General Mach Discussion / Re: Spindle runs in Parallel mode OK but not in ESS ?

Definitely was set to step/direction, yes I agree that it doesn`t show in the XML file in the ESS section, the setting for the pulse width is there, showing as 5us, all the other settings are as I did them.

Looking like the ESS plugin may not be transferring that setting to the XML file and/or loading it to the ESS card, a "bug" maybe

Thinking about what you said I suppose it is external in a way, as I see it the ESS takes the Mach3 "numbers" ie axis motors, coolant and spindle etc so looking at the system that way then the control will be from the ESS motion control card and not actually from Mach.

Did that make sense Did when I typed but not when I re-read it

I thought you were controlling the spindle speed from Mach but looks like you must be doing it externally, is that correct?
Hood

Not as far as I am aware, all speed commands are done in Mach and step pulses are output from Pin 1 via a straight "pass through" BOB to a step pulse to analog 0~10 volts output converter and the 0~10 Volts are fed to the input of the DC Drive unit, that`s all there is.

Update :-

Today I got some work done and also tried a couple of things but nothing changed, still the same issue, everything will run fine at spindle speeds of 2200rpm and below.

Even tried a different PC with a different version of Mach3 and a different Smoothstepper Plugin, I didn`t transfer the XML file from the original PC, instead I opted to do the new one from scratch, still exactly the same.

As for "noise" issues, I even got an old mains drill that the brushes are shot on and ran it inside the mani cabinet with all the electronics, it is so bad that at around 5~6ft from a radio it blanks the radio, didn`t make any difference, should have sent everything haywire in my mind.

I did start with the lowest value of 1.43, was thinking of working my way up a level at a time in multiples of the base 1.43, if I get time I`ll try another step today  

Thanks again for your input, much appreciated

OK, I did try changing the pulse width from 5us to 3us, didn`t make a difference.

Also tried putting a value in the E Stop noise filter, now it got really weird

Spindle would now run at the full max speed of 4000rpm without tripping out, however the E Stop still did, it stopped the axis movement but not the spindle, that just kept running, Mach reset button flashing as it should (Now here is the weird bit) but when pressed the spindle then stops

Not had time to try anything else today, trying to get work out

it could be that the spindle produces more noise (electrical) at higher revs.
Hood

I agree, could be possible, the spindle is after all a DC Brushed Servo motor so will be producing some electrical "noise" for sure, why it would manifest itself at that specific point is a mystery though.

I won`t make any of the suggested mods on the PC that is running the machine, right now I have to get some work out the door, I do however have another PC that I have fitted with a new SSD drive and a new clean install of XP Pro, there is nothing elese on the PC only Mach3 with the ESS plugin and the "Configurator" software so I`ll make my changes there and use it for testing

Could also just be noise tripping the ESS, you may want to set a small value in the ESS plugin for the E-Stop filtering.
Hood

Thanks, I`ll have a look at that as well, it is a possibility although the "tipping point" is very specific, spindle will run all day at 2200rpm, at 2250rpm it will go into E stop condition in around 15 minutes run time
