I am thinking it's PC dependent. Wonder though if there're any network settings I could change in Windows to sort this.

Was still experiencing those annoying runs out of data (controller now at 500Hz). So tried the plugin you posted. This introduced a new problem: every time I used a run from here - as soon as the OK on the prep move window hit - a SmoothStepper Watch Dog window popped up! It suggests increasing the trigger time, but that is already set to the highest 3.1 sec. Wasted a few hours and haven't made a single part yet! Can't get from start to end without a ESS error!

And an update about threading: ran several tens of thread cut tests today with the index being halved in the Smooth Stepper config and good news is that as long as I don't disable the spindle servo and rotate the chuck manually, it seems to pick up correctly each time, running same thread over and over again.

Anyhow it's sad as the lathe is useless since can't make a part without getting an error from the ESS.

Same here. Don't want any development, just want the bugs fixed. And you are right about Turn Sad

Normally I would really delve into the issues and try and isolate exactly where the issue lies so that Brian has an easier job tracking things down. However as Brian didnt show any interest in a previous issues I have recently reported then I have decided not to waste my time looking and just return to an older version.

This is the sad part. They seem to be not interested anymore in providing support for Mach3. I feel like being forced to move to Mach4 (assuming it will eventually show up) - and not from my free will or choice. That's a shame considering there are only a handful of bugs that if were removed could make Mach3 a perfect program.

Thanks for the encouragement, Hood. Still more like a shot in the dark, but I will give it a go when time permits and if factory defaults fails.

Yes! Exactly!

Ah... it does look like a hardware issue. Not sure if I would be willing to take it apart though. Haven't yet tried resetting factory defaults. Will try that first. Mean time it's divided in the ESS config as it used to be.

Ran a a couple of short programs a few tens of times each. Had the ESS running out of data once at 4Mhz controller frequency. Reduced it to 2Khz and so far it looks good. Using the current plugin (ESS_v10h2d1a) and Mach version .062. It's hard to tell though if the problem has gone. Only time will tell. Haven't tried your plugin since I want to know what exactly solves this. If I see the problem again I will try your plugin.

Mach3 .062 has a strange issue however. If I feedhold and then start again it would make unpredictable moves at rapid feed for a few seconds (just skipping all over the place with the toolpath showing exactly what it does) and then follow remaining toolpath correctly.

OK. Didn't think about resetting to factory defaults. May be worth a try indeed. No line driver - using a scope right on the drive's connector.

This is what I have been doing - either under pulley setup or in the ESS config. Problem is that I found that I couldn't re-ran the same thread. It doesn't always pick up the index in the same position of the chuck. Thought if it would be done in the drive it might be different.

Got  the direction line working today. Turns out I was connecting the second channel of the opto with wrong polarity Grin Now it works fine. Don't know if it's my imagination but I think the steppers got a smoother mid-band sound with this isolation.

Also partially got the index signal sorted. I am getting it through the opto and it works fine. But I am using the unbuffered output from the Ultra 3000. Now I wanted to use the buffered one so that I can divide the counts inside the drive (hopefully it divides the index too), since I have a 2:1 reduction. However there is some strange problem with the buffered Index line - it outputs exactly 8Khz signal at all times - even when the motor is still. A and B buffered outputs are fine, it's just the Index that does this weirdness. Looks like a bad drive, though it is a new one. Will probably have to use an external opto-sensor for the Index Sad
