Hi Thomas,
yeah those numbers would work too. I am beginning to think that OP doesn't have an ESS at all but one of those HM4...whatevers and it can't keep up.
There may be a set of parameters which would work, I suspect you'd lose a lot of resolution though. Seems a bit silly to spend big bucks getting a 1hp
servo and a good one at that, way better than the cheap run of the mill Chinese crap servos, only to get a Chinese control board that 'couldn't pull the skin off a
rice pudding'.

Hello Craig,

you are right that a couple of different parameter Setting should work.
and one ore the other would have some disadvantage.

but at the Moment stage (1 or 2 rev per min), ther must be an other
basic issue to restrain the Motor to spin in a expeted rpm.

anything is possible, just try it.
if you find some mistakes, in my bad bavarian english,they are yours.

Hi Thomas,
the key to understanding was OPs last post where he described the servo speeding up as he increased the 'steps per' but up to a 'ceiling'.

That tells me that the controller/BoB is not signaling or capable of signaling at a respectable rate. My set of figures requires 114kHz pulse rate and I suspect
his controller is maxing out at around 25kHz. A genuine ESS can go to 4MHz!

so the quick and easy check would be to hook a oszilloscope to the puls Input of the Controller.

Hi there

Well Craig, you are pointing at an interesting issue here, attached is a picture of my Motion card, and there isn't any other BOB involved

in my system, all I have is a lap top with Win7, an ADAA - B2 Driver, 750 delta motor, Motion Card HM-LAN-4axis - and a 24 V, 10 Amp Power supply, and the ac power to my Motor.

also how about my LAN Card and/or it's settings in my Lap Top? Do I need to do some settings in my Mach3

Regards

Hi,
that is not an Ethernet SmoothStepper, its a Chinese made motion controller and they've put that name on the outside to suggest similarity with a genuine
Ethernet SmoothStepper by Warp9 Technical Design.

Do you have any documentation with it?

I am now almost certain that the controller is not up to the task of signaling your drive at 100kHz +. You have two alternatives alter your requirements such that
a slow controller will suffice or get a decent controller.

Hi Craig

Well that is a bad news, but good to know the cause of the problem, On my alternatives that you mentioned on my first one, what do I need to do? could you explain?

also can i add a BOB to my system in order to compensate for my short coming?

Hi there

On the  issue of oscilloscope test, Could you explain briefly how can it be done? If you have clip on it would be great. my electrical ability is not my best part.

regards
