Re: Motor Noise?

Hi,
I found when I used a computer supply to run my controller
things got better. My homemade power supply would allow noise
from my solder station to get through. A real shocker to see
the motors jump when the station is turned on or off. The solder
station has a transformer. When the rotory switch is activated
several times in a row, my motors would jump. Using a shop vac
on the line really caused problems. With the computer supply
installed the problem has not shown up. A router really makes
line noise. Adding a speed controller has made it show up
sooner.
Been there had that
