LED Lighting flicker with moving steppers



  • Hello guys,

    I do have a problem with LED lighting inside the printer flickers then steppers are working. LED lighting is connected to the 24V power supply. Any idea what it might cause or there to start an investigation? Thank you in advance.

    Is it mechanical or electrical?

    If you wiggle the LED connections can you cause it to happen?

    Are you using a PWM controlled port for the LEDs? You could try a higher frequency.

    What is the power supply? Is it underspec'ed for the load?



  • Hello @Phaedrux I did found the issue, the problem was in a touch button terminal, it wasn’t well connected and I guess then steppers motor moving it was enough vibration to cause slight wigle in the crimp...
