I don't mean to resurrect such a long dead post, but i found a solution to a problem and want to post it in case anyone else has the same problem.  Perhaps in a few years, someone will be running google searches and come across this thread like i did.

i have been plagued with this random "estop requested" error for quite awhile.  Yesterday it pissed me off enough that i devoted half the day to fixing it.

I'm running mach3 with an ethernet smoothstepper, on a windows 7 machine on a G0704 conversion.  I had tried ferrite beads all over pretty much everything (did nothing to help).  I rerouted wires to keep high voltage away from low voltage wires (didn't work either).  I set my various debounce settings in the smoothstepper plugin to as high as 200,000 (no effect whatsoever).

It started working fine after i deleted mach3 version 3.043.066 and installed version 3.043.062. 

Suddenly, mysteriously, in the exact same machine with the same wiring, Mach 3 version 3.043.062 cured the random estop triggering. 

My clue that it was a software issue and not a hardware issue was that it, in a 30,000 line program, it kept triggering the estop, on the exact same line of code. Every single time.  I could reset the Estop, and "run from here", continuing from the same line of code and finish the program fine.  but on many programs, it would trigger the estop, on the exact same line of code every single time i ran the program.  Yesterday i ran the same program 10 times, and got the estop on that same line of code ( x 2.3, Y1.125, z-.125)  Thats it, just a simple linear interpolation line amongst thousands of similar lines.  but it estopped on that same line, every single time.

Thank you Bryanna,

That is an excellent guide, very easy to follow.

Great, thank you Steve.

Ill try your suggestions in the morning.

Mach4 General Discussion / Mach 4 demo?

I tried searching, but can't find the answers to my question in previous threads.

Ive been using Mach3 for years, and have been considering getting a Mach 4 license. I prefer the look of the Mach 4 gui, it seems a better fit for my mill and Warp 9 seems yo put more effort into the Mach 4 plugin.

I downloaded Mach 4 to try in demo mode, but absolutely nothing works.

The software installed fine, and starts fine, but all i can do is browse the various screens.

It doesng seem to recognize my smoothsteppers existence, i cant access the ess plugin, it won't run g-code.  Basically, all i can do is see what the gui looks like.

Am i doing something wrong? Im definitely not paying $200 for the license until im certain it will run on my machines integral pc motherboard and cnc hardware.

Thanks. Ill try that.

There doesnt appear to be a way to edit previous posts here.

I've been trying to open the ess plugin in mach 3 to familiarize myself with the setup screens, but it doesnt want to open without having the ess connected. 

Is there a way?

I didn't confirm it via email, but i found multiple references to its existence from different sources, including some instructions on setting it up.  It only available in PWM mode, which is what my analog converter uses.

well it sounds like your installation with the USS is working fine.

I think the principle determinant is whether the USB communication is adequate. There have been a few users whom have no end of trouble
with 'running out of data'  and total cessation of USB comms. It sounds if your 'electrical noise' environment is reasonably benign. That being the
case then carry on with the USB.

From your description the only feature you will really miss is the spindle  PID.

It would be possible to make a small circuit board that would add that feature....if you are into electronics. I mean not so many years ago ALL
speed control was done with analogue boards.


I took your advice. An ethernet smoothstepper is in the mail.

After reading up on them both, i definitely want the backlash comp and PID spindle.

I ordered a mini pci-e ethernet card, which plugs into the pci-e slot and will give me an internal ethernet header, keeping all the wiring neat and clean (and noise free).

Thanks for the info Craig.

I lke a noise free case, i shield, use lots of twisted pairs and have a fetish for ferrite beads. I donte have any trouble with noise.

The USS is running great, your correct that ill only miss the pid. But, maybe not that much.

I just played with some 6061 using MDI.  Without pid, running at 3300rpm and 16ipm with a .375" 3 flute alu-power, i had no loss of speed using .186" stepover @ .05" doc.  I had a 10rpm loss of speed @ .375 stepover .05" doc, and a 40rpm loss of speed with a .375" stepove and .1" doc.  All running at 16ipm.

I can live with the open loop spindle.  Hell, the spindle runs smoother anyway under the smoothstepper than with pid, on the parallel port.

"Do you prefer wiring neatness or do you prefer a reliable, working CNC solution?"

Without the smoothstepper, i have exactly that.

Ill consider what yove said. I have the USB smoothstepper installed and currently running a program to test it.  Everything is running very well except as predicted, the spindle speed accuracy has suffered as it is completely open loop.  It is within 40rpm though.  Everything else is great.

Ill try cutting some metal in a few minutes to see how much it bogs down the bldc motor without a pid loop.  If its too much, i can just unplug the smoothstepper and plug the parallel port back in.

The parrallel port has been running like a champ since 2014, i just thought it would be nice to run 64bit windows since my controller pc has a 64bit cpu and memory.

Im sure i could sell the USB smoothstepper on ebay and come up with a way to route the ethernet cable out and plug it into the i/o panel, that doesn't look line Fred Sanford did it.
