Tuning 201's

[olf20]

Hi all, hope everyone is doing well.
I'm running three G201's with 1200 ozin steppers on my X and Y axis.
This setup is on a converted Bridge Port look alike. I have read as much
information as I can find, but still don't know how to fine tune my steppers.
I'm running Mach3 and have set my accel, and rapids per Mach Manual / input from others. As the system is running ok, I continually find that as the mill is running, the X and Y motors make a vibration noise. If I increase my feed rate up to 20 to 30 IPM they seem to smooth out.
However when I want to run some engravings or some fine detail work they are quite noisey at 10 to 15 IPM as they pass thru a certain RPM.
I have read that there is a trim pot inside each drive. Are these to be adjusted to fine tune the drives to achieve optium performance???
Thanks for any help!!

easy..[I assume], just like it says in the manual for the 201....

set a slow speed, they say about 1/4 rps, and set the trimpot for least noise...

here's a link to the pdf manual

I don't have 201's, waiting for my first set of 203V's

enjoy..

Thanks vladdy! Some how I missed that in the instructions.
I will give that a try and see if it improves the motor noise.
Thanks again!

The 'ADJUST' trimpot cancels all residual motor vibration at low speeds. Adjust it per the manual instructions. All will be good with the world when you do.
