Re: Electrical Noise


 

i did all these steps at some point and just looked at services and found that all sorts of shit was now running. i have no idea what started things that were. disabled before.?

i checked the device manager and found a bunch of stuff that did not have drivers.? iremoved them all and when starting again windows tried to install all this stuff that did not seem to be necessary and since the machine is not connected to the internet it did not find the drivers and i was back where i was with the non functional stuff int he device manager. in the process it had turned several things in services to automatic that i had disabled and turned them on.?

i am going to do some tests with a lot of repeat moves at different speeds and see how repeatable my positioning is.

i noticed that two of my stepper signal lines are not shielded. i am using Gecko servo drives. should i replace the lines with shielded wire??

any point in putting ferrites on the wires? will they work at all if i have no ground wire and just step direction and common through a ferrite? i know that ferrites work by canceling common mode noise but will this work with three wires step direction and common in the ferrite? i would like to avoid changing the wires because it will be a bitch but am willing to do it. sticking on ferrites will be a lot easier.

also, anyone have recommendations for the best pulse duration for Gecko servo drives and also debounce time?

Here is a list of things that you want to check with your OS

NOTE: Before doing ANY optimising, run MAch3 first, odds are you dont need to optimise.

?????? and before optimising, use msconfig to shut off all Startup Items, then reboot.

????????????Killing stratup Items fixed 90% of computers having any troubel with MAch3.

????????????Optimising should NEVER be done priot to knowing a problem exists.

The little balloon from Microsoft is a real indication.? Other issues might well be noise.? The DC Servo supply (105VDC) has a big honking line filter.? The 60V stepper motor supply does not and I've been thinking about adding it.? Or more ideally replace the stepper on the knee with a servo (AC or DC) since I have extra STMBL servo drive kits and the one smaller Bergerda.

?

Need to look up what the Automation Technologies stepper motor torque falls off to when I'm doing 25 IPM.? That will tell me what I need for continuous torque from a servo.

?

I wanted to keep the Stepper Power supply because I may add stepper motors to things like tool changer or perhaps the quill.?

?Don't you hate it when a problem is spurious and intermittent! Years ago I ran into a similar problem. Then I was using a C10 but changing the breakout board to another design still didn't solve the problem. What I did was to add an AC line filter and the problem went away.
