with screw down Ethernet connects made by Neutrik for microphones etc, also a new cable which is shielded ( last on was to) The problem hasn’t gone away.

I cannot seen to find much information online about setting to tweak. Most popular suggestion was to use cslabs interface instead of mach 3.
I have rebooted my laptop a few times and cleaned all the contacts in the data path, so I am now not sure what to look at next. I haven’t changed any of the settings from those Dean helped me put in 9 years ago.
Any tips to resolve this would be appreciated

I have replaced my laptop with a Durabook - installed the same OS as before, but upgraded the CS labs firmware. Fingers crossed it seems to have fixed the issues. The new laptop has faster processors too, which may help, not convinced. Will do a few small jobs to confirm it’s behaving, before I am brave enough to start machining a walnut slab that I cannot afford to have any mis cuts on.
