[color=#202124]Hello
I made a cnc with an arduino uno without using a cnc shield.
My problem from the beginning was that when the spindle turning on, the Arduino Stop coding and the connection with it disappear. Sometimes it happens even by turning on the power switch.
I replaced the Arduino cable and the Arduino itself many times, but the problem was not solved.
So I have to turn on the spindle manually and then connect the Arduino to the laptop to keep it connected.
I think noise is the cause of this problem.
Is there a way to solve this issue?
Thank you![/color]
Have you connected the green cable?
Hi ,
How are you starting the spindle?
Are you using relay?
If it is, try to mount a snubber on the relay contacts.

Hey
Yes i used relay and snubber .
But i think problem is noise in spindle .
Are you using shared usb hub?
if yes, connect the board directly to the pc usb port (not via usb hub)
