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

I have heard that the latest couple of versions had bugs. Don't remember though what version I have on this lathe. Was just at the machine, but forgot to check. will check tomorrow.

I soldered in an optocoupler on the Step/Dir line between the ESS and the Ultra 3000 and another one for the Index going back to ESS. These are the only two lines sharing same ground with the ESS. Thus I was able to use a separate power supply for the ESS. The immediate result I noticed is that moving the Servo power connector had absolutely no effect. Before that, when I moved the connector up/down the GND pin would disengage and the axes (steppers) start moving at a steady feed. I think it comes to show that now I have the wiring done properly with good isolation and it will save me more possible headaches in the future. Besides, I did suspect it was losing a step every now and then, but couldn't confirm this. Hopefully this got solved with this move as well.

haven't yet fully tested and run a program. Replaced two double channel optos, but on both the second channel didn't work so the direction line was not working. have some more spares, so hopefully will find a owrking one tomorrow. Also, was not able to get the Index line through the opto. Will use a scope tomorrow to check this too.

Thanks Hood. Swapped the Ultra 5000 for a 3000, so using Step/Dir now Wink
